Most neutral pre to use Stereomour II as Power amp

[DPetrini]

Still enjoying big Time stereomour II. Will soon add a dac with much lower output voltage and the Need to increase gain Will became a reality. Is the beepree2 the inique choice(Will Need to save before buy) or the moreplay might be a choice as well? What Is the main Sonic signature of the Two when compared? Bottom line,Will the moreplay increase gain in my system succesfully or Will i get a decrease of the stereomour sound quality ,unless i use a beepre? Thanxs

How much gain do you need? Can't really answer this question well without knowing. What is the peak output voltage of the DAC?

[DPetrini]

Dac Is 2v compared to actual 2.6. Speakers are 88db and i estimate i Need 6-9db max gain extra compared to today

Probably you can calculate Better based on 2.6 vs 2 Volts dac out

The gain of the Stereomour is about 8x, and 3.5W into 8 ohms is 5.3V.  You will want a minimum of 0.7V of signal going into the Stereomour to push it to full power with the volume control at maximum.  I do not think you need a preamp.  You can grab a little bit of extra gain by bypassing the cathode bias resistors on the 12AT7s if absolutely necessary.

Thanxs for the encouraging response. All the best
