| Distortion Distortion Distortion @bjcatanzaro Distortion, for the most part, is the differences you hear between components. For example the smoother tonality often attributed to tube equipment is due to harmonic distortion. Our ears use higher ordered harmonics to sense sound p... | |
| Fritz carbon 7SE MK 2, Upgrade @robshaw We showed with the Fritz Carbon 7s last year at AXPONA. I found them quite transparent and neutral. We ran them with a sub crossed at about 55Hz. I run Carbon 6s in my bedroom system, using an amp of only 5 Watts/channel. It will be a har... | |
| Just got a new power amp @kijanki Right. (We introduced a class D amp of our own design about 4 years ago FWIW.) The question then becomes, in the context of this thread 'is it important?' WRT the thread title, it isn't. Ampex made a tape machine that was used for quite... | |
| Just got a new power amp One criteria of balanced output is lack of GND return current. @kijanki So if one side is at ground, but there is no ground return current to any other part of the amp, your criteria is satisfied? Or is the fact that the speaker circuit is not ... | |
| Just got a new power amp @kijanki Did you not mean to use 'S300' twice in the above post? | |
| Just got a new power amp @kijanki It looks like that amp is. But: I would not use a speaker terminal at ground as your definition, although our OTLs have both speaker terminals ungrounded and floating. Many ARC amplifiers do not have a grounded 'common' terminal; th... | |
| Phono Stage - The great analog tragedy @pani Just for the record (if you see what I did there) I was not making that claim. Just my means of reference, so as to avoid the 'fantasy' (as you put it) of live vs recorded. | |
| Class of operation for Tube Power Amps @westcoastaudiophile my comment was related to “real” class A design, not hybrid (pseudo ab) A2/A3 with enabling output tubes grid currents! Class A is defined simply as the output device does not go into cutoff at any point of the waveform,... | |
| Phono Stage - The great analog tragedy for once I don’t feel the need for a live music uncompressed recording to tell which equipment sounds more correct. all this comparison with live music is ultimately a fantasy. @pani I don't see these two statements squaring with each other.... | |
| Just got a new power amp @kijanki Its hard to know what Emotiva is talking about since there appears to be a typo or complete misunderstanding of what is happening in the opening sentence of the quote of the description; power amps do not drive the input, if you see what ... | |
| Phono Stage - The great analog tragedy all this comparison with live music is ultimately a fantasy. We all know live is so far in a different realm than reproduced music. Forget live, even a direct from microphone is so much more laden with information and dynamics that most “recordin... | |
| Just got a new power amp @kijanki Our OTL tube amps are fully balanced and differential. But to the best of my knowledge, there's only one output section (which is push-pull) driving the speakers. Does this meet your definition? | |
| Class of operation for Tube Power Amps just plug amp into ac power (or current) measuring unit, and dial the volume control.. class A power consumption is not sensitive to volume, while AB will consume significantly more with volume increase. @westcoastaudiophile This is only true ... | |
| Bi-amping question - XLR out split That’s a fair point but it’s actually the other way around - you’ll get the higher input impedance on the balanced (XLR) inputs. @cleeds Unless you don't. For example the input impedance, balanced or single-ended, of our class D amplifier is ex... | |
| Just got a new power amp If there is an audible difference, something is defective. @kr4 I'd put it the other way 'round. We audiophiles are very used to hearing interconnect cable differences. But recording engineers, who use balanced lines in a studio, are not. When ... |
