| Anyone try the replica B-60 Fidelity Research VTA? Dear Lou:IMHO, analog audio today is saddled by more than a few unjustified myths and misbeliefs. These unfounded beliefs are fettering the progess that audio engineers are able to make, and are also preventing audiophiles from extracting the full... | |
| Channel Balance on Dynavector XV1-S Hi Moryoga: Changing the azimuth will affect the channel crosstalk, but will not accomplish much for the channel balance. A difference in channel output levels (balance) is better addressed with separate channel gain controls in either the MC head... | |
| Anyone try the replica B-60 Fidelity Research VTA? Dear Lew:I specifically replied to your statement:>The load resistor might affect frequency response but not gain.This is exactly backwards. The load resistance attenuates the cartridge output - the lower the load resistance value, the greater ... | |
| Anyone try the replica B-60 Fidelity Research VTA? Hi Nandric:>What is your opinion about the difference between the 'old-fashioned' FR-64 S and the (new) Ikeda IT-345?The FR-64S has a bit of extra resonant energy, a bit of extra spiciness that has been engineered out of the IT-345 (which was d... | |
| Anyone try the replica B-60 Fidelity Research VTA? Hi Lew: Since I have already written about this topic on the What's best forum, and a kind soul there was willing to convert my charts into gifs, I recommend that you read the following thread on the SME 30/2 turntable, from pages 3 to the end. Th... | |
| Anyone try the replica B-60 Fidelity Research VTA? Dear Lew:We are talking about low impedance MC cartridges, right?>The load resistor might affect frequency response but not gain.If so, wouldn't the MC cartridge frequency curves published in various magazines be non-comparable and essentially ... | |
| Anyone try the replica B-60 Fidelity Research VTA? Dear Nandric: You are the first person who has ever requested that I give them a heart attack (grin).>some old-fashioned machinist still swear by the old lathes and categorically claim that the talent of the machinist is more imortant then the ... | |
| JC3+ Anyone? I had a Delos customer who had problems with the Parasound JC3 - the high gain gave too much signal output, which would occasionally overload the preamp. He solved the problems by building a fixed attenuator and inserting it between the JC3 and th... | |
| Anyone try the replica B-60 Fidelity Research VTA? The Ikeda Sound IT-VTA-06 is a modern version of the FR B-60 elevation base, and made by the same guys who made the original.Although I have handled the IT-VTA-06, I haven't had the chance to try it out or compare it to the original. What I do kno... | |
| Dumb VTA Question Dear Bruce: I've used 10.5 inch (and longer) tonearms, and my experience was that the VTF and overhang errors introduced by SRA changes were significant enough that correcting the VTF and overhang did alter the sound. The real PITA is that you nee... | |
| Dumb VTA Question Dear Bruce: The SRA monitoring procedure is as Mofimadness stated.However, as I recently wrote in Stereophile, the construction of every tonearm that I am aware of (with the sole exception of the Eminent Technology linear trackers) guarantees that... | |
| Clavis Soundsmith retip Dear VPI:As mentioned in an earlier post (2010-01-10), we designed the Clavis' triple-damper architecture and elastomer formulations specifically to counteract a resonance / energy storage issue that was a low-level characteristic of the Clavis' c... | |
| Rega RP10 VTA shims Dear Theo: Lyra doesn't nominally provide a separate cleaning service, and heaven forbid were this the case! We are heavily backlogged in our production, and the single person who builds all Lyra cartridges is the same one who takes care of all se... | |
| Rega RP10 VTA shims Dear Theo: Your idea to get as close as possible with the ready-made 0.5mm incremented shims to validate the SRA trend, then follow up with a custom job, sounds like an excellent plan to me. Good thinking!I still recommend that when you have the c... | |
| Rega RP10 VTA shims Dear Theo: The Kleos was designed to have a vertical height (headshell underside to stylus tip) of 17.377~17.48mm with VTF applied. Let's say 17.4mm. I believe that the Rega cartridges are 14mm high, and Rega's tonearms and shims are designed acco... |
