| Vinyl vs high def audio i.e. 24bit / 96 or 192khz From all the response so far, it seems like turntables are really for people who have a predisposition to love records, either because you guys already have a large collection, or because you could relate to it. While there might be some level ... | |
| Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other??? I'm also curious about how your development of a class D amp is progressing and whether it will utilize GaN or any other newer technology. @noble100Right now we're not using GaN transistors but they are certainly on the radar. So far we've ... | |
| Get your First Watt SIT-3 now? Actually, it seems like your speakers are among the highest efficient speakers and that most of the reviews or users reported no problems driving less efficient speakers. I don’t recall anyone having problems regarding the XA25 not adequately d... | |
| GaN-based Class D power amps Nope, it’s inherent in a lot of Class D. It doesn’t work quite the same way though. Some uses local feedback, which does not include the output, and some do. Feedback and a triangle wave oscillator is how the analog input is converted to PWM out... | |
| Who are some of elite sub woofers? The Audiokinesis Swarm is one of the best subwoofer systems out there. Most do things like 'bass in the room but not at the listening chair' due to standing waves in the room; the Swarm solves this problem (provides uniform bass at all frequencies... | |
| Get your First Watt SIT-3 now? V-FETs are finicky! The amp could be changed over but there would be more than just replacing the output transistors. Even the old V-FETs are hard to find. BTW the kit that was offered makes about 25 watts. IMO the V-FET was the solid state soluti... | |
| Tube Question for Audiophriends That's a pentode. Its a signal tube, not an output tube. | |
| Can we start a thread for folks who run a SET amp with a subwoofer or two? “a set of Classic Audio Loudspeakers model T-3s” And they are powered by? Amp specs please?I run them with an Atma-Sphere S-30 (a triode OTL with only one stage of gain) which can make about 45 watts into 16 ohms. The S-30 is full power to 2Hz so ... | |
| Small or big tubes/valves for pre amp ? This worries me a bit to hear, although I am no bass freak, I like tight bass, using a solid state power amp instead of tube power amp make any difference?'Tight bass' isn't natural bass, FWIW. It usually occurs in stereo systems where the woofe... | |
| Electrostatic pros and cons. I seem to recall that the Quads measured with the lowest distortion of any speaker available at the time (back in the 1960s-70s).The Sound Labs seem to be the Sate of the Art in ESLs. The newer ones are fairly efficient- once you translate the num... | |
| Looking for the best Preamp with a phono circuit built in I’ve gone back to SE RCA’ed designs, but my heart lingers for that balanced purest design. Single-ended circuits tend to feature the 2nd harmonic as their primary distortion component.Balanced circuits, because they cancel even-ordered harmonics,... | |
| Can we start a thread for folks who run a SET amp with a subwoofer or two? IMO, no tube amp or speaker can come close to pressurize a room with low bass the way a subwoofer is capable of. I have a set of Classic Audio Loudspeakers model T-3s. They employ two 15" woofers, one of which has a 22Hz free air resonance. They h... | |
| Recommendations on stuff to look at for upgrading a 300B SET amp Seriously, if you want to continue using SET amps, consider a more efficient speaker. You'll get a lot more mileage for your dollar. | |
| Tubes with Infinity IRS Betas We've had several customers with Betas. They used our more powerful amps- so despite the lower impedances they don't seem that crazy to drive. 200 watts seems to do the job. | |
| Finding the right tube preamp (input values) for Mccormack DNA You want a preamp with plenty of overhead, so at normal volumes it makes no distortion. That might be that 10Volt figure, although IMO that's a little low.Since you have NHTs the gain might be handy although most tube line sections won't have 28 d... |
