VTL Siefried vs Audio Research 610T

"Dave Wilson is running Siegfrieds with Alexandrias in his home. AFAIK his previous amps were Lamm ML2.1. Call John at Wilson Audio and ask - he knows David's sytem very well."

that's correct ....BTW, they still use the Lamm ML 2.1 in the sound room at Wilson Audio.

I owned the precursor of the ARC 610T ( the Ref 600 Mk lll) which was a very good amp but IMHO the Lamm ML 2.1 is a better amp. I had the 610T on oreder until I heard the Lamm 2.1 and I was smitten. The mid range and upper end is so much better than the ARC ( I still have an ARC Ref 3 which I feel is the best preamp on the planet).

As for the Lamm ML 2.1 I have now the distinct privilege of having heard his new ML 3 which makes the Ref 610T, Sigfrid and my ML 2.1 look like mere pretenders to the throne. My close friend has a pair in his home for loan from Vladimir and I will have the opportunity to play them this week in my system which also consists of X-2 Alexandrias. Stay tuned

BTW to the original poster the ML 2.1 with the MAXX ll sounds superb.
Have a read of Marc Mickelson's review of these amps with his Maxx ll's

Elberoth2,
With regards to the original thread question and my answer, my affiliation had _nothing_ to do with my opinion. I simply shared first hand experiences that were in no way related to our business. In threads involving our products, I contribute merely to correct misstated facts or false assumptions, and _always_ announce my position. Your comment implies some furtive motive or thread sabotage. I can't imagine why you saw that as somehow relevant enough to bring up here.

I have been following this thread, and am curious of one
thing. This is directed for Jon p, and there may not
be an answer here. I know you have mentioned the objective
of wanting to increase your power and headroom here. Is
there anything you are looking for from the VTL from a
sonic standpoint that you may prefer to the ARC. That said,
at this price point I would also want to hear the competition.
FWIW, I have VTL 750's. I am now looking for a slightly
warmer, more textured midrange. I am considering going to
KT-88's to achieve this. I am not sure this helps now.
However, I believe VTL offers their amps w/ a KT-88 option
so this could come to play at some point. My comments are
based on tetrode mode only.

You will find KT88's richer in the mid to upper frequencies, you may lose some lower mid and bass structure, it is a trade off.
