tube preamp w/ solid state amp

I ran a Conrad Johnson pv10a pre along with a Classe DR-9amp with very good effect with excellent sound while it all ran a pair of Sound dynamics300ti,MGIII,and numorous small british speakers.

The general rule of thumb is the input impedance of the amp should be at least 10x greater than the output impedance of the preamplifier - this is almost never an issue when using a tube amp which genrally, but not always, 100kohm input impedance. Generally only a consideration with 10Kohm amps (some Pass amps for example), but it is said that the greater the differential the better. Ofcourse, theory ain't worth a darn compared to trying it out and "specs" can be misleading and don't always tell the full story.

I am using a McCormack DNA-125 and Manley Shrimp with no problems. Talked w/Steve McCormack prior to buying the Shrimp and he said there would be no problem mating the two but for the sensitive volume attenuator on the Manley which only allows me to turn up the pre to about twelve o'clock.

I run a tube pre and solid state amps with no issues. The pairing sounds really good. Also, no issues with the sequence of turning off amp and preamp.

Tube preamps can play more detail in a relaxed manner than their transistor counterparts. Once lost, you can't make up for it downstream so yes, a tube preamp is a good idea with a transistor amp.

Of course, I think a tube amplifier is a nice move too :)
