I just got the Lightspeed Attenuator. It came quite simply but securely packaged. The design is pleasant and solidly built. Was excited as I've read so much about it in the forums. Wanted to see if all the hype was for real.
After running in for about 4 days, I can honestly say it has lived up to the hype. Through my Esoteric transport/Bricasti DAC, which itself was already very transparent, the Lightspeed made the music flow even more freely - there was more detail, greater sense of ambience. Even at low volumes, the music just flowed. Quite remarkable. The staging is wider than my original set up. Bass was articulate, and voices were very life like. Instrument timber and inner details shone.
Overall, I'm a very satisfied customer. Amazing sound at any price. Yet the price is A$470 which makes it the best value component of my system. |
Well to answer the question, IMO a resounding YES! As a long time user of George's preamp I wanted to just express how happy I am with it. I have owned several active preamps and transformer preamps over the years and by far the Lightspeed is the most transparent I have owned. I have a collection of equipment, but no matter what I try, I go back to the LS. I am currently running a simple system consisting of an upraded MiniMax+ DAC, Lightspeed, Hypex Amps and a pair of super transparent Yamaha NS1000. No preamp conveys the music IMO as the Lightspeed does. :) |
3 x the price yes, remote yes, same build no, they use the auto-cal "forced matching" circuit to save on production/labour costs as I outlined in my last post.
Cheers George |
So Tortuga is doing the same exact build as you but with a remote and gets $1.2K for their unit? |
Yes we tried doing the same auto-calibration system in many different configurations all with the same negative results to the quality of the sound.
Documented years ago in diyforum, we tried many auto-calibration circuits for the Lightspeed Attenuator, to try to save a large percentage of production costs, of parts costs and labour cost and of the tedious task of quad matching the led/ldr's.
Active auto-calibration (or to give it a more understandable name) "forced matching" circuits have to be attached to the signal carrying output, there is no way around this.
On all the auto-calibration circuits we tried to save on these costs, we came to the final conclusion that they all interfered with the purity of sound. In that they added a highlighted sound to mid to high frequencies. And in effect seemed to reduce the bass a touch at the same time.
So to cut a long story short we stayed with the purer far more costlier system of quad matching all led/ldr's for the Lightspeed Attenuator and auto-calibration was not considered option no matter how well it was designed.
Cheers George |
LDR products from Tortuga has a remote and my wife needs one. Has anyone compared the LSA to the Tortuga? |

Hi Lacee, you could change the gold rca's that I use and replace them if you wish with the Furutech Rhodium ones. NB: If you want to do this let me know and I'll give you the dismantling procedure, it's not what you think, and can be tricky without knowing. Just make sure you don't use the plastic insulation washer/s, as the body (ground) of the Furutech rca must be in contact with the Lightspeed's chassis, to maintain it being an RF (radio frequency) sheild. http://www.furutech.com/2013/01/27/1837/Cheers George |
George, that's not going to happen.
He's perfectly content with the way his system has been voiced and the ARC pre amp is almost the least costly component in this set up.
As much as I would like to do the comparison, it's not going to happen, and I wouldn't even ask to do so.
It's always a great learning experience for me to bring over a few lps, or cd's and have a listen to them on his set up.
It is always as much a learning experience as it is a pleasurable listening experience.
Afterwards I listen to the same tunes on my system,making note of the areas that my set up falls short of his.
Then I experiment within my price range to try to improve what I have to make it sound similar to his.
Similar, yes, the same, never.
As much as the naysayers claim that only fools throw away their money chasing after the illusive absolute sound, money when spent wisely, does make for some very exciting listening sessions.
Most of the reviews people read are taken with a grain of salt,some cry foul and say they are bought and paid for.
However, until you hear some of these exotic items properly voiced, you will understand that fairy tales do come true.
You just have to pay hard coin for that experience, or find things that come close that cost much less.
The LSA is one such piece in my opinion.
I am certain Sam Tellig was never paid to say nice things about your Volume control,and it certainly isn't priced anywhere near most of the pre-amps it's been favourably compared to.
I would also like to hear what the ARC pre-amp would sound like in my system, but alas that's just a dream.My friend sets things up and that's the end of it.
