New Member Needs Help


Hello everyone.  I am a new member and could really use some advice.  First, I hope I am posting this in the right section since I suspect the problem lies in the area of my electronics, although admittedly I am not sure.  I was a budding audiophile in my younger days and accrued some equipment, all bought new.  It consists of an Adcom GFA-555 amp, Adcom GTP-500 preamp/tuner, Adcom GCD-700 CD player and a B&O Beogram 1700 turntable.  I am using a set of Soundwave Grand Soliloquy speakers.   My wife would sometimes turn on the equipment for background music but there really hasn't been any serious listening in years.  

Having just retired I now have some free time, so after checking all the connections, I began listening to the system using the CD player as the source.  Overall, I thought it sounded very disappointing - pretty harsh and a bit thin, lacking in bass.  I couldn't listen to it very long.  I then tried the turntable.  The sound wasn't much different but the belt on the TT must be shot and the resulting rumble made serious listening difficult.

Having done some searching on this forum, I decided to pull the speaker cloth and examine the Grand Soliloquy speakers.  They looked perfect.  The cones and surrounds were butyl? rubber and looked good, as did the glue, which I read was a weak spot on some early model Soliloquys.  

So now I am wondering where to go next.  Could the amp/preamp have deteriorated that much with time?   Is that something I would audibly notice?  Would the crossovers in the speakers deteriorate over time?  Or maybe it is just my memory and I don't remember the sound very accurately?  And is any of this equipment up to today's standards and worth saving?  

I also have a pair of Ohm Walsh 2 speakers and an old Harmon Kardon HK730 receiver packed away that I could haul out for a comparison, but I am not sure that will answer any questions, and might confuse me more.  I appreciate any and all ideas from forum members.  Oh, and my room is large - about 14X22 feet.  Sorry for rambling a bit but thanks very much in advance.

Hi JPL,

The equipment that you have is 25 or so years old.  When I broke up with my wife in 1990, one of the first things that I did after I rented an apartment, was to purchase for myself a nearly identical system ... Adcom GTP 500 II preamp/ tuner, Adcom 545 amp, Magnavox 630 CD player, and KEF Q55 speakers.   

If I read your post correctly, the system has always been connected, it is just that you and your wife did not do a lot of listening over the years.

What Tom has suggested makes sense ... let your system run for several days and then listen closely to see if you feel the same way.  If you have a real audio store nearby (Best Buy does not count) go listen to new speakers with music you are familiar with.  Speaker standards have changed pretty dramatically over the last 25 years.  So has your memory, if it is anything like mine.  

Adcom equipment was the first step up to the big leagues for a lot of people when they upgraded from the popular receiver/ turntable/ speaker set-ups in the 70's.  Adcom made serious looking black boxes.  In your current set-up, the weak link is the Adcom preamp/ tuner.  

Adcom preamps were never smooth ... but they were not so harsh sounding that listening was intolerable.  Even though Adcom represented a true step-up at the time for myself, the system was never consistently pleasing.  I stayed with the Adcom components as the system anchors for about a dozen years.  I changed out the speakers and cd player along the way, which helped.  It was when I swapped in an old Marantz 2230 receiver for the preamp, that I noticed how lacking and limiting the Adcom preamp was.  

If after a few days you feelings about your set-up have not changed, I might be tempted to swap in your HK 730 receiver and try it as a preamp or have it go directly into your speakers and see how it sounds.  One point to note is that that your HK is even older than the Adcom and may have issues of its own.

You have some homework.  Let us know how you make out and we can take it from there.  Fortunately, there are a number of real alternatives out there that are reasonable cost wise to pursue.

Nelson Pass did design the original 555.  You may want to read through this thread ... url=http://www.diyaudio.com/forums/solid-state/5280-adcom-555ii-nelson-pass.html.  

With that said, I would be asking the question ... does it make sense to rehab 25 year old equipment?  Did you like the Adcom equipment that much back in the day?  These can be tough questions.  Do you want to make major purchases having just retired.  I know as I ponder this myself ... I will be 59 and most of my equipment is at least a dozen years old.  I sometimes am tempted to sell what I have, buy all new Mcintosh  equipment, and let someone else worry about disposing it all in 20 years or so.  Such nice thoughts for a Sunday.    

None of this negates my feelings about the preamp being the weak link.  I don't know your speakers.  My inclination would be to start new with the major pieces, buy the best that I can afford, and be done with it.  I have been burned with enough vintage and older equipment over the years that I am inclined to buy quality and to buy new.

So here comes the big question ... what is your budget for replacing the preamp/ amp/ and player?  If you are considering new, I believe that you are looking at 3 to 4k for an integrated and CD player from companies like Creek or Rega.  If you like receivers, there is the Outlaw RR2150, which I have been using for 10 years, which would leave you plenty of dollars for a CD player and new cartridge.
