My system is getting worse - now what?


Hi all,

First post and I need some guidance. My system started out in the mid-80s with a Hafler DH-500 amp, Adcom GFP-1A preamp and ADS 810-2 speakers. I was perfectly happy with this system for 15+ years except for the occasional cut-out of the Hafler during high-volume sessions, which it did for protection. Eventually the Adcom had a channel signal drop happen enough I had to retire it. I replaced it with a Paradigm as it was one of the few affordable preamps with a phono section. I am nowhere as pleased with it musically as with the Adcom. Recently I grew increasingly frustrated with the Hafler cutouts at volume as well is its general fan noise during low volume operation and sold it. I replaced it with an Adcom GFA-555 based on friends having them and reviews, but I am not happu with it. My ADS speakers hate it at volume, resulting in woofer distortion and it just sounds far less musical. So now I am in a quandary. I can tell the Adcom is more of volume amp and I think I can live with it after I get my ADC equalizer set, but I don't think the ADS speakers will ever take what it gets handed. So I think I want an affordable floor standing speaker that will take whatever I can throw at it. I will even consider getting another GFA-555 and bridge to mono if that will help. So ... is there any affordable ($1000-1500) speaker that will sound as acoustically beautiful as my ADS's and be allowed to be driven to extremely loud volumes when the occasion arises?

ADS L810's are a classic. The soft dome midrange made them popular. I believe Telarc used ADS in their studio before they switched to ATC - although I don't recall the model. An option might be an old pair of JBL 4435's but if you get them for around $1000 you might expect to have to do some work on them (bumoed up and reconing needed). They have mylar caps in the x-over which also need changing to polypropelene or other suitable higher quality cap. They would certainly rock out and could take everything you throw at them. A newer option might be a used pair of ATC SCM 40 - these also play loud despite they are a small speaker.
Stonedeaf,

Your advice is right on. The whispy sound is sometimes sounding as if air was leaking out of the speaker. Another trick I use is to touch the woofer rubber surround very lightly while playing music softly - normally the sound does not change - if it does then VC rubbing may be a problem. Another check is to lightly "tap" the edge of the cone (about an inch inside the surround rubber) with a finger and listen to the sound as you go round the cone...if the sound changes at some point around the circumference then it may indicate a rubbing coil.

I would add that DIY re-coning is not hard to do IF you can find the correct replacement parts (this may be a problem for ADS who is now defunct). See this for a discussion on ADS drivers
