VAC owners, sound off


I've got my eye on a used VAC preamp here on agon, but it's over 9 years old. A phone call to Kevin Hayes was helpful, but he's not exactly unbiased. Anyone care to chime in on their experiences with VAC gear over the long term? thanks

I presume you are looking at a Standard Pre since a few ones are available right now. I had an LE model for the last 9 months. While shopping, I had a chance to listen to a VTL 5.5, an Aesthetyx Calypso, a CJ Premier 10 and a CJ Premier 17. All of them were equally fine units (depending of your musical taste) in about the same price range (on the used market). I finally chose the VAC because of its overall sonic presentation and value/price ratio with a phono stage, which was an advantage over the other units.

A technician had a look at it recently, by curiosity because he heard about the brand but never seen one before, so he asked me if he could look at it. He was very surprised at the quality put into the fabrication of the preamp. He told me I had a "point to point" preamp (go figure what it means but from what I understand, more handcraft is involved with individual connections instead of boards)which is a sign of much higher quality. Supposedly very rare especially at this price point.

Now, it is a very transparent player with a forward presentation. Imaging is its stronghold but it is not as involving as other units, unless you experiment with some tube rolling. After following "Joe's tube lore" recommendations, I finally tuned it to my taste and came to fully enjoy it. But it has to be carefully matched with the other components.

Strangely, I recently replaced it by a CJ Premier 16 MK II that suddenly appeared at a price nobody could have a second thinking (recession sometimes has some advantages !). Totally different sounding machine with a tremendous reputation backing it ! I will say this, in my system, the VAC doesn't give an inch in the imaging and is more transparent than the Pr 16. The 16 is richer in the mid bass and generally mellower in its overall presentation. For the moment, there is no way I'm selling the VAC at the price they're going right now. I'll find another use for it !

It Canada, VAC is a not known. I did a lot of research on the net, on Audiogon and the rest and could not find a lot of reviews or comments about the unit. I think this has to be taken into account about its resale value. But for the long term investor, nobody can go wrong with VAC !
Well Tholt,

Anytime you can pinpoint us a tube preamp selling new for 1500 $ that equals a nine year old VAC Standard, please tell us because I'm really curious to hear such a marvel !

In the meantime, I had a friend's CJ PV-15 LS in my system about 18 months ago. A nearly 3000 $ machine of a recent vintage. Forget it ! Simply not in the same league ! Very pleasant unit to listen to, warm and involving. Does'nt come near the quality in the imaging and resolving details in the background.Most noticeably is the dynamics differential between instruments and the capacity to pinpoint them in space.
Hello Tholt,

As told in a previous post, I strongly recommend you have a look at "Joe's tube lore" for good advices on 12au7 and 12AX7 tubes. I went through it and tried many of its recommendations with my Standard LE. Worth it. Just type it on Google and you will fall in Audio Asylum where it is based.

Now, the VAC tubes that come with the unit are....hmmm very so so. Flat, dull and no punch.They will give you a bad impression of your unit, period !

IMHO, Joe's....recommends RCA Clear top 12 in the 12AU7 spot and Amperex Bugle Boy. The RCA'S are very good overall performers and easy to get at a reasonable price. Got a couple of pairs myself and strongly recommend you choose those as a starter. Can't go wrong with those. The Bugle Boys are scarce and expensive. I've got Valvo ones supposedly made in the same factory, at the same time, for a fair price. I love those for the better dynamics and openness.

As for the 12AX7, there is a lot of choice and tried many combinations. My preferred ones are the 5751 like Joe's recommend. I love both the GE JG5751WA and the Sylvania JHS-5751 or Gold Brand. I prefer the GE for rock because of their slightly recessed soundstage with its better detailing of electric guitar. Bass and drums are tight and slammy with this one. I prefer the Sylvanias for Jazz, soft rock and ambient. Very warm and lush mids one with voices very upfront.

GE'S are common on Ebay and Sylvanias quite expensive but damn their worth it.

Good luck !
Happy for you ! Amperexes in the 12au7 spot will bring you back some extension in the highs, decay maybe or maybe not. In my preamp, it did but it is a more subtle difference than changing the 12AX7 tubes. Remember to wait at least 50 hrs of running the new tubes in order to hear the best of them.

You say the preamp has a little less decay than with the original tubes. This means it is there somewhere but hidden since you heard it before. You have more bass and weight, obviously your hearing is rebalancing itself. You might just hear your decay back once you are accustomed to it.

Have trials with your speakers positionning and have a look at your acoustics. Don't forget to check your electronics isolation to vibration. Better quality electronics are more sensible to the surroundings. Doesn't cost anything and most of the time does a lot.

Have fun !
