Accuphase E-560 versus VAC Sigma 160i

I *think* many prefer the Luxman 590AX over the Accuphase E-560 is due to cost. The 560 is considerably more expensive... But yes. the Sigma 160i seems to be very well received at every mention.

How much warmth do these three amps have? Which has the most and which has the "best" bass?

A most timely thread for me to observe as I'm in the market for an integrated amplifier such as the VAC Sigma 160i. My Salk Signature Soundscape 8's are rated at 87db sensitivity and a fairly flat 4 ohm load.

My research so far tells me that the Luxman, Pass Labs and Accuphase are all fine integrateds but lean towards the warmer side of things. The VAC is supposedly quite neutral and provides plenty of grunt to be able to provide deep textured bass and dynamics, while keeping the airy finessed highs that good tube amps offer.

I hear ya Beatlebum, but most I have run into or read just purchases one without hearing the others but say they are very happy. I have been trying to get a good read on these offerings for a couple months. What little is out there is inconclusive on the sound character front --other than VAC. One can find good explanations of their sound.

I left a message at an Accuphase dealer in Chicago a few days ago... not heard back yet. Not that great for business when someone is calling from another state asking about the most expensive integrated a company makes...and no call back!

Was emailing with Kevin of VAC too. At least I thought I was... No response to my second message now.

Good way to whittle it down to Luxman I suppose... Actually this is not the first time this has happened to me. I dont know what I am doing wrong but BPT and a few things sold through Tweek Geek got taken off my list last year due to not responding to queries...and in this economy. Whatever!

Kevin may be hard to get ahold of because he's so focused on product design and quality. But when you do get ahold of him in "realtime" communication, on the phone (or in person), it's worth your while. And email chains can be hard to keep going with some folks (guilty, here).

Do you want the head guy at an audio company to act more like the head audio/engineering geek, or the lead salesman?

I sold my VAC pre and don't currently own any VAC gear, but the (factory modded/upgraded, so not quite the average unit) VAC Sigma 160i at my friend's shop sounds so ridiculously good -- neutral, musical, effortlessly non-fatiguing (paired with Magico S1) -- it occasionally makes me think twice...and I've got 200lbs of tube amp with 60lbs of tube preamp at home. I've be very surprised to find better sound than the 160i in a similar package.

Also, while I like my current line stage at least as much as my prior Renaissance III, I'm still reeling from the loss of the latter's built-in phono stage. If you have vinyl, those VAC built-in phonos superb.

Jriggy,

I did personally speak with Kevin Hayes at VAC last week. A very pleasant and informative fellow. Not pushy and wished me well in my integrated amp auditions/searches and he hoped to be welcoming me to the VAC family soon. Don't hesitate to call him.

Mulveling,

Thanks for your thoughts and comments regarding your experiences with VAC gear. I've spoken with a couple of other owners and they echo your impressions.
