Cheap is relative - but new inexpensive Jolida 1501 or used Acurus DIA 10. I have seen some GREAT deals on Ebay for Hafler 9505 which has gobs of power and I think a great sounding amp. You will have to add a preamp to the Hafler. Good luck.
Cheap class A intergrated power.....
Looking for best buy intergrated that could drive a 4 ohm load...new or used...older Musical Fidelity?
