Accuphase E-560 versus VAC Sigma 160i

Keithr,
Interesting that you found the Luxman 590ax to be way overly warm. I have not read that about the unit in any reviews (I know, take all reviews with a grain of salt)... Is it possible that the FETs in the amp were not broken in yet. I had a Mosfet amp once and it took quite a while to 'wake up.'
Did you have any other warm character cables or gear involved as well???
Thanks, Just trying to get a barometer going.

Jriggy- The Luxman was a demo piece that On A Higher Note circulates around the country when requested. It definitely had lots of hours on it (and I ran it continuously for 5 days- a space heater!) as the dealer and I had scheduling issues. Two other audiophiles and myself thought similarly on sonics.

Zu speakers tend to favor a slightly warm amp, so I thought it would be a perfect match. That was not the case however. I have another Class A amp (Valvet) in the system currently that sounds much better. I was told to demo the Luxman AB integrated as it's less warm, but I wasn't really interested.

The other integrated you should probably audition is the Ayre. It sounds quite good on some systems. I think Ayre, Dartzeel, and Vac would be my audition. Dart imo is the best, but at 2x the price.

Thanks Keithr. Very helpful.

I have owned the VAC Sigma 160i with built in MC phono stage for about 2 years and continue to be impressed with its sound and build quality as well as the support of Kevin Hayes and company at VAC.

I find it to have a beguiling combination of the liquidity and dimensionality people like from tubes along with the resolution, drive and bass control that people typically associate with good solid state.

For me it is the cornerstone of a high quality, but simplified system and I would highly recommend an audition for anyone in the market for a great integrated at that price point.

I have not heard the Accuphase but I have heard the Luxman Class As, Pass Class A, older ARC Vsi50, various Mcintosh, older Ayre and many others, and still preferred the VAC by a pretty good margin for my tastes (classical, jazz, blues, acoustic, some rock, etc).

The new Ayre 5 series integrated has a nice sound as well and the Vitus at a higher price point is also a good sounding integrated that would be worth consideration.

I own the Vac 160i for about 6 months now. It is a fast and tight amp. A powerful tube integrated amp. Much more like a solid state IMHO.

I have another set of tube amp, the legendary BAT VK60 with ARC ls17 preamp. They just sound sweeeeeet and warm. sweeter and warmer than sigma but not as powerful as the Sigma.

If you have sensitive high db speakers like Tannoy, avantgarde, you can try BAT VK60 amp if you like speakers like magico s1, wilson or revel, VAC amp is a better choice.
