Hi, all! Today I've run into a problem with my GFA-535. When I went to switch back to it from a different amp, I noticed an unusual buzz start to come from my subwoofer when I turned it on. Not wanting to risk my Heresies in case something was wrong (glad it has speaker selectors!), I plugged one of my B-10s into the left channel on the other set of outputs. Once patched in, it revealed a loud, nasty static buzz (I also tested the other channel.) It only does it when it has something connected to either input. It could be a bare wire and it happens. I connected my iPhone as a source when trying to single out the amp from the preamp and it still did this, without seeming to react to the signal from the phone. It also seems to certainly cause feedback back through the inputs, as my subwoofer only buzzed when the amp and preamp were connected. Now, a few things that happened recently. First, one of the metal rings surrounding the right channel RCA plug had come out when unplugging it recently, leaving just bare plastic. I always assumed these were cosmetic, since the other one was never there (I received the amp that way) and it was never a problem. I also I believe I plugged the pre back in with the preamp still on (and the amp off). How could I go about diagnosing this, and does it seem like something I could fix myself? I like the 535, and while it would be fun to shop for a new amp, I wouldn't be happy to trash this one. Thanks!
So after completing a few extra jobs as well as off-loading some stuff, I find that I have a little extra cash to upgrade some components of my systems. I normally listen to my turntable but thought it time to get a proper CD player (as I'm just using a JVC DVD player that I picked up at a thrift store). Now, I want to add that I am usually pretty skeptical of CD player upgrades because I don't really know what I'm getting into. For me, the difference between a nice turntable with a great cartridge against a junk table has been night and day. I don't know if I've heard a CD player that has provided me the same difference. That being said, I'd like to lean on some of you here that probably have more experience in the CD player department. While I don't know much, I know that part of what you're paying for when you're buying a CD player is the DAC, and that some players are known to have much better DACs than others. This is where I could use some help because I know absolutely nothing about that stuff. BRASS TAX: So, I'd like to buy a used CD player below $300. That's not a lot, but I got other things in mind for the money too. Questions: What are some nice brands and models I should be looking into for that kind of money? I've heard Rotel and Adcom are good. I know Marantz to have made great vintage receivers, but that's about it. What should I be looking for? Am I hopeless if i don't have an external DAC? My current power sources are a Marantz 2230 and Sansui AU-717.
1) I'll be running my new-to-me Chorus IIs with an Adcom GFA-585.....250 stated watts at 8 ohms. Is that a good match....too much.... not enough??? Any comments/thoughts on the Klipsch-Adcom marriage in general???? I got the Adcom GFA-585 just a year ago and it seems pretty solid, thought I haven't had the top off and I don't think the original owner I got it from had any work done to it? I know I might need some work to the capacitors and there are some "upgrades" out there...... 2) I really wish I had some way of measuring the wattage output on my my Adcom system. Since 1987 I had my original Adcom GFA-545 amp, rated at 100 watts, paired up with my KG4s, also rated at 100 watts at 8 ohms, I always knew that when I started to see the clipping lights flicker that was all the volume I was going to get and I backed it off a little. Particularly since my KG4s are only 4 ohms (so the amp was pushing 200 watts with them). I've only had one of the tweeters on the KG4s kick off about 5 times in 27 years. Nice feature!! Anyway, I was a little surprised to discover that I could not find on ebay/online a good looking, quality "audio output meter." While we all know most McIntosh amps have them, my Adcom, and many others, do not. Anybody ever just arbitrarily add a set of meters to an amp?? I found some basic McIntosh looking meters on ebay/on line and thought of just adding them....somehow....... Any guidance welcomed!!
