Those considering purchase of a SIT-3 should keep in mind that its gain is only 11.5 db, which is extremely low for a power amp. Consequently it requires a single-ended input of about 3.2 volts to be driven to its rated maximum power capability of 18 watts into 8 ohms.
That is particularly likely to be a problem in applications where it would be driven directly from a DAC, or in vinyl-based applications if an active preamp providing something like 15 db or more of gain is not being used, and of course in just about any application in which a passive preamp is used.
The XA25, in contrast, provides 20 db of gain, which is still below average but should be ok in most applications.
