Personal Preamp Evolution


I found the the threads on the amplifier evolution very intriguing,the speaker evolution thread as well .I am not sure if there is already a thread regarding preamps.Many of us failed to mention their preamps[myself included] in the amplifier thread.After all, it really is an amplifier per say.

DB Systems
Spectral MS-One
Melos SHA-1
Adcom 750

Prior to the DB Systems, it was all receivers and integrateds.
1. Preamp section of Panasonic Mini-Receiver (found in just about every dentist's office in the early 70s)
2. Preamp section of Pilot 25 wpc integrated solid state amp
3. Preamp section of Yamaha CR620 receiver
4. Nakamichi 620 Tuner/Preamp (Slanted panel with gigantic tuning dial...coolest looking piece of equipment ever)
5. Hafler DH101 kits - several bought, built, modified and sold.
6. conrad-johnson PV3 - bought, built and modified extensively (great sounding unit)
7. conrad-johnson PV2ar
8. Beard P505 - luscious
9. Spectral DMC10delta - wonderful
10. Wright Sound Lab WPL20 - supremo

All have been used primarily for use with phono sources. The last two have been oustanding in this regard. The last is equally facile with digital sources.
