adcom equipment.....

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. 

I'm continuing with this little Adcom journal for any Adcom fans that may look for Adcom impressions in this forum.  I know that I've done the "adcom" search here, and there is limited content to consider.

Also, I've made some after market improvements to my 565SE.  I've treated all of the fuses(5 of them) with Stabilant 22.  This is a substance that is a semi conductor until it comes into contact with electricity, then it becomes a super conductor.  It improves any electrical contact point.  4 Fuses inside the case, and the one accessed on the back.

Then, I'm not using the stock power cable, but a PS Audio AC5 cable instead.  It's a solid core, individually insulated copper conductor based design.  Every component in my set up has cables of similar design, and so are my speaker and interconnect cables.  

Speaking of speaker cables, mine(audioquest Rocket 44) are in a biwire configuration, so the little brass bars across the speaker terminals are not being used.

Each one of these items I've listed enhances or improves the end result.  YMMV.  BTW, I'm over the 50 hour mark, but am going to give it a little extra.
