  1. I'm currently using one of these on my reasonable PC speaker setup. It probably is a bit excessive but it sounds fantastic. GLWS.
  2. Further information: This diminutive little preamp offers ultra low distortion, decent gain and features such as 4 inputs and a chunky little metal remote that adjusts volume and selects input. Totally silent operation as it is a chip based attenuator (PGA 2311). I bought this about 3 weeks ago to test it out in my home system. I am selling it because it doesn't seem to match my system. It goes from -90dB of gain (silence) up to +31dB of gain (which is a lot). When I get past 10dB on my system I am getting a lot of distortion. I probably need about 20dB to get my amplifier
  3. Further information: These are very nice Ethernet Cables which use Cat 7 VIABLUE EP-7S (solid core OFC conductor) and very substantial LINKUP connectors (metal shielded body, gold plated contacts, screw on cable inlet). Total length is 1.5m each (just over actually). Finished in genuine Techflex Carbon sheathing. The grounding on these cables reflects the JSSG360 (John Swenson) philosophy of being connected at one end (the one with red heat shrink) and not being connected on the other (black) end. Try running the grounding to either end of the connection in your set
  4. Further information: Just to explain what this is. PS Audio had their LAN Rover USB "extender" which essentially packetised the USB input and sent it via ethernet to an output at the other end. The benefit (apart from being able to send USB over really distances) what there there was galvanic isolation between the source and your DAC. It was widely known at the time that the LAN Rover was out that PS Audio in fact used rebranded version of the Icron USB / Ethernet extender. This unit has some improvements over the LAN Rover and the older Icron unit because it uses Fibr
  5. Further information: Up for sale, Supra CAT8 cable with the audiophile go-to Telegartner MFP8 T568A connectors. I used my favourite Techflex Carbon sheathing which looks pretty good over the Supra Ice Blue cable. Length is 1.7m. The grounding on these cables reflects the JSSG360 (John Swenson) philosophy of being connected at one end (the one with red heat shrink) and not being connected on the other (black) end. Try running the grounding to either end of the connection in your set up to see (hear) if there is any difference. Cable has been tested. E.G. https:
  6. Right click "paste as plain text" should work (CTRL SHIFT V is the windows shortcut)
  7. Further information: The illustrious SOTM200. A bespoke mini computer that does one thing and one thing really well - stream hi-res audio via ethernet and output in via USB. Roon compliant (I had to update the firmware recently as the new Roon 1.8 update seemed to make Roon think that the SOTM200 wasn't compatible any more ). Also has it's own bespoke operating system - connect it to your network and the device appears in your web browser so you can access the settings. Its deceptively simple. A massive step up from a Laptop or PC based music output. The SOTM200 has a
  8. Further information: This is a great little unit that I bought after reading some measurements on. It has 2 functions, one to act as a buffer that uses Jfets to provide a high input impedance and low output impedance and to provide a very accurate attenuation of source. The other function is where you switch off the Jfet section and use the relay volume pot to provide attenuation. In that function it is as benign a passive buffer / attenuator as you could hope to get. And it has remote control, multiple inputs and dual outputs so it's covered in terms of convenience. I r
  9. It's vaguely Yaris shaped but that's where the similarities end
  10. Ze blurb " Acoustid to listen to your songs and find matches even when they have no information at all, but also takes advantage of existing file information to ensure you get the best album match. SongKong uses our own dedicated JThink Music Server regularly updated from the MusicBrainz and Discogs databases giving you more accurate matches, faster." It took me SOngkong 12hours to go through my entire collection (lots of tracks) but it certainly improved my experience.
  11. Songkong by Jthink is good - I own it: http://www.jthink.net/songkong/ Also this might be worth trying - https://www.blisshq.com/organise-music-files.html ??
  12. For mid-bass (not deep bass) and for testing if a system has good accuracy in that region (not just loud mid-bass!), Dire Straits Ride Across the River.
  13. Further information: Up for grabs X4 1.2m Ethernet cables. These are used to run connections between patch panels in Datacentres. Theses U/UTP cables have 10GX certification which ensures a very high resistance to EMI/ RFI and Alien Crosstalk. A good short length for small spaces too. https://catalog.belden.com/index.cfm?event=pd&p=PF_10GXFUTPCMRPATCHCORDS Photos:
  14. Further information: The USBridge Signature Player, a small form streamer with a very high quality USB output. Includes an SD Card with the latest version of DietPI with the Allo interface. Connect to an ethernet cable, start it up and then go to http://dietpi.local to start using it. if you are using Roon, simply select Roon in the list and then find the streamer in Roon - and away you go. https://darko.audio/2020/06/allos-usbridge-signature-review/ "Flexible, reasonably priced and sounds excellent. What’s not to like?..." * WIFI dongle is not includ
  15. Might want to check your pictures. They show a pair of Behringer A500's. Not Sampson amplifiers.
  16. Nothing new to learn in the world of acoustics then. Sorry for wasting everyone's time.

  18. I always found the bass in my the XA100.5 that I owned, then subsequently the XA30.8 to be the weakest point of their sound. Subjectively it's a very pleasant, fat bass which I think would be favoured by tube lovers and may be where a lot of the tube-amp comparisons spring from. I listen to a wide variety of music, and a good bit of electronic stuff so I was attracted to the faster, tighter bass from the XA25. I think damping factor (or output impedance if you want to look at it from the flip side) are the main factors here.
  19. Wow take a chill pill. I didn't read any sarcasm in that response and I thought it was a poor comparison, not to mention we're veering off topic. Must be that dodgy MGB steering.
  20. ME1500 to the bass drivers and Pass Labs to the rest??
  21. No, sorry but that's misquote:https://www.passlabs.com/wp-content/uploads/2020/05/x3_om.pdf "The supersymmetric amplifier is a special subset of balanced amplifiers, unique and covered by U.S. patent." The Pass Labs stuff can run quite well on 2ohms -https://www.stereophile.com/content/pass-labs-xa305-power-amplifier-measurements I was actually was running my XA25 on 1.5ohms for a while. Not knowing that one of the bypassed capacitors had shorted in my midrange driver on one side. I worked it out as it was cutting the one channel when I was driving at about 95dB+. Otherwise, it
  22. I must be half asleep. Of course you've seen that data, you contributed to the thread. 😬 DATs also gives you a phase angle sweep. If I wasn't working from home, and we weren't on lockdown I'd give you the loan of mine.
