  1. I had the exact same problem. A horrible hum from one sub. I fixed it by plugging the sub into my Hi Fi circuit rather than the separate one and moving the sub closer to the processor. The problem is I try to keep all SMPS's off the Hi Fi circuit so it really defeats the purpose of having separate circuits. I get the impression that a really long run of unbalanced cable will be more prone to hum than balanced. I had a 10m run.
  2. Can you use a balanced connection?
  3. I'll taken it if you can post it. Happy to pay the postage. Cheers Andrew
  4. My feeling is it all depends. The same master at 16 v 24 bit will sound the same. Often a 24 bit release will be be a new remaster and consequently sound different.
  5. Yes, I think that is true but when doing comparisons between a 16 bit file and 24 bit file (of the same song) I do notice a 5% or so difference in clarity. It sounds slightly clearer, especially with vocals. Have you ever noticed any difference at all? If you notice a 5% difference, which is a significant amount, then I would suggest you are listening to different masters. Mid-range “clarity” is not something that will change with bit depth change.
  6. No. I agree completely with @davewantsmoore post above.
  7. I have attempted to do this in a semi-formal way. The biggest problem is many/most MQA files on Tidal are different masters from those available as 24 bit downloads. It’s almost impossible to do a true comparison. Personally I like the sound of MQA just as much as uncompressed files but MQA comes with a lot of baggage that I’m not willing to accept.
  8. Cheers @jjday Yes I absolutely loved this AVR. Only sold it to get a Denon AVC-A1 HD, which really is not that far ahead of the Onkyo.
  9. I've imported used gear from Japan and never had a problem with EMS. I did however have a problem with a TT that was sent internally in Japan and was wrecked. Luckily Easyauction Japan noticed the damage before sending it on to me, returned the TT and refunded me in total. Bear in mind the packaging is the critical factor. All couriers are probably tarred with the same brush. If your TT is in the original packaging it should be fine, especially with insurance. (for what that's worth!) These TTs are shipped around the world all the time by the manufacturers and distributors. Saying that they are probably shipped in bulk on pallets. Check out https://www.easyauctionjapan.com/search.php?key=technics sl 1500&new=1&typeofshop=0&signenglish=&jte=&language=en You might find a bargain and you'll be looked after well if this is what you're looking at. Looking at those listings I now realise they are for OLD SL 1500s so that's misleading. Maybe you could ask for advice from the retailer.
  10. No I can't say I have. XLD will take a long time to rip if there is a problem with the CD. My guess is it is checking with AccurateRip and when it can't find a match it tries again.
  11. Yes XLD is my favourite. iTunes will just eject the disc if it can't rip. XLD will keep trying depending on your Preference settings.
  12. Seeing no one has answered I'll chime in. For what it's worth I have a Nak (forget the model but not up to the 505 standard) just sitting here in the same condition. Mine lights up and makes whirring noises as well. I pulled it apart and had a look but it looks too hard to replace the belts (even though I bought some on eBay) so I gave up.
  13. Of course. That's what happens when I rush and read too quickly in between work emails. At least I can infer from your post that the loading resistor is in parallel, or have I misinterpreted that concept up as well? OK, back to the two head-amp options then.
  14. Thanks. Yes. I remember that concept from my high school physics 45 years ago. Certainly if the loading resistance is in series with the input this would be correct. What I can't understand is when I set the phono to 10 Ohm loading the volume is MUCH lower than 300 Ohm loading. This would indicate to me the loading resistance is in parallel rather than series. If it was in series, increasing the resistance by adding 300 Ohm in series should make the volume louder but that doesn't make sense to me. Maybe I need a circuit diagram but I can't seem to find one on the web.
  15. Yes. Normally. I can remember a little about electricity from high school but not much or how it relates to the concept of cartridge loading. Reading the posts above I get the impression the cartridge loading (number) resistor is in parallel with the input, not in series. So when I have my phono stage set at 300 Ohm loading the 300 Ohm is in parallel with the input wiring. Is this incorrect? If my understanding is correct then adding a resistor in series will decrease the loading value (and the signal level). Certainly when I set my phono to 10 Ohms loading rather than 300 Ohms the volume level is severely reduced, which is counter-intuitive if the resistor is in series. One troubling thought is "loading" sounds like it is adding resistance (as in series), rather than sharing resistance (as in parallel). To quote @andyr, I have drawn a couple of crude diagrams to get this right in my head. Maybe I'm totally wrong though. Is this how 300 Ohm loading works? Will this make 600 Ohm loading?
