Stltrains,
I am glad to have played a role into helping you choose the AH preamp. I am happy now with the sound of my system. I am glad that you have a very nice system which you are enjoying as well. Let us know how those Lessloss cords work out for you. Enjoy the music, my friend.


Just wanted to ad that Josephs' Power cord is a joy. If you are at all interested try upgrading the termination to Oyaida connectors. It makes the cord SING!

Harmonix Studio Master and Black Sand Violet before the awakening.
It is interesting how different connectors sound with different conductors. I am currently experimenting with an OCC copper conductor power cord using the new Oyaide P-004 and C-004 connectors. I also have one of Joseph's Premium power cords and am using the a FIM 303 male connector with it. Joseph uses the basic Wattgates on his cords.
Can any of you guys enlighten me on the basic sonic signature of the four levels of AH cables available (Concept, Harmony, Transparency and Dimension), and whether the conductors in these cables copper or silver? At the AH prices, I would be most interested in the best performance regardless of price (probably Dimension or Transparency?), and I would be comparing them to other very good cables, but I cannot find that information on the website. Also, what are the X-series speaker cables shown on the website? is that a former name of one of the four levels listed above? I am going to audition the Dimension interconnects and was just curious for a little more information and some user feedback.
Mitch...All I can say is that I just received Joseph's Dimension speaker cable. Absolutely wonderful tonality, clarity, detail and presence. In my system, it relegated to obscurity some very fine Siltech cable. I agree with you---at AH's prices, just go for the top of the line Discovery.
Pardon my mistake ! Of course, I meant the top of the line Dimension, not Discovery.


Just one more observation. Joseph's IC(dimension)seems to reflect his passion for noise as a curse on the signal. Terrific balance and very low noise signature.

Gabriel Gold Revelation, KCI silkworm are two well known and very good cables. Its a matter of taste.
Mitch i understand your frustration with Audio Horizons Web site concerning Dimension ICs and Speaker wiring. The only mention is the price list. Let me say though that after getting and using Dimension ICs and speaker wire i am totally floored at its quality build and of course its musical presentation. In my case i retired my JPS Superconductor 2 ICs and speaker wire. I would not have believed it. Now my whole system is Dimension wire. I went the same route as you the 30 day trial. I believe that before you buy if possible you should try. Hope this helped and good luck.
La45: You are right on the mark. I too sense an extremely low noise floor. One can pick up on recorded sounds that resemble the barest whisper. I'm now extremely interested to hear that Dimension interconnect though I currently own two other highly regarded and very fine sounding brands.
Thanks Stltrains and others for the comments. I believe Victor is going to send a pair of the Dimension IC cables for me to try when I audition the TP2.1 preamp. I will be comparing them against my Purist Aqueous Anniversary cables in the position from source to preamp. I appreciate the shielding and vibration efforts reported to have gone into the consruction of the AH cables, but I was curious that I could find no reference to the type of wire used (silver, copper or an alloy).
Mitch here is a email i received from Joseph regarding the differences in Transparency and Dimension, this was last month. Maybe he doesnt want the conductor material known, not sure though. Maybe he will chime into this discussion.

The geometry is total different in between them, Dimension takes double time to build and the material.

Best,
Joseph
I would like to comment on some of the remarks made about the Audio Horizons website's inadequacy. Joseph and I couldn't agree more and we are working to correct it. Our problem is both time--Joseph has little to spare--and money. Again Joseph has little to spare. Still we are in the process of redesigning the website from scratch, includng the retaking of our photos, whose quality is modest at best. It is a big project for us to understake, but hopefully in the next thirty to sixty days you will begin to see the consequences of the changes.

Meanwhile, I encourage those of you who have questions which are not answered either in our ads or on the website, to please contact me. I'll do my best to answer. And if I can't, I will put the question to Joseph.

Meanwhile, I want to thank all of you for your continuing enthusiasm and support. Joseph and I both appreciate it.

Victor
Hi Victor, thank you for your concern with providing us the most complete information you can. I know your posts here are much appreciated, but please don't sweat the website. Building a website is like painting the Golden Gate Bridge...once you finish it's time to start over again. Besides, if the website answered all our questions, we wouldn't have as much to talk about on Audiogon. I was simply curious regarding some of the technical aspects of the cables, and specifically the wire material - copper, silver or alloy. I realize some of that information may be propriatory, and that's ok too. The other reason for my post was to get some user feedback, specifically on the Dimension IC's, and the difference between the Dimension and the other AH lines, prior to my audition. Those are questions I wouldn't normally bother you guys with, since your time is better spent building equipment and cables.
Mitch, I am trying the Dimension IC cable in my system again. I currently own his Transparency cable and use it throughout my system - power, IC's and speaker cable. I tried the Dimension before and prefered the Transparancy in my system at that time. I have a new room and amps so I want to compare them again.

