The typical rule of thumb is that the input impedance of a device should be at least 10 times the output impedance of the device connecting to it. If the Krell has a 47k input inpedance then the Phono preamp should be less than 4700 ohms. This is amazingly high and I don't remember seeing any preamp with an output inpedance even approaching 4700 ohms. You should therefore be OK with any phono preamp that you like sonically. Wally
TUBE or S/S Phono Amp with an all s/s system?
I looking for a phono amp with mm/mc (high output) with better than average gain. I'm using KreLL pre & KreLL amp, cartridge is Grado Reference. I understand output impedance is something to consider when trying to match components...so which way would you go, tube or s/s for phono amp? What specs should I be looking for?
KreLL amp input impedance > 47K
KreLL preamp input impedance > 47K / output impedance 10ohms
I'm quite "green" as far as "tech" talk goes, so I'll be the first to admit that I have a deficiency in this area.
Thanks for your advice,
