  1. 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.
  2. 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 ??
  3. 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.
  4. 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:
  5. 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
  6. Might want to check your pictures. They show a pair of Behringer A500's. Not Sampson amplifiers.
  7. Nothing new to learn in the world of acoustics then. Sorry for wasting everyone's time.
  8. 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
  9. 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.
  10. 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.
  11. ME1500 to the bass drivers and Pass Labs to the rest??
  12. 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
  13. 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.
  14. I admit I wasn't listening for gain either. I was just floored by how good the Telefunken diamond 7DJ8's sounded when I put them in.......
  15. Oh, OK. So it's a bit higher! But the 7V might still be a tad lower in gain than a 6V??
  16. Bingo 2.9ohms. Ouch. Efficiency looks reasonable at 90db @ 2.83V
  17. And I just remembered, those figures on the BHK gain are based on the NOS 12AU7 tubes. If you are using 6V variants then you might get less gain and if you set the preamp to 6V and use 7DJ8 tubes you might even get another drop in gain.
  18. Are you here to help Chris or just prove me wrong?
  19. A DAT's speaker measurement device could run a sweep of your speaker's impedance in a few minutes and you'd know for sure
  20. Another thought is, if you have another preamp laying around with a known amount of gain, add it into the system. Set it to max' gain then increase the gain on BHK. If you are able to get the desired amount of SPL out of the speakers then you're looking at a system gain issue.
  21. Really? https://www.stereophile.com/content/holoaudio-spring-kitsuné-tuned-edition-level-3-da-processor-measurements https://www.stereophile.com/content/primare-cd32-cd-player-measurements https://www.stereophile.com/content/naim-nd5-xs-2-media-player-measurements
  22. Your issue probably isn't your amp not having enough power. Your issue is nett gain in your system. The BHK only has 9.3dB of gain if you use both balanced inputs and outputs. If you use either unbalanced input or output then that drops to about 3.7dB. f you are using unbalanced outputs from your DirectStream DAC then you're only getting 1.44V RMS. Not sure what the output of your Phono stage is and what the sensitivity of your phono preamp is. The Pass Labs has a 26dB gain which is not high, not low. So if you're using unbalanced in your chain and you're only starting out with a low vol
