  1. ASIO and USB are not mutually exclusive - see this panel from my system If you select the driver for a device that is not connected Foobar will usually timeout. A USB DAC driver will not drive your soundcard anymore than it will drive a scanner or printer. Why not connect the DAC by USB and save all this grief ?
  2. If the DAC is not connected by USB the computer does not "see" it and drivers are not required. (nor will they do anything) It is just the same as if you connected a CD player to the DAC by SP/DIF. If you see ASIO drivers for your soundcard in Foobar then select them, selection of Digital output will be in the Asus control panel or windows sound settings. If you cannot find Windows 10 ASIO drivers you may be able to use Windows 8 drivers in compatability mode.
  3. I would not say that a clamp or puck were necessary, but, IME the combination of one with various different mats may provide changes to your perception of various replay characteristics. They provided me an opportunity for trying various combinations until I found myself with a combination that satisfied my tastes. Their effect will also depend on what the deck is placed upon for support. On my modified P2 with GT platter and sub platter and SRM "silent base" I found the combination of a Funk Achromat and a Bren1 puck gave the result I was most satisfied with and I used that combination for many years. If the puck is placed gently on the record such that there is no shock load on the bearing there need be no concern on that account. You may find it interesting and instructive to experiment for yourself, I certainly did. I would also note that I do not follow RG's advice to allow the stylus to clean my records, not all his pronouncements need be read as gospel.
  4. Better known in pro audio circles perhaps, these are a life time investment. I bought an SM3 in the early nineties from studio 301 when they were moving from the city, it still provides sterling service in a friends system today with nothing needed in the way of service since I bought it. MM & MC inputs with high and low gain and sockets for load plugs. If remote volume is a real must have I would be checking the internal space very carefully as it looks like a motorised pot and control board could be fitted without much hacking. Really good buying here folks.
  5. As a reference please read the EML datasheet on the 274B rectifier tube and note the capacitance values there. This does not take into account any other variations there may be in your design which may possibly use a hybrid scheme (partial tube and SS rectification). For a completely tube rectified circuit pay particular attention to Note 2 at the bottom of the datasheet. I might be tempted to think that an EML rectifier tube could be a worthwhile upgrade provided the circuit values will not compromise it. I like the EML tubes in my Yamamoto amp.
  6. Not to put the dampeners on proceedings, but the little I do know about tube amp design suggests that increasing PSU capacitance in a tube rectified circuit is not to be undertaken lightly nor without complete understanding of the whole circuit and the effects of such change. Rectifier tubes can be overstressed by too much capacitance following them, chokes and hybrid rectification schemes can affect the desirable values too, but the take away is that increased PSU capacitance is not necessarily "a good thing" and that it needs a very competent valve tech to vary the values to any benefit. Otherwise, agree with Muon that changing out the AB resistors may lose some of the designed "flavour" - still have fun with it all anyway.
  7. The DX3Pro is also available through Amazon if that is your preference. A good headamp section with plenty of drive and a DAC that did not embarass itself when compared to an iFi iDSD Micro Black Label.
  8. Not sure what or whom you might consider to be "dodgy overseas" sellers. I recently purchased a Topping DX3Pro direct from these folk for an acquaintance and found them to be prompt and responsive. It sounded more than acceptable to me and I do own much more upmarket gear. Shure SRH 940 from StoreDJ will pair well with it, although I preferred my open back ATH-AD1000X which worked really well with it. I am partial to AT cans generally though. The Shure are very even handed if a little more prosaic.
  9. Would that be Cmoy perchance ? - those I have heard of.
  10. From the photos it would appear to be the DL-103 version.
  11. They are getting close to their target but only 2 days to go. Maybe I am the only one here who thinks they are worth supporting but please give them a listen. Some samples from the proposed release are now up on https://www.pozible.com/project/crooked-fiddle-bands-3rd-album/updates They have been live gigging for a good while now so they must appeal to some folk apart from weird old gits like me.
  12. Just putting it out there, the Crooked Fiddle Band from Sydney are planning a new album and are looking for funding pledges to complete the work. Campaign page is at https://www.pozible.com/project/crooked-fiddle-bands-3rd-album/ Check out their previous work on https://crookedfiddleband.bandcamp.com/ I suggest listening to more than one or two tracks as there is quite a variety amongst their output. I have enjoyed their work and thought it worth supporting, perhaps some of you will too.

  14. If you really want to drive yourself to distraction you could get a copy of https://www.amazon.com/Critical-Listening-Skills-Audio-Professionals/dp/B009CUSFE2 Don't be put off by the absurd price - look at the secondhand listings. The book comes with a CD of examples that you walk through with the lessons in the book.
  15. Seems you rarely pass up an opportunity to bag the Elevator Exp either - is there something personal in that ?
