Hey B., I was about to ask if the Yamaha C-70 was among this upper echelon. That thing was MSRP'd at over $700 if I can believe what I read. I don't use the phono, but what is the preamps actual contribution to the sound character? It is not the source, and I like the tone controls "flat" or out of the circuit most of the time. -sfbully said:My favorite has been the Yamaha C-80, a superb control amp by any means. I am also very fond of the Carver C-1, a definite overachiever. The Kenwood Basic C2 has a great phono section, as good as any. I have a LOT of fun with the big Soundcraftsmen DX4200 pre/eq rig..
hi, i am not at all familiar w/this pre, but if you're talking 24vdc, an excellent upgrade would ba a lab grade power supply from hewlett packard, lambda, etc. these things are literally pennies on the dollar on ebay; yust look for one w/the required amperage rating, & one that adjusts to 24vdc. i used a ~$2k hp unit for the motor on my turntable, (picked up on ebay for ~$100); it made a worthwhile improvement.Beobloke said:Mine's this one - Quantum Electronics 102.
Nice and simple - inputs for turntable, tape and aux, volume and balance control and that's it!! Switchable internal sensitivity for the tape and aux and plug-in matching boards for the phono input that you solder components onto to exactly match your cartridge's output level and required load impedance/capacitance.
Takes +/-24V power from matching power amplifiers or a stand-alone PSU upgrade (still havenn't find one of these to match it yet, though!)

Great phono section, and more power supply capacitance than a typical 100WPC amp of the time (their claim, not mine). Since Bully gave the OK for modern gear as well, then I'd have to say my current preamp is my fave, the Theta Casablanca.
I'll give an honorable mention to Crexrun's Technics SU-9070 as well, very nice preamp.
I don't think RGR lasted too long as a company. RGR stands for Robert Grodinsky Research, so I typed ol' Bob's name into Google and got this link to a page with some info on him. As of 1999 he was still churning out patents, so it appears he may still be involved with audio.WhiteSE said:I have seen an amp from RGR at a pawn shop in atlanta,,,and I think a friend of mine has the Preamp....interesting them RGR...do you have any info as to what happened to that co.?
