I should state that I agree with the gain issue given digital component output voltages. Two volts seems to be the minimum. Too many amps with far too low a sensitivity rating. I have a Line Magnetic integrated which is 0.2V sensitive. Even in triode mode at 15wpc driving Tannoy Sterlings (91dB, 8ohms) can't get past 9 o'clock in my 12'x15' room.
Low gain preamp options
I’ve read lots of preamp suggestion threads and discussions on amp matching. I don’t know what percentage of people have digital only systems, but it seems like there is a missing niche for preamps.
Most DACs have at least a 2V output which exceeds the input sensitivity of most amps. So unlike a phono input there isn’t a real need for gain in most cases. The problem with a passive preamp is some amps don’t have high enough input impedance. Also a preamp allows longer cable runs (if needed). Then there’s the whole tube warmth or tone that some people are so fond of in taming perceived digital harshness.
I’ve read about lots of tube preamps, but even the low gain ones are still in the 10dB range. It would be nice to have a useful amount of volume adjustment instead of silent to too loud with just a wiggle.
The only unit that comes to mind that’s even close is a Schiit Saga+, but it seems like even mid-fi systems should be able to do better. Don’t get me wrong, I’m using one now. It’s great for $400, but at some point it’s going to become the weak link in my system (if it isn’t already).
List of desired features:
<6dB gain
<500 ohm output impedance
tubed output
at least 2 sets of outputs
balanced in/out optional
Anything out there that fits the bill?
