STC Posted January 25, 2018 Author Share Posted January 25, 2018 VAC 3070 mono power amp. This one is difficult one as the manufacturer ignored request for schematic. That's why I love Classe products. They provided schematic except for their current model still under warranty. ST My Ambiophonics System with Virtual Concert Hall Ambience Link to comment

Incidentally, the John Curl Blowtorch Preamp part 2 Thread in DIY Audio , now has almost 100,000 replies !!! Click on the image twice for a much larger image. I can't believe that anybody is taken-in by things like this. All cases like this do is triple the price! You're not just paying for the aluminum that 's in the case, you're also paying for the aluminum that they machined away as well! This is what's wrong with the high-end. Useless bling that does nothing to improve SQ, It's just there to drive the prices up. I've often thought that equipment should be sold two ways, in sturdy, utilitarian enclosures (like the kind Schiit and Audio by Van Alistine uses) and if the buyer wants to pay for it, excesses such as the (admittedly beautiful) case machined from a single billet of aluminum as shown above. So many of the pleasurable things in life have been pushed out of the reach of the average hobbyist, things the average Joe Working Stiff used to be able to afford: Sports cars, private planes, nice cabin cruisers, sail boats, etc. Now the greedy among us want to push audio completely out of the reach of the average would-be audiophile as well. Then the pundits of this hobby lament in print about how we don't get many young people coming into audio! When I was a teen, One could buy a decent stereo amplifier as a kit under $40. Decent (for the times) speakers for about the same. An AR turntable was $70 and a decent magnetic cartridge from Shure, Pickering, or General Electric could be had for $10 and a stereo FM tuner could be bought from Eico, Dynaco, Heathkit, or Knight for $40! That system, by the standards of the day, provided damn good performance, and super value. Now, of course, if one had a little more money, but still reasonably priced,they could buy finished amps and tuners from H. H. Scott, Fisher, Marantz, Sherwood and McIntosh. A pair of Dynaco MKIII 60 Watt/channel power amps could be built, from kits for just a tad over $100, a Dynaco Preamp, the PAS3X could be had for under $50. H. H. Scott sold kits, nice ones too; as did Harman Kardon, and the stuff was quality for the period. Even in the 70's every college kid was able to buy a decent receiver from Japanese companies such as Pioneer, Sony, Panasonic, Technics, Sansui and the like and a pair of OK speakers from AR, Infinity, or Dynaco to go with them as well as a sub-$100 direct-drive turntable to complete the system and the stuff sounded OK. But the point was that average people could afford it, and the kid who started modestly when young could buy better and better equipment and still not be priced out of the market! Bah!, these price trends make me sick and it's bling like the case shown above that makes equipment so expensive, and causes your average young music lovers to stick with their iPhones and earbuds while making fun of our audio hobby! Can't say I blame them much! Sorry about the rant! STC 1 George Link to comment

I don’t see anything wrong with their approach. Some audiophile prefer these kind of designs for better vibration control. Audiophile is is a very small community. It is a hobby of obsession of equipment and solving the puzzle the hard way. There is is a demand for it. Just like some people who prefer to $10 for a cup of coffee that can be bought for $1. It is Not the coffee that matters to them. Same thing with audiophiles, it is not the music but the obsession of the way they reached there.

Sam Lord Posted January 27, 2018 Share Posted January 27, 2018 A stereo microphone preamplifier with a single power transformer, yet with *unmeasurable* crosstalk: < -140dB at 200kHz. Try to match that. STC 1 Mac Mini 2012 with 2.3 GHz i5 CPU and 16GB RAM running newest OS10.9x and Signalyst HQ Player software (occasionally JRMC), ethernet to Cisco SG100-08 GigE switch, ethernet to SOtM SMS100 Miniserver in audio room, sending via short 1/2 meter AQ Cinnamon USB to Oppo 105D, feeding balanced outputs to 2x Bel Canto S300 amps which vertically biamp ATC SCM20SL speakers, 2x Velodyne DD12+ subs. Each side is mounted vertically on 3-tiered Sound Anchor ADJ2 stands: ATC (top), amp (middle), sub (bottom), Mogami, Koala, Nordost, Mosaic cables, split at the preamp outputs with splitters. All transducers are thoroughly and lovingly time aligned for the listening position. Link to comment
