Thanks, guys.
I know this hobbie is complicated ... I was hoping the DC-1 DAC sound to be at par with Gungnir, never mind Bifrost, according to several reviews in this forum. Did you compare both as direct DACs? In my view the pairing of DC-1 and Bifrost may have given it an unfair advantage.
I also know tastes and ancillary equipment have an effect in the perceived end result. This is what is making the whole thing hard for me to decide without auditioning feasibility.
The argument about the preamp's low gain making the power amp 'bright' is one I don't follow, as I would expect it to make the sound 'leaner' (less body and weight, mainly affecting lower frequencies' presence) since the power amp would dilute the preamp's gain. Maybe this is the sensation you're referring to with bright?
In any event, I run an integrated amp with its own (high) input gain, so I would imagine the built-in preamp in my integrated would amplify the incoming DC-1 preamp's signal. But, the preamp needs to have some reasonable output gain range for me to be able to 'ride' this gain with my amp. For example, increasing the DC-1 volume and decreasing the amp's volume would conceptually provide more weight and body to the sound from, say, shallow or lean recordings.
I asked this same 'riding the gain' question to Keith Levkoff at Emotiva, and he said I could certainly achieve that.
Man, I don't want to go to square 1 again! Sorry!
