| Threshold, Levinson, Bryston, Krell, ?others? used amps As I am watching the MMA prelims, I am scanning the "A'gon pages. I might have missed something, but what speakers are being used by the op, how is the room set up, and can an improvement be made upstream, in the system, prior to the amp ? | |
| Speaker hiss from power amp Rwatson, a few more comments. BTW, welcome to the "Gon. As you stated, the hiss is not audible from your listening chair, so I would not worry about it. Putting your ear close to the power amplifier, it is quite common to hear the transformer. A r... | |
| Speaker hiss from power amp As a 2nd opinion, I concur with cleeds. | |
| How deadly is transformer hummm... I have an amp in my collection, a Smart Theater Systems TA 242, which is based on a Hafler design, nicely built power supply, toroid transformer, highly biased in class A, roughly 120 X 2. I acquired this years ago from a movie theater updating it... | |
| How deadly is transformer hummm... I believe I found a picture, that allows me to understand what atmasphere was speaking about. The power transformer, seems to be " sunken ", into the chassis, but imo, can still be isolated from the chassis, but likely, not with these that I recom... | |
| How deadly is transformer hummm... What you purchased, that I recommended, should be fine with temperature, as the mounting area, does not get as warm as other areas of the transformer. Additionally, heat rises. I would like to see a close up of the transformer mounting area, as I ... | |
| How deadly is transformer hummm... Wanted to add, I hear most transformers, when I place my ear, against the chassis of amplifiers ( including this Edge unit ), but, I accept this, as they all make noise, as I indicated. As long as it is not amplified, through the system, out to th... | |
| How deadly is transformer hummm... @atmasphere I have not been able to find a close up photo of the transformer mountings of this amp, however, I respect your opinion, and feel, it is quite unfortunate. As I have stated, I have done hundreds of these " mods ", and all for the bette... | |
| How deadly is transformer hummm... @listening99....check out Lowes...item # 198831, model # 88577......rubber flat washer...10 pack....I should have stated " washer ". Sorry. These work great. No need to tighten too much, as you want to keep the integrity of the rubber..... | |
| How deadly is transformer hummm... @listening99....I am recommending between the transformer ( where the 4 corners mount ) and the chassis ( the screws will go through the damping material / products ). Transformers do get warm ( in your case, the power transformer, not so much the... | |
| How deadly is transformer hummm... Humming is the obvious choice, when you do not know the words....lol.....Seriously......The truth of all transformers...... they all hum, radiate noise ( Toroids produce less than E-I core ) and exhibit, some amount of vibration, as well. I believ... | |
| Partly passive preamp? I use Tim Stinson’s Luminous Audio Axiom II, Walker Mod unit....3 in, 2 out, single ended, remote ( volume, mute ). Love it, as I can’t hear it. His cables are excellent, as well. Be well.....stay safe...... | |
| What isolation feet under your amp with great result? @mahgister....when you receive them ( Amazon ships quick ), experiment with the placement of them under the component ( s ) before you peel, for the adhesive. In fact, you do not need to use the adhesive.....Enjoy !, and my best to you, as well. | |
| The Battle between Stiffness And Damping Of The Speaker Enclosures! The descriptions state MDF is used for the cabinet enclosures. | |
| What isolation feet under your amp with great result? I have tried hockey pucks before, and the footers I recommended ( also from Amazon ) are, imo, superior......in place of the feet that come with the amplifiers, not in conjunction with them. BTW, for naysayers of isolation feet, isolation can happ... |
