Well I remember when I bought a Goldman Memesis3 they told me not to use it with a CAT pre; because of the dc-off-set---whatever the hell that refers to. Anybody comprende dc-off-set??
Specs to look for when matching tube pre to SS amp
I would like to not make a costly mistake and learn how one determines (at least from a specifications standpoint) on how to match equipment. I have a deHavilland UltraVerve tube preamp and am looking for a new/used SS amp. The Dehavilland specs are:
Input signal: 2v RMS maximum
freq respon : 10Hz to 80kHz
noise : <80db
Max output : 8v RMS
Gain : up to 10db
The pre only uses single ended inputs and I want to match to a SS amp. My monitors are Focus Audio FS688 (85db) so I am looking at amps in the 200+ wpc range. Someone told me that I should go with an amp that has no more than @ 1.5 input sensitivity. Some of the amps that I'm looking at, GamuT and the Classe CA 2200 are in that range. I would like to consider an amp like the Blue Circle BC26MK2 as I have read it sounds somewhat like a tube amp and matches well with the Focus speakers, but it's input sensitivity rating is 4.48 to 200W. Would this create a mismatch? I believe the Pass Labs .2 series is also well over 1.5 . I do not often listen at loud volume levels. Is there more than amp input sensitivity to consider when matching to a tube preamp? I can not demo a lot of equipment, but would appreciate your suggestions. Thank you!
