| 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... | |
| glowing red output tube, but don't think it's red-plating @immatthewj 'Red Plating' is simply the tube dissipating too much power- too many Watts. It can be caused by a variety of things. Usually in an amp that was functioning the main reason is a loss of bias, which is to say a loss of control Voltage... | |
| glowing red output tube, but don't think it's red-plating During the incident, it didn’t look like red-plating to me; i.e. not red at the right angle crease in the plate, rather, the whole plate was red. @xenolith Pretty much the definition of red plating! First step: try replacing the tube. If the ... | |
| Phono Stage - The great analog tragedy Air capacitor advantage: the dielectric is not sensitive to polarity changes. Neither is mylar, polypropylene, polystyrene or Teflon. | |
| Don't try to fix these electrical prolbems with a conditioner! @erik_squires Totally FWIW Dept.: Most of the people I encounter who are interesting in a power conditioner have already done their homework getting the AC up to code with new materials and often a 20A dedicated line. They want to see how far the... | |
| XLR connection between Accuphase and Denafrips You're fine, all XLRs are wired the same, well I've never found one that wasn't. @lordmelton @nothelle Just so you know, in the US pin 2 of the XLR is non-inverting ('hot' is a terrible term to use as it implies the pin 3 connection, often call... | |
| Looking to Develop A Short List of Amplifier Candidates For A Pair Of JBL 4367 Speakers from the designer of the Purifi I believe, and his take on GanFet was quite interesting, in that the devices itself is not a game changer in terms of its relation to other output devices, but rather the circuit architecture matters more. @neonk... | |
| Impedance Loading for SS Hyperion @dover Actually what I am saying is that if you hear differences between 800 and 1000 Ohms it points to an RFI sensitivity problem in the phono preamp (its input, specifically). If that issue is fixed you won't hear those resistor differences any ... | |
| which turntable or how to convert to balanced phono setup? In gear that really does offer both a SE and a separate balanced input, the gain claimed by the manufacturer is usually quoted as being different for the two types of input, with the balanced circuit gain being higher. Why is that or is it a fal... |
