| 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... | |
| Watt do I do? Sounds like a great candidate for a tube amplifier. | |
| Looking for the best Preamp with a phono circuit built in That phono section is still great sounding as was the CD input. IME the phono section should sound better... | |
| Highest BUILD quality tube amps? ^^ They also build the equipment so it can be easily serviced. | |
| Rebuilding elgar 6000b conditioner? Replace the main filter caps. There are also some electrolytics on the circuit boards that should be replaced. Its also a good idea to remove the power transistors and reseat them with fresh heatsink compound. We've also found it to be a good ide... | |
| Upgrading path from Merlin VSM black magic That speaker has efficiency rated in the upper 80s- you do need some power. In practice it seems to be conservatively rated, but there is a reason why Bobby ran more powerful amps - 60 watts or more. | |
| Looking for the best Preamp with a phono circuit built in Maybe, but some AI preamps have three knobs. One is labeled as volume and the other two are labeled as left and right. How does that work?Pretty well.That's how our preamps are set up. The individual Gain Trim controls are used to set balance a... | |
| Recommendations on stuff to look at for upgrading a 300B SET amp Yes- I get what the allure of the SET is all about. That inner detail they are known for comes out of the fact that as power levels are reduced, the distortion decreases to unmeasurable. When the distortion is gone, detail is revealed. There aren'... | |
| The best coupling caps in power amp ?? Mundorf, Infinicap ?? We've not seen the bass restricted in any way with the V-Cap Cu caps. Its just very neutral. They are still the best caps we've heard- and one of the most reliable. | |
| Best LPs to Test Turntables One LP that brings many stereos to their collective knees very quickly is Paranoid by Black Sabbath. You'll need the original Vertigo English or German white label (not a promo) pressing in good condition. Most stereos simply can't play it at volu... |
