| Ultrasonic cleaning with kirmuss and loss of high frequency details. Bose, the enemy of SQ and truth in advertising. | |
| Ultrasonic cleaning with kirmuss and loss of high frequency details. I just Googled. There is a whole Wiki article on this subject. Seems the damage is manifested at the hair cells in otherwise young healthy persons. | |
| Ultrasonic cleaning with kirmuss and loss of high frequency details. Terry, "105db" at what frequencies? This issue of hearing damage from US RCMs makes me realize that I am not sure what part of the physiologic chain that results in "hearing" is damaged by prolonged exposure to high SPL in the audible range. Cou... | |
| First Turntable - Direct drive or Belt drive? My point was that since you already own an Ayre line stage, which is inherently a balanced circuit, you may as well also acquire a balanced phono stage. I say this also because most people with experience suggest that the Ayre products sound best ... | |
| First Turntable - Direct drive or Belt drive? Yep. Good old R0817 has apparently taken a powder. I'll miss his wit. | |
| First Turntable - Direct drive or Belt drive? Melm, the man already has good digital. Take a look at his equipment list.Also, the man has some money. The obvious fit for a phono stage is the Ayre P5Xe, which is a balanced circuit to go with the Ayre linestage. In which case it makes sense to ... | |
| Ultrasonic cleaning with kirmuss and loss of high frequency details. It might be subtly irritating to be around the US machine when it is in operation (via bone conduction and other ways we sense ultra high frequencies), but can your hearing be damaged by frequencies that are so far above the range of audibility? ... | |
| First Turntable - Direct drive or Belt drive? Omigod! Too many questions.To buy LPs in volume in order to start a collection, and unless you are very well off financially, I suggest you need to find a reliable source of used LPs. Best to buy direct from a dealer; don't buy off eBay. Fortuna... | |
| Ultrasonic cleaning with kirmuss and loss of high frequency details. There is a sort of "scientific" way to ask this question, if you have an oscilloscope or a very high quality AC voltmeter and the requisite test LP. Play some of the pure tone high frequency bands on the test LP, record the amplitude of the AC vo... | |
| Sussurro MkII and surface noise? Ditto for me with my Grace Ruby re-tip, using the OCL stylus. When it's good, it's very very good. Etc. | |
| Sussurro MkII and surface noise? If you ever do consult Peter Ledermann regarding your issue with the Sussuro please let us know what he says. He was very helpful to me when I had an issue with a Grace Ruby re-tip. And no one knows the sussuro better than he. | |
| Sussurro MkII and surface noise? Except setting azimuth with a mirror and any setting of anti-skate are inexact. Anyway VTA is where it’s at for this issue. Also I’d talk to Peter Ledermann. He’ll have the best advice. | |
| Sussurro MkII and surface noise? I am no expert on stylus shapes, but so far as I know, micro-ridge types are quite different from line contact types. Also, could you be leaping to conclusions based on only a few samples? Those of us afflicted with audiophilia nervosa tend to d... | |
| Forever turntable under $2000 Sleepwalker, The coreless motor in the new Technics turntables, even including the SP10R that was tested by M Fremer and found to be the most speed stable turntable that he has ever evaluated, derives from the first coreless turntable motor, inven... | |
| Any Hagerman Trumpet users have tube suggestions? Note that when I say depending upon the filament voltage, I mean that you will need to ask Hagaman whether the unit provides six or 12 V for the filaments. Then choose the tube accordingly as regards 6FQ7 or 12 FQ7. When I say the 6CG7 would requ... |
