adcom equipment.....

Remember visiting my brother in law in 1992 or 1993, in orland park, Il.  A small very nice shop “simply stereo”
ran by two of the most relaxed and nice guys, mike and joe.
   Knowledgeable and straight shooters, no push to buy, auditioned for me everything I asked.

 Had the adcom mono blocks hooked to the klipsch corner horns, that was bad, searing highs, bad!
 Switched to a pair of paradigm towers, and it was great!

 Choose wisely!

 Enjoy the hunt. 
 I would try them, do they have a trial, 30 days or something?
find out.
if u don’t like them, return.

I always wanted those adcom amps, but $ was my issue.      Ended up buying the onkyo m504, which i blew up,a few years later.

As far as I know, there is a dealer that has an ad on audiogon that offers a money back guarantee if you don’t like the amp.  I’m not going to give them a plug though, it’s easy enough to find the dealer.

At the end of the 80’s I remember drooling over Adcom adverts in the Stereo Review magazine, but I was a poor student and never saw them on the shelf until I bought my first in 2000.  I loved that amp...

BTW, if anyone is curious about the bigger 575SE, it has a total of 132,000 micro farads, which is pretty crazy.  Also, 24 matched output transistors and several other meaningful upgrades over my 565SE like a true balanced input stage and auto turn on options. 
At 350 wpc, you’ll want to have some serious speakers to do it justice.  Here’s a link if you want to get a better look.  Over 80 lbs.

As mentioned earlier, I've been running in the 565SE, and as of now have about 25 hours on it.  The new speakers have a little more, at 40 hours, so it's a little bit of an experiment trying to evaluate both at the same time.

The the way, if any are wondering about the validity of burning in new components, it certainly is a controversial topic and I don't mean to stir up anything, but I have found it beneficial in speakers.

As for amplifiers, my results have been more subtle.  I've read that capacitors need to break in.  In fact, they can view trace lines appear under the microscope of internal parts of caps.  I can't find a link of that right now, but with 4 18,000 micro farad caps in this amp, it can't hurt.

I have heard improvements so far as the soundstage has become more real, and the speakers have begun to disappear as it were.  Also vocals have become more transparent.

Anyway, maybe by next weekend I'll do some serious listening.

So I got a little frustrated with the Adcom amp, that I couldn't get it to heat up at all. The speakers are 4 to 8 ohms across the frequency range, with 4 drivers in a 3 way design.  They are on the efficient side at around a 92 rating.  I have to REALLY turn it up with these speakers to get the slightest warmth on the heat sinks.  So I became a little inventive.

I decided to try connecting my 4 ohm bookshelf Totem Rainmakers in parallel with the Energy CF-70's.  I believe the amp would see a load of about 3 ohms and under, depending on the Energy's.  I cranked it up fairly loudly, peaks of about 90 db at my seating area, but left the basement for the room above where the Adcom set up was situated.

It was pretty loud!  It become difficult to hear the TV unless it was cranked up somewhat.  I ran it like that for about a 1/2 hr, then went down and checked on the amp.  Well it definitely got warm, but only moderately so.  I could feel the warmth coming off the heat sinks, but I'd say that the heat management is pretty effective, and the amp has a lot of capacity in that department.  A 3 ohm load doesn't give it any trouble whatsoever.

I'm getting close to my 50 hour mark on the burn in, but I'm not fully confident whether that is enough.  The Oddyssey amplifier company suggests that components take several hundred hours to fully break in. They also suggest leaving the amp on while it goes through the process.
