Cary slp 88 with McCormack dna 125?

Thinking about buying a cary slp 88 for my dna 125,im useing monitor audio gold ref 10 speakers with rel strata 3 sub and fmj cd 23.
The components that you are asking about are a little newer than mine, Cary SLP-50B and McCormack DNA 0.5, but IMO a tubed preamp is great with a McCormack amp. As a matter of fact, a Cary SLP-50B just came up for sale on Audiogon today (not mine), it may be worth checking into.
Check the output and input impedences...
