Is my preamp useless?


I enjoy my current system, which is built around a BAT VK-52SE preamp. I listen mostly to digital, via a Bryston BDP-2 player into a PS Audio DSD. I also enjoy vinyl on my VPI Classic/Dynavector/Sutherland 20-20 combo. Like most of us, I’m usually on the upgrade path. For me, the next component to upgrade would be the BAT preamp from a 52SE to a 53SE. But something occurred to me. I don’t listen loud. The gain on my PSA DSD is set to less than 100 and the BAT preamp is usually set between -20 and -10. So if my volume control is never set in the + range, is my preamp doing ANYTHING other than attenuating the volume and serving as a multi-input switch? Is all that Super Tube, single gain stage, zero feedback, high energy storage circuitry a waste of money?

Don’t get me wrong. I am very pleased with the sounds I hear. But if my pre isn’t doing anything, then I’d be better off to sell it and get a very simple passive attenuator, wouldn’t I? If that’s the case, what brands and models should I listen to?
Thanks for any advice.

Atmasphere,
I did look up that your firm manufacture tube preamps that do not require expensive cables or do not react to cable changes. Unfortunately I am not a tube guy. But lets not go there.
So let us assume that I purchase this preamplifier. What happens to the power amplifier, sources and speaker cables? What about power cords? They also seem to have some degree of effect due to cable changes. At least in my system, the speaker cables made a huge positive difference. Or is my system completely wrong in revealing changes because of cable switching?
Thanks Grannyring for the comments. I am looking forward to hear how the LSA works for you this time.

Doubt it will be a favourable outcome, "once again". this will be the 4th time, why keep trying???

Knowing Grannyring's obsession with the TRL Dude.

Just as I doubt you would ever have a favorable outcome when comparing a active to a passive George.

Many times folks hear what they want to hear, on both sides of the fence.

Your system is fine- being able to hear the effects of cables is what comes with resolution. The only thing is, interconnects are the one type of cable that should never be able to impose an artifact- because we figured out how to stop that a good 60 years ago!

However, speaker cables and power cords are a different matter entirely. They impose (measurable) artifacts too and the physics about why are pretty straightforward although I am not sure if they are germane to this thread.
I will report back on what is. I am an open minded Aphile who is NOT tied to any one piece of gear. Goodness, Agon folks should know this by now.

The LSA is playing now and works well in my current set up.
George, I want your device to do well and that is why I try it yet one more time on a different assortment of gear. My open minded ways is always curious and willing to experiment. I love great values in audio and have learned a great deal over the past few years on building and modifying gear

I just can't fathom why some one would buy at different time 4 x Lightspeed Attenuators.
A second one I can understand, thinking, "maybe I made a mistake by selling the first one", but now a 4th one??

It's beyond me, but hey keep buying them as it keeps me in beer money.

Cheers George
I've bought the same speaker cables and integrated amp 3 times now. I haven't reached 4 yet, but maybe one day. ;^)
Of course I bought them all used.
Yeah, I did not buy the unit three of the times. This one is a friends that wants me to sell it for him. I sell gear for friends often as witnessed by my prolific feedback:) Anytime I read about dozens of folks saying a $500 passive toasted their $5,000-$20,000 active it gets my attention. Again, I have different gear that seems best matched to achieve the magic so many write about.

I may build a battery supply for it, upgrade the RCA's, dampen the chassis and use better hook up wire. Again, it is behaving nicely thus far and may indeed be worthy of a few simple upgrades.
George,
Grannyring has given logical explanations for the 4th attempt using your Lightspeed. He feels it's a very good product(and has say so numerous times0.

He feels it's a very good value.

He likes the simpler is better concept in theory.

His system make up and current components are different and perhaps more favorable this time.

He's opened minded.

I wouldn't say this sounds like someone "obsessed" with the TRL Dude. Rather with direct comparison in his system the Dude provided superior sound quality. Seems like he's been quite fair with your Lightspeed. He has more patience than me.
Charles,
John, I owned Merlin VSM speakers three times! All used. They had a certain sound that was appealing and so darn close to my dream speaker. In the end they just lacked the weight/body of music I hear live and on other great systems. The LSA has left me with the exact same past experience, so close to audio bliss but........the weight.......the body.....? Will this time be different with higher efficiency speakers, DHT amp and the Yamamoto Dac? We will see. I have it in my home to sell so why not try!


I'll just show this from another thread.

Quote Grannyring:
"I am usually 100% against passives "

Cheers George
Yes indeed, that comment was based on experience to that date. That is reasonable? Right? Experience changes opinions. We are all in a state of change if we are open to new experiences. Going back in time for a quote is a waste of time George. I really do not understand your negative ways.

