Ok....Audiogoners: need some tube amp ideas

Any suggestion/comment is appreciated. Just off the top of my head, below is a list of initial parameters.

- budget: $4k ish (somewhat flexible)
- tubes/valves amp(s)
- preowned or new
- mono or stereo configuration
- min wattage: 70 and higher (this rating would afford me more speaker options down the road e.g. 4/8 ohm and >88db efficiency)
- brand(s): leaning toward more esoteric manufacturers or models (e.g. Dodd 120, VAC PHI, Audio Valves); would prefer staying away from manufactueres that do magazine advertisement.

Current thought: I might push the budget a bit to consider a pair of preowned Lamm ML1.

Thanks much. (currently listening to Rachmaninoff Piano Concerto No.2 by NY Philharmonic/Berstein)

I have no idea about the VAC PHi amps, but I can tell you that the VAC Ren Mk2 pre is magnificent with the Merlins.

Kyyuan, I recently heard the Quicksilver V4's mated with Cary electronics and a Vandy Quattro speaker. The Quickies seem to have the dynamics, sweetness, space, 3D etc. Liked them very much.

Swampwalker, can you provide the models of Atma, Joule, and Berning in discussion? I am trying to understand the price:performance ratio. Lots of people compare VZN and MA, but VZN series I believe are more $/watt. I have access to Joule VZN 100 and MA-1Mkii and Audio Valve Challenger 115. The OTL has its signatory floating sound, but the Audio Valve PP design also has its magic i.e. the most realistic bass (growl) and drums (tight kick and snare). If Audio Valve has designed their amps with the feedback control knob, I'd be set! How about Audio Valve PP for bass and drums, and OTL for vocals, strings, keys, woodwinds, all upper freq range.

FWIW Nkj's comments about weight, chassis awkwardness and biasing are red herrings so far as we can tell. This is not the sort of thing I like to harp on but I sent Nkj an email explaining that our amps have been autobias for a while and he denied that he had even made a comment about our amps at all:

Hello Ralph,

You must of intended the info re auto bias for someone else.. I've not posted on audiogon re your amps at all

all the the best,

Nkj

Consequently we suspect he's either not heard them at all or did so so long ago that whatever he has heard is not even slightly current. Hard to tell.

Agree completely with what Atmasphere said. Their amps with autobiasing are simple to use and enjoy. Just hook 'em up and switch 'em on. Initially you want to zero the DC offset and once in a great while after that, but there's no tube swapping involved. The 6AS7 output tubes are good for 10,000 hours' use on average.
