Presently using Adcom's GTP-760 and GFA-7000 amp...have not been very happy with the system...had to have the amp repaired early on and I am "living" with a DVD dig audio coax input that does not work (use dig 2 for the DVD). Have I had bad luck?
Any input on Adcom out there? Considering 950/770 as a replacement system and step up to 7.1

I don't have any experience with Adcom, so I'm somewhat hesitant to answer, but I will say that I was somewhat surprised last year when I was putting together the first version of my pre/pro chart that the Adcom GTP-830 had a pretty low rating at AudioReview -- 3.0 on a 5-point scale with five reviews.

You'll find plenty of people here who are very happy with the 950/770 combo. It's definitely a good product and a good value.

i bought an adcom gtp 600 in the pro-logic days.

it's the single, worse sounding consumer electronics piece i ever bought.

i've read some articles (scanned is more like it) that say adcom is making improvement, but you'll not likely ever convince me. once bitten, twice shy.

I had an Adcom analog preamp/tuner plus power amp a long time ago. I liked them, but I honestly felt that they didn't match up well against other "value oriented audiophile" gear. Acurus, Parasound, Sony ES, Rotel, etc.

Back in the day when I was using an external DD decoder (Onkyo ED-901) with a "5.1 Ready" receiver (Onkyo 919 - fantastic piece!) I got an Adcom DD decoder attempting to "upgrade" my DD audio quality. The difference between Adcom decoder and my Onkyo was negligible and I ended up selling the Adcom away. It sure looked cool though!

I believe the quality of Adcom has declined over the years.
I, myself bought two Adcom GFA-555 Amplifiers back in the mid eighties, and have no problem with them, other than having to replace their power switches (both of them). They have state-of-the-art great sound. They served me for great quadriphonic sound untill I got the 950.I bought one more used about two years ago, and they are the heart of my system (along with the 950). I also had one of their two channel pre amps (GFP-565), which the 950 replaced. Can't speak for their processors. Heard they didn't sound too well. I know I considered their processord too, but soon forgot them, as they weren't up-to-date with features (such as multichannel inputs and EX/ES).
I understand they are finally coming out with a new up-to-date [finally] processor.

I have the GFA7500 (150w x 5 THX cert amp) and it sounds great with my 950. I have not heard the pre/pros, but I have always liked the sound of the adcom amps. The new ones are even more powerful (and expensive)...if I had to go back (and not get a dealer deal on my adcom) I would definately go with the 770 or 755!

appreciate the thoughts on Adcom....in the process of re-setting up after a move (NJ to TX). Best set-up due to space restrictions does not allow rear access to equipment (can not convince my wife that no one will notice the hole in the kitchen wall).....that leaves me with a massive wire management problem....5 wires from amp to pre/pro plus 5 speaker wires, 6 wires from pre/pro to DVD (SACD), component out DVD, component out HDTV, S-video (4) out NSTC, LD, VCR, out from pre/pro to projector. Audio (1) optical out from DVD, coax out from HDTV, left/right out from reg tv, LD, VCR. 7 power plugs.....at least 34 wires (what did I forget)...no matter how I try it looks like hell....I will not go into the dumb mistakes I have made so far. Despite my lack of finesse I love the challenge.

I agree with surroundophile. I owned a GFP-565 preamp and a pair of GFA-565 monoblocks for about 14 years. During that time I auditioned newer stereo-only components from Adcom and other makers such as Rotel, NAD, etc. At their price-point I found nothing to compare. I use an Adcom GTP-502 preamp/tuner and GFA 5002 amp in my office and it works just fine for me.

I personally like their older amps (535, 545, 555, 565 and 585) better than their newer amps with the exception of the 5002 and 5006. Their HT pre/pro's have been plagued with many problems and have not received very good reviews in either magazines or more importantly from users. IMO.

Well I still have an Adcom 555 used in bridge mode i believe is 600 watts at 8 ohms and I use it for my new JBL-Pro Cinema Subwoofer,it is perfect for my needs, no problems in the last 15 years,also I had some 565 mono blocks that I gave away to my brother when I purchased the subwoofer(a real Sub)I find no need to have a lot of power for my mains since they are very efficient.Anyway no problems at all with the Adcom amps.

My feeling and most of the respondents agree that the older monoblocks or 2 channel amps by Adcom are seemingly indestructable. It is the 5 channel THX HT amp that was my problem be it the least of my problems....it operates perfectly now. It's the GTP-760 pre/pro that makes me regret my choice of Adcom .

I use 3 Adcom amps in my system. A GFA-5800(250 x 2) powers my main speakers. A GFA-5503(200 x 3) powers my center and rear speakers. A GFA-5400(125 x2) powers my 6/7.1 speakers. I have been very happy with this configuration. Lots of SLAM with very dynamic sountracks. The GFA-5800 also is a very good sounding stereo amp. I replaced a Sony TA-e9000es ver. 2.01 with a Outlaw 950 to be able to play sacd and dvd-audio discs and to have the analog pass through. I love the 950, but the sound on my system is a notch more forward when compared with the Sony. This is not a bad thing to me, but just an example how changing any link in the chain can affect overall sound quality and how the amps are just playing whats being fed to them.
