Bubo Posted May 5, 2015 Share Posted May 5, 2015 I had the gains turned way up on my amp which was causing the hum to be more noticeable....now that Ive turned them down its not as noticeable. Its still not "black noise" Hum is typically a grounding problem, at least on solid state it is. Quote Link to comment Share on other sites More sharing options...
Bubo Posted May 5, 2015 Share Posted May 5, 2015 You can pick up an excellent condition used totl surround receiver, preferably THX certified, for whatever you feel like paying off of Craigslist. Read the reviews on the units that catch your eye and check for comments on the forums, just search on Google with the model info AVS will probably pop. Pioneer Elite, Yamaha and the TOTL Sonys come to mind. This gets you a class AB integrated with all of the decoders and interfaces for a couple of hundred dollars, you can set them up to run as stereos.....2.0, 2.1, 2.2. My Mac, Yamaha MX amps and Pioneer Elite AVRs are all dead quite on full volume with no music. Quote Link to comment Share on other sites More sharing options...
russ69 Posted May 6, 2015 Share Posted May 6, 2015 I didn't read all the posts. Do we know the other components in the OP's system? Is he looking for sweetness or ground pounding? Sorry if I missed the facts but I can't recommend unless I know about his system and requirements. Quote Link to comment Share on other sites More sharing options...
Mallette Posted May 6, 2015 Share Posted May 6, 2015 See, Russ? WHICH COAST! Anyway, I have several SA-XRs in service and think they are pretty extraordinary. I buy them because they are cheap and sound like a million bucks. And dead quiet. If you have a good pre, the Crown Class Ds are pretty incredible for the money. Those at the Hope gathering...including the guy at 1.6 miles away...can attest to that. Dave Quote Link to comment Share on other sites More sharing options...
Guest Steven1963 Posted May 6, 2015 Share Posted May 6, 2015 (edited) I'm having this problem with the Dynaco tube amp I picked up with the Heresy III's. VERY noisy with the Khorns. And if I add anything into the signal path it gets even worse! Didn't have this much problem with my DBX amp but it had to go into the shop and I won't have it back for another 4 weeks or so. I have to live with it until then. After that I am thinking I will sell the Dynaco. Tubes just don't appeal to me. But glad I tried them. Hi - Steven , what was the model of the DBX amplifier you have on repair -as far as the tube amplifier being noisy , can you elaborate more -thanks - It's a DBX BX3 Mii. The noise in the amp isn't a hum, it's a buzz. And I mean a seriously loud buzz. I haven't broken out the meter yet, but at a guess I'd say it adds 10db at idle, conservatively. Just annoying as all hell. I've tried everything I can think of: swapping cables, eliminating the preamp and going straight from source (google play using my phone for volume), keeping power/speaker cables apart. I even had the amp apart last night looking for loose connections and I removed all the tubes and reinserted. Nothing helps. It's got to be a bad part somewhere but I'm not a tech so I have no idea where to start. I can't put it in the shop right now otherwise I'd be completely without tunes until the DBX comes back which isn't for another 3 weeks or so.

Guest Steven1963 Posted May 6, 2015 Share Posted May 6, 2015 Steve, don't let a bad, unrestored Dynaco tube amp forever remove consideration for tubes. I have had incredible tube amps, and I have had lousy tube amps. They are not all equal. The Dynaco ST70 tube amplifier was a new built up kit -not an original Dynaco st70 amplifier - Yeah, Triode Electronics kit. Quote Link to comment Share on other sites More sharing options...
khornbred Posted May 11, 2015 Share Posted May 11, 2015 yet another vote here for the panny saxr series receivers. ignore anything you hear from any other sources than Klipsch users about them, results are mixed with lower efficiency speakers, the panasonics really shine with most any klipsch. 1 Quote Link to comment Share on other sites More sharing options...
CaptnBob Posted May 13, 2015 Share Posted May 13, 2015 I don't know how strong your antipathy towards firebottles is, but Quicksilver used to make a moderately priced tube amp for efficient speakers, called, appropriately enough, the "Horn Mono." Cute little things, and really quiet. Stay away from the solid state H-K Citations. Good sounding, but, even when they were new had a reputation for being a bit noisy. I know mine were. The Dynaco thing might be a tube giving up the ghost. Quote Link to comment Share on other sites More sharing options...

Gorm Posted May 19, 2015 Share Posted May 19, 2015 looks sweet but I gotta pass..... I also have my restored Fisher 500c for sale. But its integrated, and it looks like you might try to be getting out of tubes. Its dead quiet on my Cornscalas. The unit itself does have a tiny amount of hum if you put your ear like right ontop of it. Quote Link to comment Share on other sites More sharing options...
Jonathan Wood Posted May 19, 2015 Share Posted May 19, 2015 (edited) The quietest and best sounding amp I've used so far with my KPT-904's is a Red Wine Audio Signature 16. It uses a battery and a smart charger to compleatly isolate it from mains power. Dead effing quiet. And a single tube buffer stage to add some sweetness. It's amazing. I got mine used off AGon for about $1100. - Woody Edited May 19, 2015 by Jonathan Wood 1 Quote Link to comment Share on other sites More sharing options...
Eddie 500 Posted May 29, 2015 Author Share Posted May 29, 2015 I pulled my old kenwood kr 5600 out of the basement for a compare. Soooo much quieter than the behringer a500........ I don't think it was a ground issue just not sure why the behringer made that annoying hum. Happy again Quote Link to comment Share on other sites More sharing options...

deadlift Posted June 2, 2015 Share Posted June 2, 2015 Give Quicksilver Horn Mono-Blocks a thought I use them with my La-Scala's and there is dead silence nothing even with your ear pressed up right to the speaker and they make beautiful music together.

Ski Bum Posted June 2, 2015 Share Posted June 2, 2015 The Quicksilver Horn amps are purposefully low gain. So is that new fancy Benchmark amp for that matter. Those eye popping, DAC like specs don't just result from fancy circuitry (although their achievements are nothing to scoff at), as simply having lower gain helps those numbers considerably. Whether you go with tubes or a state of the art amp like the Benchmark, sensible gain staging of the system is a key ingredient in the "dead quiet" recipe.

Eddie 500 Posted June 3, 2015 Author Share Posted June 3, 2015 Seems like one of the monster Pioneer SX-series integrated amps may be the way to go for me. Now to find a nice one. Anyone wanna sell me theirs???? Quote Link to comment Share on other sites More sharing options...
