| Which vintage direct drive? I too use a Trans-Fi. Actually, two of them. Both on belt-drive turntables which are directly coupled to a slate table and thence to concrete and bedrock.Suggest that you consider belt drive. I tried a quality vintage DD, and it was notably inferi... | |
| US source of Panzerholtz? OH - now I think I see what ASC is talking about. Perhaps they are talking about vibration THROUGH the wall material, whereas what we are interested in is vibration ALONG the plinth material.All the same, I wouldn’t want my walls flexing like a 10... | |
| US source of Panzerholtz? Agreed that constrained layer damping works by converting vibration to heat, but don’t agree that it is more effective when both layers are less stiff.A counterexample to the ASC assertion is industry-leading Quietrock 545 acoustic drywall, with a... | |
| Going Battery Powered I use batteries for my DIY phono/pre. It’s black, and I would not go back. I use 120VAC power for the DIY amplifiers with very fast and very quiet bridge rectifiers and LCLCLC filter circuit. A hundred kilograms of inductors and a Farad of capacit... | |
| US source of Panzerholtz? I used panzerholz B25 for my DIY TT plinth. Agreed, hard to work with, gummy (the glue) and hard (beech veneer). I did most of the cutting with a jig-saw (German blades) and file, and a diamond hole saw. Takes a good finish.The thing is, it's acou... | |
| Bryston or Aragon Owned three Bryston amps before I began to DIY. Recommend them highly - good, bullet-proof design, good implementation, unbelievably good customer relations and service.Bryston is one of the best companies out there. | |
| Upgrade cartridge or turntable? Miller is dead right about the look and feel. I use top line vintage test equipment like oscilloscopes and signal generators just because they look and feel better. It makes a big difference when you look forward to fiddling with things, rather th... | |
| Upgrade cartridge or turntable? According to expert advice I ignored in my youth, turntable first, tonearm second, cartridge third. I ignored this advice, to my cost. For one thing, turntables and tonearms don't wear out.Another thing to consider is bang for buck. There is a ton... | |
| Please Make Audiogon Cool "If there are actual degreed electrical/engineering physics/acoustic engineers and degreed physical scientists, please speak up"Well Robert, as a math type I find that some degreed engineers are among the hardest to take. They seem fond of quoting... | |
| Sturdy Turntable Stand DIY: Baltic birch carcass screwed and glued to structural posts, 3 x 3/4" bb layer under solid slate slab, all assembled with elastomeric glue (Chemlink M1). Nearest thing to a concrete pillar. | |
| Who needs a Diamond Cantilever...? 💍 I own the Koetsu Rosewood Signature Platinum with DC. Gift from my lady. Speed and brilliance without glare or astringency. Have never heard a cartridge like it, and although the Miyajima Zero is awfully good, it lacks the ultimate refinement of t... | |
| Warm up time for amps Do you need heat in the winter? Use your amps instead!I leave my class A's at one third power most of the time, and go to full power an hour or three before listening. I have found no difference between running at full power with a signal and runn... | |
| Phono cartridge suggestions sought Don’t know if this will work for you, but I adjust azimuth by finding an undamaged record which sounds noticeably better on one channel than it does on the other.Some of the Harmonia Mundi choral selections with strings have this characteristic on... | |
| Thumbs up for ultrasonic record cleaning @jtimothya It's only cleaner in terms of suspended solids, not in terms of soluble compounds. As Slaw notes, the yellow color fades to brown with use. After about 100 records, I change the chemistry. Arbitrary, but probably on the safe side. | |
| I need some turntable guidance Set-up is critical.A well set-up mid price rig will outperform a poorly set-up state-of-the-art.That suggests buying from a dealer who is really good at set-up. They exist, but you have to search. Identify them by asking about azimuth, VTA, protra... |
