I would recommend Conrad-Johnson PV5 pre-amp & MV-50 power amp. The combo is VERY MUSICAL! They were produced in the mid '80's. New around $3000, should be able to buy for $900-$1200 now. PV5 has only one phono input, but what a phono section! Amp is AB, but is a very powerful 50 WPC. Very highly rated in its day and very attractive ergonomics. Still being seviced by CJ: parts, tubes, upgrades, boxes, etc.
