| Fun with MM cartridge Chakster is not giving away his NOS ATML-170. That's for sure. | |
| Vinyl playback - lack of bass? I haven’t “confused” anything. I was referencing early production cdp’s. I thought I said that. Also, of course the term “brick wall” is a metaphor for very steep slope. I probably was remiss in not acknowledging that SACD and DSD ameliorated the ... | |
| High Performance Moving Iron Cartridge Candidates? I’m actually using chewing gum on the headshell of my Reed 2A, in order to counterbalance my Dynavector 17D3. | |
| Hagerman Piccolo Zero: New transimpedance head amp Ohm already told us that voltage/resistance = current. Why complicate the thought process with a term like “magnetic efficiency “? If in building a LOMC you use a sufficiently powerful magnetic field and as few as possible turns of wire in the co... | |
| Turntable to Phono to Pre connections Wow! It’s tough to sort out all the different concepts contained in the above posts. An RCA IC can be used to carry a balanced signal, BUT not a good idea if the "ground" conductor, which becomes the negative phase in a balanced circuit, is carri... | |
| High Performance Moving Iron Cartridge Candidates? It’s always easy to add mass to any tonearm. Low effective mass is never an insurmountable problem. Also, to be clear, it’s high output MC cartridges that I haven’t liked, not high output MIs. The latter are most of my favorites of all time: B&... | |
| Vinyl playback - lack of bass? bbarten, To answer what I think was a question, yes, the RIAA curve is the industry standard for recording and reproducing music on vinyl. All modern phono stages to be used with magnetic cartridges contain an inverse RIAA filter in the signal pa... | |
| High Performance Moving Iron Cartridge Candidates? I think PL was influenced to get into MI cartridge development and manufacture by his prior experience with top of the line B&O cartridges, like the MMC1 and the MMC20CL. So he first developed the SMMC line of SoundSmith cartridges, which he ... | |
| Vinyl playback - lack of bass? Because digital has a brick wall filter at around 22Hz, the response stops dead at the frequency. Harry Pearson first noticed that at least early CDPs lacked what he called "downward dynamic range", perhaps because of the filter effect. After HP... | |
| High Performance Moving Iron Cartridge Candidates? Jason, read what you wrote. Don’t you think your generalization is at best flimsy? | |
| Source of Fremer's "1 arc second" claim? All of the EMs at the National Institutes of Health are in the basements of the various buildings that house them. The one in our building was not further stabilized by any sort of air suspension. Yet it was stable enough to permit visualization o... | |
| Durable record vacuum cleaner recommendation? What I do with the HW17, because I find that a distilled water rinse is worth the effort, is to wash with cleaning solution dispensed from the tank via the brush, scrub in both directions with brush, then vacuum, then rinse with distilled water fr... | |
| Vinyl playback - lack of bass? If anything, I always thought that Rega's design philosophy, ultra light weight minimalist construction with emphasis on rigidity and structural strength, might possibly result in a slightly reticent bass response. No matter what is the cause, eve... | |
| Source of Fremer's "1 arc second" claim? Yoyo, It seems you are insisting there must have been a difference that would be clearly evident to keen audiophile ears, when MF had to listen to the Wilson Benesch TT without the ThorLabs base. How can you possibly know that unless you were at ... | |
| Fun with MM cartridge 11. Very hard to find a real one. I haven't hunted voraciously for one, but I do hunt other vintage cartridges in the usual places, and I cannot recall ever seeing one for sale. |
