| Does anyone care to ask an amplifier designer a technical question? My door is open. Thank you for your kind offer, Roger.I build solid state amplifiers, and like to match output transistors. At first I matched for HFE, then VBE at constant current similar to operating spec. Only later did I realize how much this parameter drifts ... | |
| Your Forever Pieces? What and Why? Koetsu rosewood signature platinum with diamond cantilever. Very subtle, very refined, VTA adjustment takes it from analytical to romantic.Most of my DIY stuff. | |
| The urge to tinker is awash. What TT might better mine and why? Both my TT use the Trans-Fi arm, which is going back into production. | |
| The urge to tinker is awash. What TT might better mine and why? Why not stay with Tom Fletcher's sound?When I heard the spacedeck (1997), I ordered the Mentor (now Dais). It is notably superior. Pear Audio is also a Fletcher design. I also have the Wave Mechanic power supply - another improvement.IMO the tonea... | |
| Any good reasons to use transistor phono stage and line level preamp instead of tube ? Positron tubes are hard to come by. At least, harder than PNP transistors. | |
| ETI Research Cable Pods any one recommend this? I use them in DIY, on all 6 of my monoblocks. Also ETI RCA connectors.I also use WBT on my Quad ESL's. These are also good, but are more costly. I can't say whether either of these make an immediate improvement (maybe they do, maybe they don't). B... | |
| If you could just pick one instrument that you think sounds best on your speakers Voice, especially Faure's Cantique de Jean Racine, played on an array of Quad 2905's (heavily modified: Plitron transformers, air gap capacitors, disabled protection circuits). The array of multiple speakers makes any volume easy without overdrivi... | |
| Specific question choosing Duelund vs Mogami for affordable interconnect Heresy alert: depends on your electromagnetic environment.If you get good cel phone reception, or there are radio or TV transmitters nearby, chances are that you have a lot of electromagnetic radiation in your environment. Some cables may act as a... | |
| recommendation for speaker wire to soften the highs if possible ieales has some good suggestions too. Lots of soft things in the room, like carpets, can help. | |
| recommendation for speaker wire to soften the highs if possible I suggest thinking of your audio system as a whole. Something is causing harshness. There are two ways to treat that.First, as Elizabeth suggested, attenuate the offending HF with ferrite beads. Cheap, easy, and probably effective, unless your spe... | |
| Platter mat insanity @slaw I use a custom spindle for the air bushing (thrust and radial air bearing), which supports a cast iron platter and the graphite mat on a machined stainless taper. Part of the design is an extension of appropriate length to serve as a record-... | |

| 'Diamond' cantilevers: a man's best friend? I have been in love with the Koetsu sound since 1976, but my first one was a gift from wife a few years ago: Rosewood Signature Platinum with diamond cantilever.The cantilever and stylus are ground from one piece of clear white diamond. So it is p... | |
| Platter mat insanity My search stopped with graphite. I use a 1" slab of graphite atop the platter, like Nottingham Analogue (Tom Fletcher design).Does two things - couples to vinyl, and deadens the platter. | |