I do have two friends with Acoustat speakers and the Acoustat servo amps, one a newer 3 panel (flat) and the other a 4 panel.
One uses an Atmasphere MP3, with Harmonic tech balanced cables into his amp which isn't balance, but was retrofitted with XLR jack, so it's quasi balanced and not the true measure of Ralph's genius(I used to own the same pre-amp, and it was great in a different set up with the Atmasphere S30 and stacked Quad 57's).
My other friend has the Audio Valve Eclipse, which I also owned in a different system.
So I do have personal experience with these two pre-amps when used with Acoustat amps and speakers, just not direct experience in my Acoustat set up.
Do my friends systems have anything that I think my system lacks?
Nothing, in fact, they always remark about how clear my system is.
But then I am more anal about stuff like fuses, and room treatment and the importance of clean power and using a good audio rack(Grand Prix Audio).
Because of my obsessive ways or their lack of them,I can say that the LSA is in no way shamed by either of these two very fine pre-amps, as it is set up in my system.
As I stated I've owned some pretty good pre amps(Conrad Johnson Premier two, Blue Circle fully tricked Galatea,Levinson ML2,Meitner,to name a few)but not in the system I have now.
I can only state that I have no desire to revisit them or seek out any others to replace the LSA.
It makes me happy,whether I paid $500.00 or $50,000.00,I would still find it hits all the marks that matter to me.
If I had one thing that I would change with the LSA, it would be to replace the RCA with the top of the line Rhodium RCA's from Furutech. These made a nice change on my Servo amps, and then my cables that use the 102 R Rca's would see a perfect match.I like consistency in connections,but I did admit to being anal. |
It is the most revealing, easiest to listen thru,least expensive(I 've owned some pretty expensive esoteric preamps over the past 40 years,tube and solid state)and quietest "pre amp"I've ever owned, and will be my last.
Are there better ones out there?
My friend has the ARC Ref 10, before that the Anniversary 40.
I think they are pretty special in a system that is completely different than mine.
But I don't think I'm missing too much.
At least I don't feel short changed and I have no desire to chase after either of those preamps. Wow, I feel humbled, and I thank you very much for your fine review above of the Lightspeed Attenuator Lacee. This maybe asking a bit much, not of you so much, but of your friend, as it would be very interesting to know how the Lightspeed stacks up against his ARC Reference 10 in his system. Cheers George. |
What I have learned is that volume controls even run wide open into a passive pre still have colourations.
The manley Steelhead is still a good phono/preamp in a vinyl ,cd set up.
You really don't need another preamp to be satisfied.
That was the way I enjoyed my system, until I got the LSA.
That was a game changer.
I took the Esoteric out of the Steelhead and ran it into the LSA.Yes a bit of wire changing, but I am a fan of the purist school of audio,so one set of inputs and a bit of wire fiddling doesn't bother me if it's for the betterment of the sound.
The sound of the cd player thru the LSA directly into the amps(bypassing the Manley)was much more powerful sounding.More dynamic, a fuller ,rounder sound, and more inner details.
All the kinds of improvements you tire reading about, but nevertheless,were there.
We really do need to invent some new vocabulary to describe these kinds of improvements,because I and no doubt countless others, tend to take such praises with just a hint of scepticism.
And that's a shame.
Improvements are improvements, no matter how hard it is to describe them, it's easy to hear them when they are there.And you can prove it to yourself that your ears are not fooling you, nor is it self delusion simply by going back to listening to things the way they were before.Then listening to the new way.
I much preferred my cd/sacd replay thru the LSA.
In fact so much, that I was in a dilemma.
Why wasn't I enjoying my vinyl system as much?
I addressed all manner of set up with my SME arm and table and Clearaudio cartridge.
I use the same interconnect from the phono stage(Variable out)as I do from the cd player into the LSA.
What I eventually did was run the Manley as just a phono stage.Which most reviews of the steelhead have stated, and I ignored.
Running it from the fixed outputs bypasses the volume control altogether,but cancels the use of the Sum or mono function.I do play mono recordings from time to time.So I was reluctant to run the pre in fixed mode.
Doing so, however, proved to be the answer to my problem.
Vinyl is now on par with the punch and clarity of the digital set up.
