| 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 ... | |
| Attention Horn Owners Aric Audio Custom 300b PSET and Aric Audio Super 6sn7 preamp. @earthbound Horns had better not be bright with that! In many rooms that amp would be a bit power shy on AN loudspeakers just so you know, based on the fact that any SET with zero f... | |
| EveAnna has sold her biz EveAnna was a straight shooter. I hope this doesn't mean she's out of the business entirely! | |
| Attention Horn Owners Reviews of some say they tend to be bright, which is a no go for my sensitive ears. Reviews did mention that Volti are not bright. So, any comments regarding ear fatigue and horn speakers or Volti speakers would be fantastic. @earthbound There... | |
| I changed a Tube and… @mfm22 Changing a tube in an amp or preamp is a classic way to change the sound and/or get it to sound better. The difference is not only audible, it can be quite measurable too. This is why there is such a market for NOS vintage tubes! | |
| Hattor Audio Autoformer Reference Preamplifier As to why, I never questioned it but assumed each autoformer has an input and an associated output tap depending on the voltage reduction (i.e., volume setting), and that one AVC was required for each audio signal line so, one per channel single-... | |
| Hattor Audio Autoformer Reference Preamplifier and offers four autoformers for the balanced version. @mitch2 Any transformer is capable of balanced operation. I'd be interested to know why they think they need four... | |
| use of ChatGPT for HIFI What are your experiences in using this groundbreaking tool? @emergingsoul It can be grossly inaccurate. For example it described our class D amps as zero feedback, which they are not; no idea where it got that from but it wasn't from our website... |
