| A Few Turntable Measurements using the RPM Android App Thanks for the discussion, @kevemaher . | |
| Grado Epoch 3 With more careful setup, the Epoch surprises with yet better results. Azimuth correction is very low, less than 14 minutes of arc counter-clockwise. Tail down at 15 minutes of arc gives a delicious, mellifluous tone to everything from Arvo Paert t... | |
| A Few Turntable Measurements using the RPM Android App @kevemaher I agree that wow, flutter, and rumble measurements are quantifiable and repeatable and agreed upon. I think, however, that this is not the whole story and that a 50KHz sampling rate would give us the data needed for a more robust analys... | |
| How to prevent visitors from touching your system On the way into the listening room everyone has to pass two full size racks for (electric) power supply and compressed air. Both are covered in meters, dials and lights. I tell them how much energy is controlled in each cabinet, and for some reaso... | |
| A Few Turntable Measurements using the RPM Android App @kevemaher With all due respect, keve, I think that you are putting the cart before the horse. Before one aggregates observations, one must make observations. The difficulty with making speed observations is that for practical purposes they mus... | |
| Picking Speakers 20k-30k @larryi You write, "Maggies ... sound quite good when placed closer to the side wall than recommended, but, they do need space to the wall behind." Agreed, that’s where they sound best. But I put my Magnepan Tympani 1a’s, which were 6’ tall and 4... | |
| A Few Turntable Measurements using the RPM Android App As is often the case, measurement is the issue. RPM is a continuous quantity only in the abstract. In all practical applications, it is an average. Maybe over a fraction of a millisecond, but that still is a far cry from continuous. So the major ... | |
| Grado Epoch 3 Mounted the Epoch on a my new ultra-damped natural fibre wand, and boy, does it sound good. From the first needle-drop the sound was obviously cleaner, weightier, and more dynamic than I had been used to. Tracking is sensational. The bass tremolo... | |
| Picking Speakers 20k-30k Consider Quad 2912’s and Magnepan 30.7, augmented by Magnepan auxiliary DWM bass panels. I use a pair of Quad 2805’s perpendicular to a pair of Quad 2905’s, and two auxiliary DWM panels for a fast, seamless sound. But if you like to play loud, be... | |
| it is fake or real transiator? Sometimes. As mentioned, the lettering is sometimes different. Also, pictures of the parts may indicate prior use or even hard use. Then there is cost - if it looks like an amazing bargain - maybe it isn’t such a bargain. You could ask the seller ... | |
| it is fake or real transiator? Unfortunately, fake transistors do happen, especially for good or expensive transistors. Often the lettering is a give-away - so find an example which is known to be legitimate and compare with what you have. Next, try running it at near highest r... | |
| Canare 4S11"G" now available! Thanks for the note, @mofimadness . Always nice to have options from a first class source like Canare.. As I understand it, oxygen changes the crystalline structure of the copper cable. OFC has fewer crystal boundaries for the signal to cross. I... | |
| Perfect Vinyl Forever @wolfie62 You write, "So your ASSUMPTIONS about my unit are way off base! " I made NO assumptions. I shared three possible reasons for your getting different results. Why so angry? Why so defensive? And again, "You don’t have the expertise to ... | |
| Perfect Vinyl Forever @wolfie62 Dogberry is right. US can't cure abused records, but US gets the most from the records you have. I run a high power lab unit at 80KHz, 2 records at a time. If you fill a low power unit running at 40 KHz with 10 records, you won't get m... | |
| Grado Epoch 3 It's really interesting to hear your thoughts on how the Epoch's sound changes with use. After 300 hours on the Koetsu it sounded glorious, so I foolishly decided to use a 'flux-busting' record to "improve" it. All that happened was that the soun... |