I found the Dimension a little darker sounding in my old system. The Transparency cable sounded more like it's name.
It could be the Dimension cable was not fully broken it. We will see.

Still looking forward to the coming AH tube amp!!!!

I would imagine that Uncle Pat is too busy enjoying his new monobloc amps. (o:
Some of you who have indicated an interest in the TP 8.0 might be interested in a 6Mooons review of the TP 8.0sMCpn which will appear in the next couple of days. the review includes some photos of Joseph's listening room and sound system and mine.

We've also been told that a review of the TP 2.1nB/8.0iMCpn
wil be appearing in Stereomojo soon.

Victor
Some of you may be interested, also, in other sound system development work that Joseph is doing.
In a thread named "Sonos Questions" I reported on some improvements that Joseph has made to my Sonos digital source. The external power supplies that I am testing have greatly improved my pleasure in the Sonos system. Sonos provides an excellent user interface but the sound quality needed some help. Joseph's power supply improvements have delivered that help.
Hi guys,
If you know of anyone who is in the market for a TP 2.0 that has been upgraded to a 2.1 there is one available one the following site canuckaudiomart.com,under the pre amp category.
The seller informs me that the AH doesn't have the synergy he's looking for.It's been very quiet on this thread,trust everyone is well.
Markwatkiss: "... trust everyone is well."

My TP2.0 is still doing great and I enjoy it immensely. My amp, on the other hand, rolled over on me (don't ask - it involved sparks...) and I'll be down and out for about a month.

The good news is that I'm getting an "upgrade", so it should be even better when it returns.

No music... stinks.

Question for AH 2.0 and 2.1 owners?

I am in the market for a new preamp and looking for the following physical/mechanical requirements:

balanced in/outs
remote control
HT pass through or unit gain

I have certainly read quite a bit of interesting comments on the AH preamp and also some accusations in other posts, but a trial period will ultimately tell the value for me.

My questions are:

Does the 2.1 have an HT pass through or unity gain, I didn't see a reference to this on the AH site.

Can anybody comment on the suspected symetry with Watt/Puppys (5.1) and Krell FBP amps? Soundstaging depth, width and focusing abilities of the 2.0/2.1? Smoothness in the treble region? Balance along the entire frequency range?

Thanks, ckoffend
Hi Ckoffend

Yes, I think Joseph can build your pre with an HT pass through. I would email him to confirm. The 2.1 is very smooth in the treble and would be a great match with a nice SS amp like your Krell. Stage is wide and deep. One of the preamps strenghts is its balanced from top to bottom.

I think this pre would add a nice element of body and texture to your amp and speakers. It has done so with my systems. I did use the 2.1 with a Belles SS amp and found the combo very nice indeed.

Just try one! Nothing to lose as you can return it if you choose.

Based on what you need and the rest of your system I would go for the top of the line in terms of add-ons. Get the best with the Siemens tubes if you can afford it. I have this unit with remote.

Good luck.

Bill
Some of you might like to read the latest review of the Audio Horizons TP 2.1 in Stereomojo: www.stereomojo.com

Victor
Yes, great review. It's nice to see Audio Horizons getting the positive press it deserves!

Congrats!

Rob
FWIW, I did communicate with Victor at AH regarding the HT passthrough and it was reported to me that it is an option or feature than can be integrated into the preamps, and at a very, very reasonable price. IMHO, this is a real plus with this preamp and AH should consider promoting this as a viable option as in my opinion, it opens up the market for this preamp. We have all seen the numbers of Threads of people looking for preamps (tubed or SS) with HT passthrough and/or unity gain. While these preamps/features are becoming much more common there are some shoppers who will not consider preamps that do not have this feature.
Hello fellow AH TP 2.0/1 owners. This thread has been awfully quiet lately. I have been enjoying my original TP 2.0n preamp very much lately. I hope everyone has been well and enjoying their systems. Any new users care to share your experiences? How about current users with any new updates and experiences. I'm going to experiment with a few different power cords next week. I also had my vintage H/K tuner tweaked and aligned again and the NPR station here is sounding wonderful tonight.
I've been talking with a fellow that bought a premium version TP 2.1.He had reviewed this thread and decided to make a move.He's also using a REF 2,which peaked my interest.He becomes more impressed with the performance of the AH with each progressive e-mail and has detailed the superiority of the AH in several areas over the REF 2.
Sherod,I'm always interested in power cord comparisons.
Forgot about active pre amplifiers, they all degrade sound. I would recommend you to check transformer pre amplfiers such as
Audio Consulting Silver Rock
Van Den Hul Passive Pre
Antique Sound Lab Passive TD
I spent a lot of time with active pre amps and decided for passive. If you want to see my jorney, pls check the link below;

One thing for the AH family I would like to query is if anyone is using the TP 2.0 or 2.1 as a full function preamp, that is with the phono stage integrated. I am considering this option, but one thing I have to say that nags me a bit about AH is that as I look through the upgrades I feel like I'm getting nickel and dimed.

