I have had the opportunity to have had the V5-xe as well as the V1-xe in my system. What has been said about the bass of the V5-xe is more or less true. But, if you have never heard you own set-up with an amp that provides better (deeper/solid) then you will never know that what you get out of the V5-xe isn't as good as it might be. I myself found the bass response to be quite adequate. It drove my KEF Reference 201/2 to a bass performance that you would think is not possible with these stand mounted speakers. As well there are many other glorious capabilities that the V5=xe brings that are fairly lacking with other amps. For instance the soundstage it throws is wide open, deep and well beyond the speakers. It's like you could walk around the soundstage and in between the layers of instrments. Plus the venue ambience is shockingly clear to the point you could almost run and touch it behind the players. The sound is so detailed as to be superior to any other amp save one that I have had in my system. Not the Cello Encore 50 mono-blocks they being at the bottom of the pile. Then a Parasound 23 nice little amp easily outdid the Cellos (to be fair to Cello these are a pretty old design by today's amps0 Then I got a Pass x150.5 this sounded quite good for a number of months. Oh by the way before the Pass I had a pair of Channel Island Audio D-200s I really liked them a lot (I hung on to them) and they gave up very little to the Pass. They have now been reddesigned to be even better as the MKII. I sure would like to hear anyones comment on listening to this new MKIi.
So after much thought I wanted to give a listen to the Ayres, Asthetics Atlas amp, MBL 8100M, Burmester 036 bridged, ViTUS 010 integrated. About the time of my quest I helped a very dear freind procure an Ayre V5-xe. He had been looking for one on my recommendation. I told him I had never heard one but suspected it would be quite good. He went on vacation and I told him I would keep watching A'gon for one. It wasn't a day later than one came up at a fair price so I grabbed it for my freind and it was shipped to me about a day before he arrived back home. I had deboxed it but didn't fire it up until he was with me ready to listen. No doubt about it. It instantly blew the Pass out to a listing on A'gon and started looking for one for myself. As luck was with me I found there was already on listing a V1-xe so I grabbed it. What a monster 100 lbs + and no place to grab on to it. But, so what. This V1-xe sounds similar in some ways to the V5 but EVEN BETTER. There is no doubt about the bass response, the soundstage is even more delineated, it's got AIR. And, top to bottom not a harsh bone in its body. It drives the KEFs to even greater performance. And by the way these KEFs are also AWSOME. I have the stands packed with in excess of 75 lbs each of metal shot which got very expensive just before I needed it. It was up from like $25 to in some cases over $60per 25LB bag. I'm thoroughly convince that I cannot find any other amp save the Ayre MX-Rs that would tear me away from the V1-xe. It's Awsome and I couldn't be happier with it. I too talked to Steve at Ayre and he concurred that it a great amp. He used to own one before the MX-Rs which he now owns. of course he is a company man but i would say the same things about Ayre's two fine amps. Possibly among the best going. The rest of my system is a Esoteric X-05 SACD/CD Player and I substituted their specil feet that perform poorly with Ceraballs (3) which brought it to life like you can't believe until you hear the difference. The Ayre V1-xe sts on a Stillpoints Component Stand with Stillpoints top and bottom. Again the improvement is dramatic. I use a Music First (passive) Magnetic preamp MKII which just came out. You do need to cover ALL the inputs and outputs with covers (like Cardas sells) All cabling is MIT which I had never used before now and am very happy with it.although I intend to upgrade to better MITs. Well if this hasn't bored you to tears your as crazy as I am.
