musical,I used to own audio research preamp,and heard
tube preamps.And Joe is a very nice person to deal with.

Morning :-)
so i auditioned EAR 864 yesterday. What to say. Difference between Accuphase---EAR---Electrocompaniet and Accuphase---Electrocompaniet was not stunning. At first sight everythin' kept the same. In a while I noticed that sound without EAR became less natural and less involving.
Also EAR added sweetness so i would prefer to keep that natural and involving impressions but subtract sweetness.
Anyway now i am convinced that good preamp won't spoil my system synergy.
To say the truth my first candidates are Sonic frontiers, Aesthetix Calypso and Belles 28A ref (up to forum discussions they got mostly positive feedback)

Also EAR added sweetness so i would prefer to keep that natural and involving impressions but subtract sweetness.

Check out ARC LS-25MkII.

At least consider the Einstein. With NOS tubes, it is world class and very reliable.

Snakonmars,

Don't forget you can always tweak the sound by using NOS tubes. Then you can look at Interconnects and Power Cords for the preamp to help refine the sound. But your tubes will have the most impact in sound refinement.
