New Schroeder linear tonearm, any thoughts?
dave,Reverse engineering of protected intellectual property for commercial purposes is often actionable, though the legal complexities can be daunting. If the action is successful, the court may order injunctive relief (i.e., a "cease and desist" ... 
Ultrasonic Record Cleaner +++ New Model V-8 Clean
Etnier and Mjm_analog,Thanks for those links. This looks much like an ultrasonic RCM that John Chapman of BentAudio was beta testing 9-10 years ago. I *almost* got one, but John had to drop the project to focus on other concerns. BentAudio never b... 
New Schroeder linear tonearm, any thoughts?
+1 to Johnnyb53's post.@Frank - are you ready to retire on regular monthly royalty payments? I know some good IP attorneys. ;-)***Mosin, thanks for the props but you mis-spelled "discerning". Having just bought a new house, I'm now among the most ... 
Sumiko Blackbird Cartridge
"The repair shop says it is dead."What on earth does that mean? Snapped cantilever? Broken coils? Fungi growing inside?Have it evaluated by someone who understands and can work on phono cartridges (like Sumiko themselves or Soundsmith, as mentione... 
New Schroeder linear tonearm, any thoughts?
Why would there be any damage to the cartridge? Frank's moving pivot necessarily offers LESS resistance to longitudinal forces seen by the stylus than any fixed pivot. Any arm with a fixed pivot (including traditional linear trackers) offers 100% ... 
Scraping sound
Maxh,The suspension is collapsing under load. That much is clear. The question remains, why?There are two possibilities:1. The tonearm may be applying excessive vertical tracking force (VTF). This could cause the collapsing you described. It could... 
Desire upgrade but uncertain where to begin
Since you have a different phono stage sitting right there, why not hook it up and listen to what differences you hear? The best budget is "free", lol. Identifying what you like (or dislike) about one phono stage vs. the other will help you decide... 
TriPlanar Tips
Wrm57, Thanks for the interesting report (and for keeping his long-running thread alive). The rounding off you mentioned is very visible on the website, and of course any reduction in parallel surfaces will tend to reduce standing waves and feedba... 
Am I totally nuts or just a bit off?
Tonywinsc, by your own calculation, you're 44 drivers behind schedule! ;-)I was once ahead of it. Back in 1973 I had 18 drivers in my 2-ch setup... a pair of Bose 901s. In those days, Bose was pushing 901 owners to add a second pair, facing outwar... 
idler rumble, heat, and record wear--a connection?
I'd defer to any real scientist, but warming vinyl (up to some point which I don't know) might make it less susceptible to damage, not more. Cooling vinyl to below room temperature reduces its elasticity. Vinyl subjected to impact stresses in that... 
idler rumble, heat, and record wear--a connection?
Lew... that was a thoughtful reply. +1 
Gruv Glide - Do you use it?
I really can't see how the force of a stylus in the grove, which, considering the contact area, is probably measured in tons per square inch, could be "impeded" by anything. Hmmm... try diving off the Golden Gate Bridge. The landing is softer than... 
progress?
In one sentence: why in 1980 could I buy a turntable such as a Technics SLD2 for $130 and a cartridge such as an Audio Tecnica 12XE for a total of $160, while today I might spend $3000 and still not be able to track the Telarc 1812 cannons[when I ... 
Gruv Glide - Do you use it?
... I think it is a marvel on the VG++ and worse condition LP's that most of us have in our collection. Does knock back a lot of hash and background noise. IOW, it works by leaving a lubricating residue, which in addition to smoothing over any gro... 
About Lugnut -- Patrick Malone
Raytheprinter,Thanks for the reminder. Pat and I became friends here, if too briefly. We couldn't have differed more in musical and audio tastes and styles, but his good heart made those differences irrelevant.
