| Who needs a MM cartridge type when we have MC? Chakster,"It's a bit shoking price for me as i have one NOS Astrion myself, but i don't have the right tonearm for this cartridge. It was in the Raul's list of interesting MM cartridges in the beginnings."You were right the first time - don't have... | |
| Vintage DD turntables. Are we living dangerously? An update on the lead under-mat project. I've determined the lead sheet I'm using is not completely flat. This is made from flashing for roofing. I don't know about other types of lead sheet.I think casting a lead mat is the way to go, but I haven... | |
| Vintage DD turntables. Are we living dangerously? Dover,Can't say I accept your anecdote about the Studio as being typical of performance. I've heard a few and your description of "lurching around" suggests a malfunction or improper set up. I no longer own a Goldmund so I have nothing to defend, ... | |
| Vintage DD turntables. Are we living dangerously? Lew,When Lurne was working under contract for Goldmund I imagine there were constraints. The T5 linear arm wasn't held in the highest regard and the DD suspensions were problematic with any arm substitution. Many users including myself defeated th... | |
| Vintage DD turntables. Are we living dangerously? Last month Lew brought up an aspect of performance that we read little about, speed correction timing."It's also the case that the L07D servo was deliberately designed to exert a much looser control on the speed than does the Technics servo, for o... | |
| Vintage DD turntables. Are we living dangerously? Dover,Interesting impressions of spiked mats. I'll keep that in mind, although you repeat yourself. Once should be sufficient?" their goal is to dump excess energy from the stylus/record interaction to ground as fast as possible."Exactly how is th... | |
| Vintage DD turntables. Are we living dangerously? "What are the measurable physical properties of lead that could support the contention that it is superior....."Weight, density, damping coefficient? We're talking about the transmission of vibrations through a material(s), and this stuff isn't ex... | |
| Vintage DD turntables. Are we living dangerously? Dover,I don't doubt your results. They are what they are. It's the explanation that doesn't add up. The Goldmund platter is designed to match the mechanical impedance of the record with the surface adjacent to it. A steel or copper surface directl... | |
| Vintage DD turntables. Are we living dangerously? Nope.....Doesn't add up. The Goldmund mat was about 3mm and close to the mechanical impedance of the record. Vibrations pass through relatively unimpeded and the aluminum (usually) platter would reflect them back to the record. The mat will only t... | |
| Vintage DD turntables. Are we living dangerously? Aigenga,"On the subject of platter mats I just want to re-iterate that I am using a lead mat glued to an Achromat. I thought that Fleib or someone else was about to try the same thing and wonder how that worked for them?"I'm experimenting with thi... | |
| Phono stage w/automatic Load-Impedanance. On 6/3 and 6/4 it might look like I was clarifying Atmosphere's response. My posts were delayed for 4 or 5 hours on those days. When I wrote them, there was nothing to clarify. They hadn't yet appeared.I'm not saying this to be contentious, but th... | |
| Phono stage w/automatic Load-Impedanance. Dave,The cartridge is not physically generating at these frequencies. It's an electrical resonance at a particular frequency which can cause overload or oscillation. This occurrence will also intermodulate and affect the mid/high frequency range w... | |
| Phono stage w/automatic Load-Impedanance. " IntactaudioCan someone please tell me how this resonance in the MHz range is being excited?"The output of a cartridge has inductance as a property of that output. If you draw the circuit, the voltage of the cart has its self resistance and induc... | |
| Phono stage w/automatic Load-Impedanance. *The above comment was from jcarr, which seems to agree with what Atmasphere is talking about.*Even if you agree with JCarr and Atmasphere about Lyra, does this apply to all carts? What about those which are underdamped? Once again, this thread is... | |
| Phono stage w/automatic Load-Impedanance. Atmasphere, From this thread:*In the absence of noise one might prefer to load down a MC because of preference. Damping a cantilever/generator might improve focus and detail, while wide open might increase stage and size.**A phono cart is an elect... |
