Clearaudio Double Smart Matrix or Loricraft PRC4
Randy,We use a handheld small tools demagnifier, sold through industrial supply houses. There are many out there, ours cost ~$65 IIRC. I'm reluctant to post a link because ours was TOO cheap (a product of China, and not their best work). It gets h... 
Clearaudio Double Smart Matrix or Loricraft PRC4
Dan, You've seen our clean-me-now pile in the LR and that's barely a tenth of it. As Peter says, for throughput compared with wand style machines, a Loricraft can be part of the problem, but not part of the solution. Vacuuming alone takes ~1 minut... 
Schroeder Reference Arm
Frank,No reason for hard feelings between you and us, and happily there are none. For clarity, please note that there is no conflict between attempting to "(pseudo-)objectivly assign qualities or the lack thereof to certain design features" and "p... 
Schroeder Reference Arm
Heh. Mr. Weiss had no problem believing every word Paul and I spoke when we offered positive analytics in his room during RMAF 2008. No snide remarks then!Today, in an ill-judged defense of his commercial positions, he disparages components he's n... 
Azimuth and the Fozgometer
Of course, it is minimizing crosstalk at only one test frequency (1 kz on the Analogue Productions test lp), unless one finds other test lps with single channel signals at other frequencies. Two reasons in one sentence why some of us will probably... 
Clearaudio Double Smart Matrix or Loricraft PRC4
FWIW in response to some points made above:1. We've owned and used a PRC3 for 5-6 years. In all that time I have only once had the thread bind up in the tube. That was less than a year after we bought the machine and I blame operator error. We've ... 
SUT shootout
Obviously hearing a wide soundstage from a mono recording would indicate a system problem. Further, only a fool would expect any sort of soundstage from multi-miked recordings made in 15 seperate booths, in takes spread over three weeks, all mixed...

Lew,Please continue to bother. Many bumblebees do fly, just not those particular bumblebees!The SG was not one of those two examples, obviously, though FWIW Paul actually did predict its specific sonic character before we heard it at RMAF 2008. It... 
rumble issues - see old thread update
Koegz,All ported speaker cones oscillate when air inside the chamber is energized at the port frequency. When air is compressed at the port waves flow back into the cabinet at that frequency. Something inside has to move and the easiest thing to m...

Rccc,For clarity, I don't think its helpful to consider resonances in a tonearm in this context. Stray energies leaking from a cartridge can cause problems whether the arm resonates or not. Intra-arm resonances would indeed be a problem, but lets ... 
rumble issues - see old thread update
Hi Tom,As you know we use the same arm, cartridge and preamp. With 8-10 different UNIverses on our arm we've never had such issues with any music, at any volume up to window shattering. Based on that experience I question the tonearm/compliance th... 
TWL fishing weight mod for Rega RB600 arm
I'm confused. Does this DP-59L have an RB600 or the stock Denon arm? If it still has the stock arm, why mention the RB600? TWL's HIFI Mod was for the RB250 and its clones, not the RB600. I mounted one of his earliest mod packages on an OL Silver (... 
SoundSmith Counter Intuitive For VPI Arms
Stringreen,Here's a link . It's actually a clever tweak for JMW arms that provides repeatable fine tuning of both VTF and azimuth, without moving the main counterweight. It's like the (dirt cheap) O-rings I recommmend for arms without fine VTF, b... 
SUT shootout
Al, a few quibbles (it's what I do!)...No normal cutting lathe could cut a square wave and no playback rig could trace one. You certainly wouldn't find me trying with my $4K cartridge! A square wave would be useful but perhaps it's not essential, ... 
SUT shootout
The shoot out results are more about the cartridges likes than the actual transformers abilities.Exactly right, and Vinyljh only mentioned half the issues. As fun as this shootout was, there was no mention of impedance loading of any of the SUTs, ...
