Since Krell 302e & Cary SPL-05 have (gain/imp issues) what tube pre is best w/ the krell?


Looking SS enhanced sounstage,bass slam plus the warmth of tubes.

What gain/impedance issue?
John (Jmcgrogan2), see my posts in this thread.

There is no issue with gain, although the gain specs of the SLP-05 are very inconsistent with John Atkinson’s measurements. As is the output impedance spec, potentially with greater significance. However as I said that thread:
In themselves none of these things should matter with the Krell amps that have been mentioned, given their very high 100K unbalanced and 200K balanced input impedances, and their moderate specified gains of about 25.5 db. However after noting some oddities in the measurements JA concluded by saying:
Though it has some anomalies, such as being happier with 10k ohm loads than with 100k ohms, the Cary SLP 05 offers respectable measured performance from its unbalanced jacks. I was a little disappointed with its behavior in balanced mode, however.
Which is not to say necessarily that the combo wouldn’t work well together, but it seems to me that there is cause for concern.
