Advent 300


I am enjoying a restored Advent 300 preamplifier. It has had extensive work done on it. I sounds marvelous! The phone section is pretty good. Smooth flat frequency response when I use it with my MM Grado cartridge and turntable. 
Am curious, what amps did you all use with this unique preamplifier when it came out? Now? The advent 300 will let you know quite a bit at least for me when I plug different pieces into it. It rocks super nice with a Nakamichi on the tape input. It plays great mellow sound like I never heard before on my records through the phono input. Unit has all new caps, and other parts inside. Have always wanted one. My system it is plugged into consists of large efficient ADS L1590 speakers (restored), Adcom GP5400, Dual 1249, Nakamichi CR4, 
Thanks for your input.

Thanks everyone for jumping in this discussion. I do have a nice reference B &K amplifier I want to use with it. The adcom is okay for a while. Any other amp suggestions. 
I have not heard the NAD sound I used to like. I miss the hafler sound. It was super warm and nice. The hafler 110 was a very nice preamp also but this advent might be better. 
peter s The tech made it great again, I am very satisfied with the sound. I am okay with the adcom amp but am wondering why I sold my hafler DH 220 a couple years ago, would sound good like you said I bet.
