The Onkyo Integra M - 504 is rated at 165w @ 80hms 300w @ 4 ohms conservatively. This Amp is well made and heavy at 50 lbs. It features a dual mono block design. The M 504 is highly prized both for it's vintage look with two large display meters and some of the best technology you will find any amps in this price range. Made in the mid 90's, the specs are impressive and the sound is uncolored. THD .0003% at rated power. If you are looking at these you are looking for quality units. I have 3 sets, I am only selling one. The matching Onkyo Integra P 304 preamp is a highly regarded preamp with excellent features for recording and is made to pair with the M 504 amp. It matches the Onkyo Integra M 504 looks and compliments it in every way. Please note the pictures include a top of the line EQ-35 which is not included in this offer. Price is firm
