Adcom - A Good Value?? Auctions risky??

used B&K EX442 can be had for ~$400-$500 used. It smokes the Adcom...

As I've commented before in these pages, the audiophile community tends to disparage some of the entry level, yet high-value products, available from various manufacturers. Adcom belongs to this "Rodney Dangerfield" group -- it tends not to get much respect. However, you will find that many of the regulars who contribute to this forum have owned Adcom preamps and power amps at one time or another -- myself included.

Unlike some of the other contributors, I have also been a retail salesman for Adcom equipment. Adcom has had some QC problems in recent years, which began after they shifted their manufacturing from one of the high-quality assemblers in Taiwan to a facility in mainland China. Having said that, I'd also say that Adcom seems to have addressed most of those problems, and continues to do a a pretty decent job of continuing to design and sell solid products for fair prices.

Based on my experiences with Adcom amps, which involves a LOT of listening hours with various speakers, I'd say that a used 5500 power amp is a hell of a value. For around $650-750, there are very few amps that provide 200 wpc of clean signal, and will handle speaker loads as low as 4 ohms with aplomb.

I am less enthused about the 5802, not because it's performance is poor (it's performance is actually quite good), but because it has a lot of competition at its price point. As Sean noted above, the 5802 is a better amp than its predecessor, the 5800. It is still, however, a very large amp and it produces a lot of heat for a solid state amp. It thus requires a lot of space with good ventilation.

I have both bought and sold Adcom power amps on Audiogon and E-bay, and had good experiences in all instances except one (a dealer that slightly misrepresented the exterior condition of the amp, tho' it worked fine). If you make a point of talking -- by phone -- with the seller, you can usually get a better idea about the fairness of the deal. You should also check seller ratings, since a lot of good feedback is usually a sound indicator of the seller's honesty. Also, Audiogon has "verified members", whose addresses and credit have been verified.

My complaints about Adcom is the cheapness of the single ended(rca jack) connectors on their products. I have had two instances where the connector has pulled of of the back of the unit. Maybe my experience is unique. One instance was on digital output of a GCD 575 cd player, the other was the input jack of a GFA555 amp.

I have also owned the GPA565 preamp, good sound for the money. Before buying Adcom new, I would look to buy used from other manufactures....Classe, Bryston etc.

JMHO

I owned an early Adcom 5500 and considered it a decent sounding and built amp. It hummed in my system, but then all amps seem to hum in my system-- it's an electical supply problem in my case. I wouldn't hesitate to buy adcom, but I agree with Abecollins (above), and would look for the smoother sounding Classe' CA 100, 150, or 200. I would put these in a class with McCormack DNA-1 and 0.5 amps-- also recommended. Good Luck. Craig

My experience with Adcom is similar to Sdcampbell. I used to sell Adcom products in a few retail audio stores. I changed professions in 1995. They use to run many contests for retail salespeople and along the way I had picked up a number of their components through these contests. In my opinion, their DA converter, the 600 model at that time, was a great buy at its pricepoint.
Their amplifiers and preamplifiers were solid products that had few mechanical issues. The 555 amplifier sold itself. I found it to be a bit harsh compared to other amplifiers that we sold, but it must be said that those amplifiers were more expensive and less powerful. I am told that their current line is well produced.
I also agree that auctions are risky only if trust between the buyer and the seller is not established. I have had many positive experiences working with Audiogon members. That has been predicated by conversations either by phone or on the internet with buyers and sellers before committing to sales.
