| Best power amp for Quad 63 The advantage of an OTL on this speaker is due to the very high impedance the speaker has in the bass. This peak is not due to resonance. Solid state amps will throttle back their power into this impedance and so getting the speaker to play bass w... | |
| What's better, one conductor or two conductors for an RCA interconnect? @jumia @kijanki got it right in one. @deludedaudiophile , you are ignoring in your response that an RCA cable with a twisted pair and shield is in fact a coaxial connection. If the cable is very long this doesn't work so well, but in the shorter... | |
| S/N ratio Balanced input vs. Unbalanced input @auronthas The reason your amp is noisier with the balanced input is that the amp itself has a single-ended input; its not internally balanced. So the balanced input goes thru a separate circuit which adds noise. IMO/IME this is a sloppy way of d... | |
| Class D amplifier with TPA 3250 board Folks on another forum I shall not name seem to heavily imply that all amplifiers should sound the same (or very similar). They rave about these cheap tiny Topping/Aiyima amplifiers with class D TPA 3250 amplifier boards. These same boards are us... | |
| STAIN-LESS STEEL.......DYNACO CHASSIS'S......ST-70 and MK III @autospec Will, did you try Marksman? If I were you I'd be looking to Portland or Seattle for someone to made the chassis. That will keep your shipping cost down. You might get a local to do it too but I suspect they are mostly serving architec... | |
| Determining current flow to install "audiophile" fuses. @oddiofyl Don't do it- that sort of thing leads to fire. | |
| Looking for new/sealed blank high bias type II cassette tapes @chris_g https://www.atrtape.com/#cassette-tape To my knowledge the only cassette tape made in the US made by the premium US manufacturer of tape. | |
| Krell K-300i, RCA vs XLR The integrated is describes as having "fully differential circuitry that runs from the input stage through to the last output gain stage". That would suggest that an XLR connection is superior, but I would like to know if any real-world tests hav... | |
| STAIN-LESS STEEL.......DYNACO CHASSIS'S......ST-70 and MK III @autospec Will, we've done stainless chassis at Marksman in St. Michael, MN Of course you'll need a good drawing, preferably in some sort of computer file, like a DXF. But they can make parts from an actual drawing- don't send it on a napkin :)... | |
| Phono Preamp w/ Rumble Filter Current TT is a Denon 100th Anniversary with a 110 Anniversary MC cart, but may eventually upgrade them as well. If your phono is set up correctly you should not have problems with rumble. My speakers are flat to 20Hz and my preamp (including ... | |
| Input, please The silver dress panel isn't bolted in place?? | |
| Competitive class D amp suggestions One thing I’m still not clear about is why people describe class a and high bias a/b as being warm sounding especially if their overall distortion is on the higher side? The distortion can be quite low! The tricky bit is knowing what is meant b... | |
| Congratulations Atmasphere! Just reading this revived thread. Makes me miss AL.... @atmasphere Ralph, you guys were a good team of sorts. Al always had your back and really had my back too. Miss my friend. Al was both a gentleman and a scholar. Also a good engin... | |
| Competitive class D amp suggestions I still am not sure about some basic things. Now i suspect that the "higher order harmonics" are not second and third order harmonics but 4th, 5th etc order harmonics (just to clarify, in my earlier posts i referred to "higher order harmonics" a... | |
| What are we objectivists missing? Well, this did not go in the direction I had intended, but I suppose I should not be surprised. I guess the take away for me is "We don’t know what we don’t know". @jtucker There is a simple way out of this. Usually the problem is sorting out... |
