| Does Anyone Know the History of the Early Sota Turntables? If all aluminum I think there was a Supermat that was used to damp it. @neonknight The Gen 1 Sapphire did not use the 'Supermat' as I told you earlier. Here is more information: The Supermat was designed by Warren Gehl of Audio Research (altho... | |
| What exactly is PRaT??? @soix If its fast, it must not be bright. If its detailed, again that should not be in tandem with brightness. IOW you're making progress when its both smooth and detailed at the same time. The goal of the system is the music, such that you don't... | |
| What exactly is PRaT??? @soix To understand PRat, you have to understand that the ear/brain system has tipping points. If the system is too distorted, if its too slow, stuff like that, the music processing (which normally occurs in the limbic portion of the brain) is tra... | |
| Would like to try a tube preamp after years of solid state and hybrid @charliehorse If you are looking at an older tube preamp, keep in mind that its power supply might have to be serviced out to be reliable. Some of the preamps mentioned on this thread are so old that by now the filter capacitors in their power s... | |
| Spatial Audio Raven Preamp Personally, I find the tonality and subjective realism of transformer-coupled vacuum tubes to be unmatched by other technologies, but that’s just me. There are class D amps now that easily rival the best tube amps for every quality mentioned in... | |
| The Shure V15 V with a Jico SAS/B stylus VS The Soundsmith Hyperion MR and Lyra Atlas SL @mijostyn If you use that formula using 1,000,000 instead of 1, you input R in Ohms, C in uF and the frequency is in Hz; IOW 1,000,000/RxCx2Pi You're using a digital crossover for the amps so you don't really need to passively roll them off, righ... | |
| 300b lovers The takeaway is that is impossible to "overdrive" the 300B. By contrast, a charmer like an EL84 can be driven with a whisper ... even a 12AX7 biased at 1 mA will sound good as a driver (which doesn’t work with any other power tube). A classic Mul... | |
| The Shure V15 V with a Jico SAS/B stylus VS The Soundsmith Hyperion MR and Lyra Atlas SL certainly in your system is happening and not a possibility with. @rauliruegas Its clear you misunderstood. When we were testing for 'ringing' it was on the bench using test equipment. I had thought that clear from my post but apparently not. L... | |
| Preamp upgrade I am wondering if the preamp upgrade for thousands more will provide any real marginal gain. @jelliott78 The short and long answers both involve 'yes'. Since your amps support balanced line, I would consider a balanced line preamp so as to get t... | |
| Open baffle speakers Also, I am of the opinion that when sound is coming from the rear and bouncing willy-nilly about the room, it may give a sense of depth to the soundstage but can’t really be good for imaging compared to a nice closed-back point or line source, or... | |
| The Shure V15 V with a Jico SAS/B stylus VS The Soundsmith Hyperion MR and Lyra Atlas SL To be honest, I haven't looked into the rationale for that. @lewm IIRC we were running a square wave through the cartridge and the loading was to reduce ringing. Unlike a LOMC, high output cartridges have a lot more inductance and (again, IIRC... | |
| The Shure V15 V with a Jico SAS/B stylus VS The Soundsmith Hyperion MR and Lyra Atlas SL @mijostyn Yeah, Shure claimed 1.2 gr was OK, but IME it isn't. Back then a number of cartridge manufacturers were in a bit of a competition to see who could get to the lowest tracking pressure, as they all seemed to think that was the major compon... | |
| The Shure V15 V with a Jico SAS/B stylus VS The Soundsmith Hyperion MR and Lyra Atlas SL @mijostyn You really need to track it a bit heavier- 1.5 helps it a lot. Also, loading it is paramount or it can be a bit in your face like any MM cartridge. If you don't load a MM cartridge, you really don't get to hear what they are about. If y... | |
| Do Harbeth speakers really need a 4000 damping factor? @ahal1 No, and no loudspeaker ever made does. | |
| Plasma Tweeters - Do they still exist? I heard a set of Tolteque loudspeakers at CES about 1990 or so. They were enormous and I marveled at how much work it must have been to get them to Vegas from France and then how crazy much power was needed to make them play; IIRC they were using ... |
