seeking recommendations for a preamp How does one diagnose a standing wave ?@adrianleewelch If there is bass in other places in the room or the house but not at the listening chair then you have a standing wave causing cancellation at the listening chair. | |
Most Musical 6NS7 tube for a Preamp? @bdp24 Roger and I disagreed about his assessment of the 6SN7. For some reason he only used the early Tung-Sol documentation to support his views of the tube as you can see in the YT video. The issue was corrected by Tung Sol in later versions an... | |
built-in phono stages -- good idea? Wouldn't the shield box easily shield from the motor?It depends on the material. I've found over the years that ferro-magnetic materials in the chassis can affect the sound of the product. Especially when using a single-ended circuit though, placi... | |
Direct Drive vs. Idler Drive vs. Belt drive Right Atmasphere, if on a "proper stand" which includes the floor and everything under it, a situation most of us have no control over. On any wood joist floor you will be in trouble. Those of us on concrete slabs are lucky. I personally do not th... | |
HELP! - Need a Repair Recommendation for my Raysonic Amp It seems unlikely that the power transformer has failed- a rectifier is far more likely. .Power transformers have to be dipped in something very much like varnish to help them have low mechanical noise. Then they are baked- so you can get bubbles.... | |
Most Musical 6NS7 tube for a Preamp? The 6SN7 is in my opinion the best tube for a line section in a preamp. Back when we started using them the tube was considered obsolete and no-one used them at all. Obviously that’s changed in the last 30 years!The Pass Labs XA25 only has single-... | |
Is there such a thing as too much power? @alexberger +1 | |
built-in phono stages -- good idea? This would bring the following benefits to its performance:Elimination of the sensitive and susceptible phono cableReduction of the need for a balanced phono stage Reduction of noise without the need for balanced design -- half of the battle is wo... | |
Very basic subwoofer question In my bedroom system I don't have a lot of room and some recordings have bass that my tiny speakers simply don't even hint at.So I added a sub (Golden Ear Subx). I really had to fiddle with placement so I could hear the bass from my bed. A standin... | |
Need help replacing my beloved Magnepan.... Do you have a budget? | |
High Output Preamp for First Watt SIT-3? Do you believe the S.I.T.3 would improve SQ further if driving a 12 or 16 ohm speaker load (due to lower distortion) or is 8 ohms optimal for this particular amplifier?If the amplifier begins making a greater percentage of higher ordered harmoni... | |
Is there such a thing as too much power? You can never have too much power. Full stop.This statement is only true in theory. In the real world where we all live, there are practical considerations that cause this statement to be false.Apparently there is a need to explain why as I see a... | |
Recommended SET amp and speakers to 20k Getting hifi bandwidth out of an SET is challenging when the full power is over about 8 watts or so. Usually the bass is sacrificed so that the output transformer can make it to 20KHz. Often that works, since the speakers that have the sort of eff... | |
Time for the Dynaco to go, Affordable Integrated or Separates for Wilson's Under $2.5K? To refurbish the MkIIIs:Get the filter caps replaced. Replace the bias rectifier. Check the resistors- replace any out of spec. Check the tubes and replace as needed. if you want, get some good coupling caps- stay away from paper and oil caps as ... | |
High Output Preamp for First Watt SIT-3? @murphbass **All** amps make lower distortion into higher impedances. You can see this in their specs. You might think the difference to be 'negligible' but the distortion components involved are higher ordered harmonics. Since the ear uses these... |
