| Newbie Can't Decide Which Tube Amp @ckenrIf If you really want to use a tube amplifier I would consider different speakers unless your room is very small. 87dB is low efficiency and you'll need about 240-400 watts in most rooms to get realistic levels with any musical genre. Ther... | |
| Class D Cyrill Hammer is a good designer but entirely mistaken in his comment you quoted. When class D amps (Purify) are making distortion that is 120dB down, it is serious cutting edge; lower distortion than the Soulution amps. Again, you need extraordin... | |
| Class D Yes like the ones and their lackies pushing yet to be released commercial products, with fanciful claims that will only be proved right or wrong "if" given access to by independent measurement testers.To be clear here, the 'fanciful claims' were... | |
| Hiss from speakers that increases as loudness control is decreased The preamp needs service. The first thing if servicing this that I would check would be the power supplies- making sure the filter caps are fresh, and that the regulator isn't oscillating. If that did not sort it out I would be looking at the circ... | |
| Class D Every one knows "global feedback" is not a good thing in any amp, it’s a "sound sterilizer" and should only be used very sparingly if possible, just to clean things up a little, and preferably use only "local feedback". Which won’t help your pl... | |
| Speaker sensitivity vs SQ @phusis The T-1 has a 250Hz horn, using a 4" compression driver that is field coil powered. The diaphragm is made of beryllium and employs a Kapton surround, which is how it goes so low without breakups. I don't know the spec on the T-1 but I do k... | |
| Speaker sensitivity vs SQ Some of the older Horn loaded speakers like Altecs and JBLs that I had a lot of experience with when I was young were all very colored. Back then K horns were the best but they did not image well and though not as colored as the other horn spea... | |
| Speaker sensitivity vs SQ @mijostyn I don't know about Curl's designs so much, but Nelson does make fully differential amplifiers so he is able to take advantage of the lower distortion afforded, and yet have a nice 3rd to help mask the higher orders. | |
| Speaker sensitivity vs SQ What are the T3’s sold for - close to $100k? Re: mentioned "better interface" it reminds of what Simon Mears told me of the importance of the coupling between the compression driver exit and the throat of the horn it’s mounted to; transition, tran... | |
| Class D The 1200AS 2 is still the current Class-D module from ICEPower, what have you been sniffing.https://ibb.co/vvwzGV5https://icepower.dk/products/amplifier-power-modules/as-series/ Nothing but air. However if you are suggesting that this amplifier is... | |
| Class D Once again, straight into product protection modeThis statement is false. I've simply been engaged in correction of misinformation. That is why I used the phrase fake news. But I could use others- ignorance comes to mind. Misleading. Deceptive. An... | |
| How to Eliminate Hum? CDP + Pass Preamp + Amp Setup. @88man The preamp is having a problem. If you can send it back I would do so. If your integrated amp is alright, its pretty safe to assume that there are no problems with the AC line. | |
| Speaker sensitivity vs SQ How would you compare them to the likes of JBL Everest’s (DD67000, or one of the other two variants), if you heard them?I have. The Classic Audio Loudspeakers are **easily** in the same league. If I had to compare, the CAL is a bit smoother, owing... | |
| Acoustat Electrostatic spearkers @bdp24 That does not sound like it would be all that hard to come up with something. People have done that successfully for the Sound Lab. | |
| Vfet / SIT Amplifiers @zm Me too. You might take some of my comments that were previously misdirected, and scrutinize your preamp. It should not be a volume thing that make an amp 'wake up', unless it has a malfunction (which, to do that, would probably be bias-related... |
