Valve amplifier recommendations!

[jazzy]

Hi Folks,

I'm a new member, I've just introduced myself in the Welcome area.

I used to have a Rogers valve amp when i was a kid (yes i'm that old!) and many years later i find myself wanting to get another Valve amp.

I've been slowly bringing my system to the point where i can introduce one as a 'test' against my current solid state amp (a Sonneteer Orton).

My current setup is: Well Tempered Amadeus, Sonneteer Sedley phono stage, Sonneteer Orton, Audio Note AN-J.

Most of my listening is Jazz and acoustic music.

So far i've been thinking along the lines of:

Audio Note OTO
Icon Audio Stereo 40.2 Mk III
Unison Research Prelude
Audio Innovations 1st Audio
Leben CS300X

My listening room is an attic room and fairly narrow but long!

I've seen good examples of all of these amps currently for sale in classifieds or with dealers.
Auditioning them is difficult though!

My budget is around 1.5k but could be more if I decide to sell/trade the Orton.

Any thoughts/experiences with these or other valve amps would be gratefully received!

thanks in advance

Nick
