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.

I have tried Adcom and was quite disappointed. Nelson Pass is a great designer, so it might be the preamp. A similar company, Rotel made preamp/tuner combos, and the ones I tried were terrible, much worse than the Adcom I had for a while. It even sounds muddy as just a volume control for my subs. A Preamp/tuner seems to sacrifice a lot. I would start here. 

Also, CD players have improved the most over the last 25 years. My old Denon 1500, a "Stereophile" recommended one 25 years ago, really does not cut it anymore.

A really good budget one is the Onkyo DX-7555, for around $200-300 used. The remote has to be used to set the tweeter something or the other, and it makes a noticeable difference. I would also suggest a good phono cartridge upgrade. 

Your term, "Lacking in bass" is relative. Music has a lot more bass now than it used too.

I assume you listen in your car. Compare that system to one 25 years ago and consider that the inadequacies of your home system  are more obvious because of the comparison. I used to love my stacked Advents, but they sound pretty bland now. They have not changed. Everything else has.

If after cleaning all contacts and running your system in you are not satisfied, you might purchase a used integrated amplifier, one that is not too old. Even should you upgrade beyond, it could be sold without much loss. Regarding the TT, a new cartridge is probably required.

I've had some build quality/reliability issues with Advent. Take a look at NAD and Parasound

Golftime, I envy your golf time! congrats on your retirement! 

I had an Adcom 555/555 set for a while in one of my setups. Adcom was good value for money in the 90s, but I was shocked when an unassuming little Naim Nait 5i integrated amp that I had bought used simply made music more enjoyable.

If you gave me your rig, I'd ditch the Adcom front end, right down to the CD player. I'd want to see what those speakers and a little tuning to your Beolab can do with better electronics in the chain before condemning those.

I really like mesch's suggestion to borrow a nice integrated to try in your setup. If you are in Virginia, let me know. I'd be willing to bring a couple of mine over for you to try. I don't have anything high end, but everything I have I preferred to the Adcoms in any speaker matchup I've tried.

Another option is to try something like MusicDirect online that has a 60-day return policy. Contact them first to see what exactly it entails, but it is an option. If I were in your shoes, I would contact them to try a Rega Elex-R to see how that works in your system, better or worse. It may at least be a way to shortcut yourself to some answers about your turntable and speakers. If it works a treat, you know you are on the right path. Another option is something like a Naim Uniti or other all-in-one type product which may not be your cup of tea, but that may let you assess what replacing your entire front end electronics in one go would do for you without getting into mixing and matching a bunch of differing components.