So as good as the Manley is as a phono stage with the added option as a volume line stage,I believe the volume control is it's weak spot.
This is not to discourage anyone from running it this way.
It sounds good.
But if sounds good isn't good enough for you, and vinyl is important, then run it in fixed mode into your preamp of choice.
In my case, it's the LSA.
If vinyl doesn't matter,then try the LSA direct into your amp from your digital source.
I think you will be more than pleased that this level of sound quality is available for so few dollars.
Just make sure you try a decent linear power supply.
I use the TeraDak.
Without a linear power supply(I have not tried battery),you'll never know how great the lSA is.
It is the most revealing, easiest to listen thru,least expensive(I 've owned some pretty expensive esoteric preamps over the past 40 years,tube and solid state)and quietest "pre amp"I've ever owned, and will be my last.

Very good Lacee, you couldn't ask for any better, enjoy.
The Lightspeed's volume action/structure is logarithmic, and after 1 o'clock it rises exponentially in level till full.
So as you can see at 1 o'clock you are at around only 30% to 40% of full volume you still have 60% to 70% of gain and head room level to go. There is no need for the extra amplification gain of active preamps.
Theses days there's enough gain in cartridges/phono stages, so owners can take the active preamp out of the system, and reap even more transparency/dynamics from their systems with a passive preamps.
And because they are dc coupled (no coupling capacitors in the signal path) the frequency response is greatly improved, passives are 0hz to well over 100's of mhz (megahertz) in frequency response, interconnects become the limiting factor for the high frequency limit.
Lacee once you've listened for a while can you give us a review of replacing the active preamp with the Lightspeed Attenuator.
Cheers George
|
About 1 O'clock,and that's with the gain of the Manley set at 50db, the lowest setting. |
That's great to hear Lacee, echoing many of my customers are reporting back to me and say that with the Lightspeed Attenuator as the preamp it's the best they have ever heard their vinyl/phono sound.
I did a bit of searching and found your Steelhead, has a great low 150ohms output impedance. With the Clearaudio Talisman Gold V2 you are using, where is the Lightspeed's volume control when listening to medium loud volume.
Cheers George |
I now use the fixed output on my Steelhead,bypassing the volume control of the manley.
This has further improved my enjoyment of the LSA.
Using the LSA with the Esoteric cd player into my amps was very revealing, and my old way of running the Manley with variable output(vol at full on the Manley)to retain the mono function,left me preferring the cd sound.
Not so anymore.
The manley is now just a phono stage, and a better one than I thought it was.
The LSA's transparency is quite apparent on vinyl as well as CD/sacd. |
Graham Slee's 2006 interview with TNT (http://www.tnt-audio.com/edcorner/july06.html) offers an eye-opening overview of the stark implications of RoHS for small to medium businesses, best summed up by his assessment that "all this legislation has a soul destroying effect on the designer who tries so incredibly hard to share his/her talents with the music lover, only to be shunned by what would seem to be ruthless dictators." Amen!!! |
This is vintage EU mind control: identify genuine existential problems, say the girth of bananas, to justify a metastatic bureaucracy, whose days, judging by the latest EU Parliament elections, are numbered. |
So is the Beryllium(Be) used in Focals/JM Labs and other speaker manufacturers that use Focals top tweeters. So is Yamaha NS1000, NS1000X and NS2000, tweeters and midrange units. So is NOS and OS tubes that have Nickle(Ni) inside them. And so is the lead(Pb) based solder hiend manufactures still perfer to use. I can go on and on, at least the Silonex LED/LDR package that the Lightspeed Attenuator uses, are hermetically sealed within a tough hard acid resistant plastic case, I don't think anyone is about to open up a Lightspeed Attenuator put one in their mouth and crunch down on it like a boiled lolly. It's not "Cadmium Gas" it's Cadmium Suplhide (CDs) solid. http://en.wikipedia.org/wiki/Photoresistor http://en.wikipedia.org/wiki/Cadmium_sulfideCheers George |
This only applies to UK and European Union members.
