Some very nice suggestions above!
I'd think about a Harman Kardon 430 (only 25 watts x 2) but what a 25 watts. Twin power supply, two filter caps per transformer (so four), decent phono stage, good heft, and warm, warm, warm! Very musical.
I have no idea how it would sound paired with A.J. towers though? But my experience with the A.J. bookies has been that they sound good on almost anything and very very good on some things!
Happy hunting.
I'd also highly recommend a JVC R-S33 which can surely be had for much less than 100. 40 watts by 2. Should have no problem whatsoever driving your towers!
