Berkeley Alpha Reference run direct


Has anyone found a preamplifier that improves the sound from a Berkeley Alpha Reference DAC? If so, what preamp? Mine sounds amazing feeding my amplifiers direct, DAC to amps.

Joeinid - In your opinion with the AR Ref 6, is the preamp super highly resolving, and thus makes imperfect recordings sound just that way, imperfect? Or is it distorting the signal somehow, resulting in the forward soundstage and punchy on-steroids feel?

The Ref 6 is NOT distorting the signal. It just doesn't let a bad recording sound good. It lets it all through, good or bad.

I have not heard the ARC Ref 5SE recently, but it's more forgiving and probably not as resolving compared to the Ref 6 (check the thread in the amp and preamp section).

I am personally thinking about the Ref 10 or KX-R Twenty to go with my MX-R Twenty amps.

I have an Ayre K-1xe here now. I have to strain and strain and switch back and forth and back and forth to hear the very slight differences between the K-1xe in circuit and run directly from the BAR. The KX-R Twenty would likely be a step or two above even that.

The sensitivity adjustment is explained under the heading "Left & Right Gain" on page 3 in the Preliminary Quick User Guide Software Rev 1.00.
I guess I don't understand their explaination. It this not just setting the output levels, by left and right channels, in .05db steps? 
If I normally run a volume level of 47.3 on Diana Krall Live in Paris, for example, how would I change things to get the same volume level, but higher resolution?