There seems to be complete ignorance about these Light Dependent Resistor products. A word of warning really needs to be published about LDR based pre-amps. LDRs contain Cadmium gas which is lethal (kidney or liver failure) if eaten or breathed and is a long term serious health (Cancer) risk if just touched on a regular basis. Because of this it is illegal to import or sell these items within the EU as they are not RoHS or WEEE approved, so cannot be given a CE mark. This is true for both kits and built products. |

Hi George,
I don't use the Isolator cartridge/headshell de-coupler pictured at
http://www.blackpearls-shop.de/DECCA-AEC-LONDON-REFERENCE-TONABNEHMER
Instead, I couple the Decca to the arm and the arm to the 'table with Mapleshade's Nanomount System,
(http://shop.mapleshadestore.com/prodinfo.asp?number=NANOMOUNT).
Mapleshade's no-nonsense vibration control products shame anything else for a fraction of the price, which is exactly what you've managed to do. Its founder, Pierre Sprey, fathered the legendary A-10 Warthog, recently rescued from extinction by Congress. It's the only USAF aircraft designed solely for close air support capable of extended loitering over the battlefield, to devastating effect, again for a fraction of the price of an F-35. Have a look at this: http://www.motherjones.com/mojo/2012/01/a-10-f-35-air-force-budget.
Your LightSpeed is the stealth version A-10 of the audio battlefield. Simply devastating! |
|
My analog front end is a vintage Verdier driving a London Decca Reference cartridge on a Cartridge Man Air Bearing tonearm. With its 5 mv output the Decca is not exactly shy, so signal strength is not a concern with the LightSpeed .
I use the phono stage of a modded EL34 type Scott amp, which in terms of what I would consider absolute musical value, is without peer. The ability to further tap that value upstream via the REC OUT into the LightSpeed Attenuator is the equivalent of adding Bybee Golden Goddess 'Super Effect' Speaker Bullets, which to me, was a revelation, and is of the same order of magnitude as being able to bypass that dismal digital attenuator on my Oppo, whose potential has finally materialized.
For me, pace and tone are paramount, and trump imaging any time. Music is not about hollow graphic photography, but about living the performance. The Lightspeed clarifies intention and complex interdependence between notes the way a juggler keeps his balls, up in the air where they belong (sorry about that).
Insofar as the only weakness of the Lightspeed is the additional interconnects required, time permitting I hope to experiment with the diy version of the Tempo Electric Aurum Ag Hybrid interconnects, which should do justice to this exceptional little gem. |

Hi George,
I just had a quick glance at the Audiogon thread to figure out whether I can find a better power supply than my decommissioned Prius auxiliary battery, and I fail to understand how a Teradak, with or without a fancy cord, could offer an improvement other than convenience. I guess the answer is that you haven't felt an overwhelming urge to try it yourself. Not being an exhibitionist, I personally think that my best audio component is my brain with ear input, which in addition to being portable and self-powered, doubles as the biggest sex organ, but I'm still burning it in at sixty-six, and it keeps improving. I strongly believe that battery is the "technically" the best form of dc supply for the Lightspeed Attenuator. But sometimes I forget which is on mine, the battery or the linear wall wart, they're that close to each other. Sam Tellig of Stereophile uses both battery or wall wart on his Lightspeed, and so does his guitar teaching son on his Lightspeed. And both can hear a slight difference but can't say what that difference is. As for the Teradac power supply, if you technically want a very good mains powered supply for the Lightspeed that to me is total overkill, this is the one to get. And it's only $44. Some here that have used it, swear it's the ultimate mains powered supply. I have never used one so I cannot comment on it, but on paper it's miles ahead of a linear wall wart, but to me technically battery is even better again. Cheers George |

I compared the LSA with a switch-mode ps and the linear TeraDak 9v supply discussed earlier in this thread. I am going to report a null result: I could not reliably differentiate between the sound of the two. The TeraDak carried no benefits in my system. Hi Julian, I noticed on another forum you did a comparison with the Lightspeed up against another clone, and mentioned the Lightspeed Attenuator had the better bass performance. I believe there could one of 3 factors for this difference. 1: The main one I'm leaning towards may be that the Lightspeed has no contacts in the signal path, where I believe the clone has, as it has input switching. And the whole point of the Lightspeed when I first built the original in the 70's was to eliminate any switches or volume pot wiper contacts from the signal path. 2: I also use quad matched LED/LDR's in the Lightspeed, this keeps the i/o impedances more stable, and also gives a better logarithmic feel to the volume control, I believe the clone only uses 2 x matched pairs. 3: I use the more expensive NSL32SR2S, where the clone from what my spies told me does not. Cheers George |
Please do try the LSA with your phono stage.
