Great MOSFET amp
This amp sounds great. It is a MOSFET design. So not your typical bipolar amp. Yes, it runs very warm, and it does take about 10 minutes to come to full operating temperature. Worth it tho. Sounds much bigger than the 80W/ch. @ 8 ohms would suggest, and it has a lot of power depth. Sports a dual power supply, one complete one for each channel. Toroidal power transformer = fast response. Double output FET's means plenty of safe operating area, so no problem driving 4 ohm loads. I have used it driving a pair of AR 2AX's or a pair of ELAC UB52's both to great effect and satisfying levels. Amp really surprises at the detail resolved. Where are you gonna get that performance under $300? No where. (I feel this amp is a perfect match for those UB52's. The UB's are 6 ohm, so it's like a 100W amp with tons of reserve driving them. Yummy.)Vollständige Rezension lesen

Good value for repair and rejuvenation
I like this generation of Adcom MOSFET amps.
I buy inexpensive ones that look to be in reasonable cosmetic condition, but need repair. As usual this had one channel out, and I replaced the outputs on that side. The output MOSFETS, IRFP240 and IRFP9240, and drviers are still available and relatively cheap. or you can buy pre-matched outputs from diy audio store and other individual providers.
I also replace all the electrolytic capacitors. The main ones are 10,000uF nichicons at 85 degrees, and I can find longer-lasting higher-capacitance 15,000 or 18,000 rated at 105 degrees for about $15 each. I could buy a working model for about twice as much, but the recapping is the expensive part of the repair.Vollständige Rezension lesen

clean power
This review is for folks who have never owned Adcom products. Those who have don't need any encouragement. Adcom is a solid audio company with a history of high quality components. Their amplifiers are very powerful w/ no discernible distortion. That means you can count on them to produce crisp, clean sound without putting your speakers at risk. I own the 5500 & 5300 & they are extremely reliable. I highly recommend these products.Vollständige Rezension lesen

It's hard to go wrong with Adcom power amps.
This amp has a nice clean sound and plenty of power. It's a heavy amp, which for me is a sign of big heat sinks which tend to make amps last longer.

Better than any PA currently in the market up to $1,500.00
After full re-cap and PSU full upgrade, become one of biggest bargain on Hi-End amplifiers. Better than any $2,500.00 PA in the market nowadays.
