Thanks for both comments. Very helpful. The Audio Research ls5 mkii has Input impedance of 200K ohms balanced and Output impedance 400 ohms balanced Main (2), 20K ohms minimum load and 2000pF maximum capacitance. From what I think you're saying that ARC could work, right? Laurence
Does a tube preamp warm up sound of SS amp?
I'm thinking of getting a SS amp for my Mag 3.6's to get the power I think I need. Would a tube preamp sweeten and warm the sound? I'm leaning toward a Bryston B4 SST2 amp (but nothing definite yet). Any ideas for a tube preamp that might work with it? Are there any conflicts that I should look for with a tube preamp and a SS amp? Eg, impedance issues, etc? Thanks so much for your help. Laurence
