| The smoothest amp you've heard? many tube amps are closed in on top, not airy. so they may be butter smooth, but it’s a circuit artifact overlayed over all the music, and not ’the’ music. @mikelavigne The quality of smoothness is a lack of higher ordered harmonics; also a lack... | |
| Firing up old tube amps. Should I worry? Best advice is to inspect them for bulges or leaks, then use a variac to raise the voltage slowly and give the capacitors time to re-form.They won't have bulges if they've been sitting.The traditional means for reforming/testing the filter caps i... | |
| Are Pre-Amps necessary? but look how much longer that has taken than anyone thought.About 40 years so far and still counting... And now tape is back after a long hiatus. And we're already to the point where the industry doesn't want to make CDs anymore. For digital, stre... | |
| Subwoofers going into standby with low volume listening (New Integrated Amplifier). But dually concerning is that even when I crank up the volume on the subwoofer, they sound extremely tame and subdued.It sounds like the volume controls on the subs are set too low. This will help them sound less subdued and also stay on more.BTW ... | |
| Tonearm adjustments on the fly In my opinion TriPlanar is ugly industrial design while the Reed 3p is pretty elegant (remind me of DaVinci tonearm a bit). It is, but also features the hardest metal bearings used in any tonearm made worldwide. This allows the bearings to be adju... | |
| A little tube magic? Does the product have a name or number? When will it have a page on your website with pics? What is the gain and input impedance? No. Soon. About 28dB and 100K. | |
| Are Pre-Amps necessary? They are not needed these days with nearly all of todays sources, except maybe with weak tube output sources. Sheesh. It was nice when george was off. Now we have rehash this again and again. Tape is still very much with high end audio as is the L... | |
| I'm a Dummy, Tell Me About Turntable Mats as I understand it, you put them on with adhesive.Some do, some don't. One of my favorites, the pad made by Oracle, uses an adhesive. The function of the mat is to control resonance generated in the vinyl by the act of the cartridge tracking. If y... | |
| Are Pre-Amps necessary? Not when many poweramps use opamps as their balanced inputs, and then it routes to their single ended input. In these cases by using the single ended input, you get a better sound, as there’s no opamp in the signal path then.OK George, by this co... | |
| How important is the pre-amp? This is false.To explain to members with the maths of it.As a 10kohm passive has an outuput impedance of around 2.5kohm, the "cheapest interconnect cables" can be <100pf capacitace per ft and less. It would if be use you 2mts!! of it, still be ... | |
| Execution matters So many companies start with good intentions. Hire great electrical engineers with audio experience. Then it's handed over to the mechanic and design group. Then the marketing and finance group gets involved. Then it's handed off to a contract man... | |
| Analyzing Balanced versus Unbalanced Amplifiers--Difference in sonic quality? I wanted to see what the new Technics high-end products touting new technology were all about. What Technics did here was create an LAPC circuit that tests and monitors speaker output via a computer chip versus balanced sound. According to Audi... | |
| A little tube magic? Ralph,Are you shipping your GaN amp?.....if so, what do the customers think?.....and how much is it? Any specs besides 100 watts?@ricevs We are shipping limited production. We posted one customer's comments (which seem pretty typical) on the feed... | |
| Recommendation for a highly resolving amp have you tried different tubes for the sachs preamp? most 6SN7s can be overly smooth. This statement is false. Design can have an enormous effect, but 6SN7s of themselves are quite linear. I have Don Sachs 2 tube preamp driving Pass Labs X350.5 ... | |
| How important is the pre-amp? @unsound You really do have to wonder what the designers of Redbook were thinking. In all cases of a Redbook output driving an amplifier, the voltage has to be knocked down, often quite a bit.Many amps are 1.5v or less input sensitivty for full o... |