Oatalay - I enjoy the passive TVCs as well (having owned and possibly reacquiring a K&K TVC) and may look into the Antique Sound Lab model. I also like the concept behind the ASL Flora with AVC attenuators and an active tube gain stage as well. The new Bent TAPs will use autoformers and those are of interest as well.
Clio09 this is what i think Joseph is doing with his options in a line stage preamp. 2.1 is available in what needs the buyer wants for his system or what he can afford. And a good thing i think.
I would be interested in what your thoughts are if you get a phono equipped 2.1.
Stltrains,

Yes that did occur to me. I do think it is good that some designers make their gear both affordable and upgradable for those who cannot afford a high cost of entry. Kevin Carter at K&K takes a similar approach on his kits. Of course, in order to match my current system I would have to get most of the upgrades, taking the cost well above what I would consider to be a bib bang for the buck. For the $4k plus I would spend on the AH 2.1 with phono there are a lot of other options.

I am very tempted by the trial offer. Perhaps that is the only way can truly tell what I am getting for the price.

BTW - I follow this thread quite a bit and enjoy the enthusiasm and comaraderie of the AH family and your support of AH products. I mean no disrespect by my comments. I'm in a very precarious predicament right now and this is a crucial time in my system evolution. I have learned a lot from this thread and hope to see it continue grow in opinions and insights.
We may all be in a "precarious predicament" when the bell sounds at the end of this trading day.
Actually, the stock market made a last minute recovery after being in the red all day and ended up for the day. Amazing with these rumors of already being in a recession, the stock market still goes through its daily roller coaster ride.
Clio09, have you considered also Promitheusaudio new mono double C-core as well. That might be an interesting option because big c-core transformers suppose to be superior to other transformers available.
Has anybody compared these to AH preamp or some TVC?
Has any one compared the Audio Horizons newest preamp to one of the Modwright preamps?
Member Markwatkiss had one. Maybe he can explain the differences in more deatil:

Hi Guys,

Well, I see one area which hasn't really been addressed properly. I have read this whole thread now. What I am wondering is, if someone has replaced the standard pot with a stepped atenuator, like a GoldPoint? It would definitely help in sonics. Plus, the tracking would be pretty much spot on, and would help imaging too.
Blindman, interesting suggestion. I also have wondered the same thing. Maybe Victor and Joseph can jump into this thread and give their opinion.


Blindamn,

Joseph might say its too expensive. But if anyone is willing to serve up their Gold point for testing, it might be interesting.


Anyone out there commissioned Joseph to mod their Blu Ray player or Cd? Was it a worthwhile choice?
Most everyone has the AH with the nB upgrades. How does the AH 2.1 sound with only the n upgrade and the stock transformers? I'm getting one in for audition in a couple of weeks and I'd like to feedback on the sound without the B option.

I've owned the DAC 2A since Jan 2006 and my system is all Transparency. Joseph also upgraded my CAL Delta transport which included replacing the transport mechanism at parts cost when it decided to give out while he had it(after 10 years of spinning CDs). Joseph invited me to his home to audition the DAC 2A where I also met Victor. Needless to say, I'm a big AH fan...

Thanks for all the great feedback I received concerning my query. The silence is deafening...
I still have the original 2.0n version and I'm very happy with it. I don't know how the added "B" version would sound. I'm sure someone will respond soon. It is interesting how this once active thread has suddenly died out. Maybe everyone is just too busy enjoying the music. Personally, I think you should get the new "n" version and let it break in for a couple of weeks and get a feel for its sound in your system. I would like to hear your impressions.
What tube.....????
link to ad
Explanation please.

I thought it was a tube section.
I was interested for a split second, until......
where are the freakin tubes????
They're in there, Mrjstark. The board on the lower right has 4 6922s.

Oddidoo: I have the 2.0n version. While stock, I added in some Amperex PQ White Label tubes and haven't seen any reason to move beyond that point.
Oddidoo,
I also have the 2.0n version and am quite happy with the fidelity.I've always contemplated upgrading to the 2.1 version but I'm somewhat hesitant.One of the members of this group moved forward and was not convinced the upgrade was sonically better,at least in his system.Others have said it's an improvement.Wherever you go there you are.
