Looking for suggestions, especially from those driving a DAC4800A or Cherry amp...

I have the Atma-Sphere linestage only version of the MP-1, called the MLS-1 and really like it.  It is truly differential all the way from input to output.  Various other balanced pre's are available from BAT, Audio Research, Modwright (LS36.5).

You know what I'm gonna say  :wink:  but for other's who might be interested:

I've used my VAC Standard MKII with probably all of your amps, and it has always been a superb match.

There is quite a bit of gain, though, so I can only use maybe 25% of the volume knob rotation (except if you come over, than it's 35%, or 40% for Raves  :rock:)

Until I bought a Cherry JR, I was reluctant to invest in XLR ICs although Tommy had been loaning me amps in order to sink the hook. I did borrow some Tara XLRs for my last Rave and the sound was excellent. I bought some IXOS XLRs from Shane for cheap, and they sound much much better than with any combo of RCAs with adapters I had tried.

Don't know if that's the preamp working better, the lack of adapters or the amp being fed what it "natively" wants to see, but I'm not complaining.

You have it right with the BAT 51SE (2 xlr).  It is also a dual-mono topology.  Just an fyi.
