its good to be able to join the group again! Been awhile since last entry, one computer crash, one ruptured c-7 disk,and required repair, and L.&R. c. tunnel repair! Hell of a way to start 2011. Anyway i wanted to pose this question? I've been obsessing over a tubed pre. for a while and decided on an AE 3 MKll. Then i found a Rogue audio 66 4sale. since i've been trapped at home 4 far too long i've split my time following you guys and sitting in the stereo room, both of which have brought me to the conclusion that my room needs a preamp, and i need the vast knowledge of the group to make an educated decision. Now that i've been a member and read many posts and threads on many subjects, i realize how little i really now about our hobby! What i was wondering is about the output and input empedence. I know it's important, and don't know whats right. Any help would appreciated! The AE-3 has an output emp. of 560 ohms, input emp. of 100kohms. The Rogue 66 has an output emp. of 650ohms & and no input listed. The two are well apart on price, and the Rogue is used. My Parasound amp has a rated input emp. of 33k ohms and input sens. of 1v 4 28.28v output. which way would you guys go if any at all?
 
To tube or not to tube

slowGEESER, Currently using a Parasound hca 1500a, which i like alot, but would like to have more controll via. preamp w/ volume controll.
 
I was looking for a tube pre agile back as well and had the same questions. My sunfire amp was at 40k ohm I do believe. I was considering the prima Luna but the dealer said the impedance was too low on the sunfire and that this would be a bad match. So I went with the Cary slp 98 which is said to be able to work well with amps such as ours.

I started a thread about this very topic and somebody actually gave out a formula. I'll see if I can find it
Edit:
the name of the thread was Tube preamp with Sunfire amp. Also my sunfire is only 24k ohms. Sorry I couldn't paste the link with my touch and I do not believe I started the thread either!!