I run my Steelhead volume full out and the LSA under 12 with very good results.
In my system, the Terra dak with upgraded power cords in conjunction with dedicated lines is an improvement over the stock LSA and walwart.
No doubt your power supply is also much better than the stock walwart.
I use the Annaconda power cord only because it was a spare,but I would assume any upgraded power cord would work quite well with the LSA/TeraDAk combo.
However if you haven't been able to hear the differences power cords can make with other components, then by all means use whatever you have at hand.
It's not about one-upmanship,just being practical without selling it at a loss.
Besides what would I spend the extra dough on? |

The only limitations I can think of, have nothing to do with the sound: leaving the volume control half-way to extend the life of the optoisolators took some getting used to, and indeed the lowest setting lets will let some minimal signal through, which compared to my previous setup, however, is well within my tolerance, and greatly superior to my earlier direct CD to amp connection. The overall experience is far beyond my expectation. This is a product that I will not be parting with, period.
Erwann (Answers | This Thread) Glad you like it so much Erwann, as for leaving it at 12o'clock when not listening, this is not set in stone, as the leds should last 10-20 years at full power, which I never run them at, and by leaving it at half volume should double or tripple this life. PS don't forget to let us know how your $15K!!!! analogue source sounds through it when you get the chance, as analogue lovers have told me it's the best they have ever had their records sound. Cheers George |
Hi George,
I've been enjoying your Lightspeed Attenuator for three days now, and it prompts the following remarks.
As a lifetime analog fan, I only lately invested in a truly great CD player, an oppo 95 with Ric Schultz's all-out mods, only to discover that the digital volume control noticeably degrades information at lower -and what I would consider reasonable- levels. Additionally, the increments are less than subtle, and the lowest audible setting is still too loud for my taste. A friend told me that digital volume controls deserve to be banned. I concur.
In my experience a system's ability to resolve lower levels is essential. Not being the diy type, I started looking at stepped attenuators that plug directly into the amp output, and therefore would require one less interconnect. The only two I found, Ric Schultz and Scott Endler's, were unfortunately no longer made, and TVC's have their own issues. After discovering your LightsSpeed Attenuator on diyaudio.com, I ordered one a couple of weeks ago, which arrived safely ten days later.
I think the best way for me to describe the LightSpeed is that with the CD volume control set to maximum, I can now listen to my interconnects, not to the unit itself, because in every respect -style, size, sound, and setup- , it simply stands out of the way. I power it with an older car battery. It's always difficult to describe a product which has no characteristics of its own, whose presence is in its seeming absence, which adds or subtracts nothing, but the end result is that I now listen far more often to far more music which is far more enjoyable. For $450 I'm finally experiencing the full potential of what I consider to be an exceptional CD player, which now comes very, very close to my $15,000 analog source. I have yet to try the LightSpeed on the REC OUT of my phono preamp, probably because I am enjoying it so much on digital.
The only limitations I can think of, have nothing to do with the sound: leaving the volume control half-way to extend the life of the optoisolators took some getting used to, and indeed the lowest setting lets will let some minimal signal through, which compared to my previous setup, however, is well within my tolerance, and greatly superior to my earlier direct CD to amp connection. The overall experience is far beyond my expectation. This is a product that I will not be parting with, period.
You asked about the volume setting for normal loud listening with the Oppo at full. It's at ten of twelve maximum. If I want to increase that setting, I can then use the remote on the oppo while retaining excellent definition. |
I compared the LSA with a switch-mode ps and the linear TeraDak 9v supply discussed earlier in this thread. I am going to report a null result: I could not reliably differentiate between the sound of the two. The TeraDak carried no benefits in my system. |
|
That's cool, Detredwings. Can you provide a link to your battery pack.