Anyway, thus far your design is making me rethink what is possible with a passive. I will post my honest opinion regardless of how petty you are behaving.
Here is that comment from five years ago in the full context.
George, you totally tried to mislead others and seem to want to smear me in some way. The total context is both reasoned an open minded to your design. Quite the opposite of what you are trying to portray. Someday you will hopefully see I am an honest and curious Aphile with no conspiracy plan against your or any passive.

Like your input George. I would love to try your preamp in my system and compare to my tube preamp. I can't believe I even said this as I am usually 100% against passives based on my experience with these in the past. It's just that several highly respected Agoners seem to think your $450 unit is the real deal giant killer. I have a giant in my opinion :


No negativity or accusations of conspiracy.

Just presenting a portion of written facts/quotes.

Cheers George
I really appreciate your input on this Grannyring because you give it a better chance than most reviewers would and are sincere about your findings. We all benefit from it no matter how it has come about. It will be interesting to see if it kicks it up a notch or two by some mods. I would definitlky do that. Enjoy the journey. Thanks for sharing Grannyring.

It certainly doesn't appear that way George. It seems as if there is a LOT of negativity and accusations. That is your second post trying to proactively smear Bill's (Grannyring) testimony.
What's the matter George, not much confidence in your product? Maybe you are not totally sold on passives yourself??? LOL!!

Maybe folks should dig through your post history, and see how much love you give to active preamps, just to see if your opinion is fair and impartial. ;^)


Facts are there to see, members just need to look at Bills (Grannyring) statements here and over at the Lightspeed forum, it's not hard see what going on.
I'll leave it at that.

Cheers George

I've moved on to the newest fad, passive amplification. It's great!! There's no amplifier like no amplifier!!

All you that thought passive line stages were the end of the road are wrong, just wait until you add passive amplification to the loop. No more power cords needed....period!

Wahoo!!!

And as for your little dig.

BTW: Wahoo!!!! Passive amplification???
Now that's an oxymoron, so was your above post.

Cheers George
My comments are well thought out, honest, and my experience. It does not line up exactly with yours so I am somehow flawed as a poster according to you. I don't know why I take your bait? Perhaps I am hopeful of a nicer, more reasoned side of you.

For those interested, the LSA is very, very good with my DHT 845 amp. I am liking it more than ever with this amp and my current speakers. My past experience with the LSA has always been positive and my detailed posts reflect that fact on the LSA thread. But, currently it is exceeding my expectations and the second best "preamp" I have had in my system. More to come with further listening and time.
Bill (Grannyring)
Your credibility and honesty are well recognized on audiogon. Common sense dictacts that some will prefer passive and others active line stages, it just depends. I don't understand the put down comments for those who don't find the Lightspeed(or passive/direct source) right for them after an audition in their system. It comes across as petty.
Charles,
Great detective work George! You must have much free time on your hands down under. I'm too busy to comb through your replies, though I'm sure they are all business related.

Obviously, either my moniker was highjacked, or I was high at the time. The time frame is what throws me, I would have guessed that all of my passive experiences were well before 2005. Too many toys, not enough time nor money.

So now you have Bill backed into a corner. He either has to come out and say your LSA is awesome, or you can come out and say "I told you so".
It's a win-win for you. Well played George.
George- It's call hyperbole:
hy·per·bo·le
hīˈpərbəlē/
noun
noun: hyperbole; plural noun: hyperboles

exaggerated statements or claims not meant to be taken literally.


Your right Swampwalker.

My aim was originally trying to get the OP of this thread to do, was to go direct with his PS Audio DSD into his amps, with no any mention from me of my own product.

Others seem to like to bring it up as a target. Being 6'2" 240lb I don't usually back down from much, but to save the OP's thread I will cease any further retaliation.

Cheers George
I am 6' 4" and 215 with a shaved bald head that makes me look a little reptilian. That may cause very few to back down!

The Lightspeed is indeed one of the very best buys in all of audio. In my current set up I can find very little fault and love the unit. In fact I liked it so much I decided to try and make it work even better in my rig.

I removed the LSA from its chassis and inserted the board directly into my Yamamoto dac. Yes, the output of the dac feeds the LSA board directly using very high quality silver/gold wire. I bypassed two sets of RCAs and an IC this way. I then mounted the volume control to the front of the dac.

The sound is nothing short of outstanding and pure. The dac is solid state and stays at room temp at all times so the LSA components are always happy.

So I now have a wonderful Yamamoto dac with built in LS Attenuator.
