I'm not dated- its just this joint thing that keeps reminding me
of "I've seen better days".

I stated that I wanted to keep using the tubes cause I like the sound with my speakers. I've heard ss amps and really like them and still have an Altec 9440 with balance in and outs which I'm gonna try with the 990, thats on the way.
My speakers are 94.5 db @1watt@1 meter to work with tubes-just about all tubes at that rating. I've had 7591s in my mac for several years now and they still test strong with the amp used daily. Its not unusual to find 60's amps with original tubes-at least the driver and preamp sections. Anyways my first tubed thingy was an Admiral (phono/radio) grandma's gift to me to get that old thing out the house (gramps got a SS stereo in other words)-mid to late 60's and was used to listen to Beaker Street and heat the room on cold nites--now hows that for dated.

Looking at your systems do you have two 990 preamps or switch between the 7700 and 755 crown with the one?