I bought a battery for my LSA years ago and the differences were subtle at best. But the battery was suspect and died within a month. I'd like to try batteries again even though I'm very happy with the Teradak. |
I have been using my dual mono version for a few months now. It has always been dead quiet and did great things right out of the box. I have recently added the rechargeable battery and it has pushed things to an even higher level.
I know that some people said that it wouldn't make a difference using a battery supply but for me it did. It sounds even more natural and more information comes through. |
No problems with my Acoustats,the ones with the servo charge tube amps. |

Has any one used his LSA with active monitors?
mine do have an input impedance of 10KOhms, which is not the recommended 47Kohms.
Output impedance of the source is extremly low though.
any thoughts? It all comes down to what the source can drive, because it will need to drive the combined load of the Lightspeed and the active speakers If it (the source) has a very low output impedance say below 50ohms there should be no problems. But say it (the source) has a tube output stage then some of these can be very high in output impedance ( some up to 5Kohms), they could have trouble in this particular case. Cheers George |

George will these cables fit the 2.1mm dc connector on the lsa. Yes, the Lightspeed Attenuator has a dc socket that has a 2.1mm centre pin, 5.5mm external, plug. The centre has to be positive which I believe the TeraDac is. Cheers George |

~Tom in Sacramento |
I pushed the TeraDak ac input plug into the LSA and, though it isn't the right size, it powers the unit. Problem solved. Thanks for the advice, Banquo & Lacee.
I'll try and do some careful listening and come back with a report on how the TeraDak compares with a SMPS wallwart. |
Never had any problems attaching the two with what came from TeraDak.
Perhaps you should contact them for the answer,and enlighten others who may want to purchase the "newer"units if in fact they have made a switch.
Perhaps they are offering an alternative to the previous cord. |
Jult52: I just use whatever came stock with the unit; no adapters needed. I do note that the cord juts out a bit when plugged into the LSA, but it is powering the unit as it should.
Perhaps the Teradak people changed their stock cord? |
Hi everyone, I have a question about the TeraDaK U9VA power supply, which I recently bought. The ac input is too large for the 2.1mm connector used by the Lightspeed. I asked the TeraDak manufacturers how to convert the plugs but the language barrier is preventing me from getting an answer.
What adapter have the folks using the TeraDak with the Lightspeed been using? If you have an online link, that would be very helpful. Thanks. |
Great Passive Preamp. Received light speed from George two weeks ago. In my system the light speed has great dynamics and clarity. System is primaluna prologue five tube amp and Tyler acoustics PD 15 speakers. Thanks George for a wonderful product. |
Just wanted to thank George for a great job well done with the lightspeed attenuator.. The music in my system has really opened up and I'm hearing instruments more clearly in background with better detail then I ever had before.. The instruments sound so realistic as if I was right there and the voice's are so clean and airy..
I'm running the lightspeed with pass labs x250.5, Oppo bpd-105 and Eggleston fountain 2 speakers and am very happy with the results after over 20 years of listening my search is at last over..
Thanks George for a great product with good customer service.

Dhcod hi, I had a bit of a search and yes your Purest Audio cables are very good low capacitance ones. They are fine to use with many tube and most passive preamps, and will not cause early (into the audio band) high frequency roll off. I would keep these to a max length of 1.5mts from pre to poweramp. I looked at most of the ones they give specs on, and they give the 1mt length pF (pico-farad) capacitance and all that I saw are under the 100pf per ft measurement I gave earlier. This is good to know that some cable manufacturers are responsible and doing this specification for their customers, who know how to use it, for their systems compatibility with them. http://www.puristaudiodesign.com/products/interconnects.phpCheers George |
I didn't measure capacitance or anything but after trying quite a few interconnects, I found the Purist Audio Museaus to work fantastically with my Lightspeed. Cleaner, clearer, more true..... |
Yes this what good interconnects should be, as little as possible capacitance.
Otherwise if over 300pf total for a 1mt length, they will start to create 1st order (gradual) HF (high frequency) roll-off's into the audio band when combined with nearly all passive preamps and many of the tube preamps as well.
Giving the impression of sometimes sweeter highs less sibilance (if the system has some).
And because the top end has been curtailed a little less detail, it can also give the impression of more bottom end or richer lower midrange.
Cheers George |
