| 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 ... | |
| Isolation transformer question @testpilot I'm skeptical there's any benefit if the equipment you're using has a competent grounding scheme. You always have the issue of pushing any isolation transformer past 50% of its rating- that does not change with balanced power. A good b... | |
| Isolation transformer question @clustrocasual Isolation transformers are incapable of cleaning up AC power. They can provide isolation, which is useful for solving ground loop problems, but they can actually add to AC power distortion. It is AC power distortion which causes s... | |
| FirstWatt SIT-3 or Pass Labs XA25 for Avalon Indras? @ulul 4 Ohms isn't a good load for the SIT amps and is marginal for the XA25. These amps are not high power and really are much better suited for slightly higher impedances since they tend to run warm- lower impedance loads (like 4 Ohms) will make... | |
| Need a modern Class A monoblock, preferably half or compact chassis Any idea what happened there? @antigrunge2 Sure- its the result of a vendetta. Take a look: https://www.audioasylum.com/forums/critics/messages/9/99823.html With established, respectable reviewers you get something different (scroll down for the... | |
| Power amplifier longevity… thoughts? @audiofilo123 I'm using my own (Atma-Sphere). There are others that are getting similar comments, such as the AGD Audion. | |
| Speaker wire impedance? Speaker impedance? @immatthewj To the first question, yes. If you were using a Radio Shack meter then you were seeing readings no lower than 0.1. |
