  1. I first read the title as ‘Turning Fuses’ and thought this might be some kind of tweak where you’re supposed to rotate your fuses every few months to clean the contacts. Might give it a try. Anyone with me? Expecting all kind of night and day veil lifting.
  2. Looking at this I think EQ would really help you. If you need a unit to achieve this, the RME Adi-2 DAC has 5 EQ filter bands per channel which would probably be more than enough to address the problems you’re seeing. Experimenting with moving the speakers and/or seating position forward or backward could help with smoothing out the cancellation between ~150 and 400Hz and EQ will help tame the peaks below 100Hz - in particular that one at 45Hz will really be muddying the bass. I wouldn’t use EQ on anything higher than 150Hz max, and it should only be used to cut peaks - attempting to use boosts to get rid of cancellations is futile as it just cancels more! Could you post separate plots for left and right speaker?
  3. I’m also intrigued about your experience with EQ, as operating in the digital domain, this shouldn’t have degraded the sound and should be a great way to integrate your current speakers into your room. How did you feel it was degraded? If you love your B&Ws and ideally want them to work for you in your new room, I think EQ would be a great way to achieve it - happy to help if I can with this. Another thought - what are your B&Ws sitting on? Boomy bass from a suspended floor can be tamed using heavy concrete or stone paving slabs under the speakers. If on the other hand you really just fancy a change of speakers and your problems with bass are another reason to do this, then agree sealed box ATCs could be a good place to start, but I think in your room you might have bass problems with any floorstanders you try. Prior to EQ I had all kinds of booming with tiny Proac 1SC standmounters as there was a room mode at 60hz that they loved to excite. Could you post some of your measurements from REW?
  4. This isn’t correct, see my post above. I will try to find the online test and post it so everyone can have a go.
  5. I can hear a clear difference between 128Kbps and CD quality. There’s an online test you can do, I forget where, which allows you to do blind tests between samples of songs at different bitrates, 128, 320 and CD quality. I picked the 128 one out every time. This was a while back before I upgraded to a far higher resolving system.
  6. This topic is well covered in the RME manual, as Keith states, and on the RME forum. The ADI-2 DAC’s designers are quite clear that there is no way a different power supply could make an audible improvement to sound quality. https://forum.rme-audio.de/viewtopic.php?id=27006
  7. Right now I am of the opinion that the same digital file converted by the same (good) DAC sounds the same, irrespective of what plays it. This is after I swore blind that I could hear the difference between two streamers, and that Audirvana sounded better than iTunes. I now think this is because someone somewhere on the internet told me they sounded different. Since using the RME bit test and finding that iTunes/Apple Music is in fact just as bitperfect as Audirvana, they now sound the same to me. Expectation bias, I have learned to my cost, is a powerful thing. I don’t want to tell you you didn’t hear something, but I wonder if this is a possibility: in expecting the WAVs to sound better, you actually subjectively perceived them to sound worse because of the disappointment of them objectively sounding the same. Before investing in an expensive streamer, I would try some blind tests between the two sources, check that your CD rips are bitperfect, and check that how you’re connecting your SBT to the DAC is also bitperfect. Hope that helps.
  8. You reminded me of this review. I’m now very wary of anything I read in hifi magazines, but if you go in with the mindset that this reviewer neither hears differences between USB cables, nor believes differences are possible - but has to write something anyway because their boss has told them to - it makes for quite an entertaining read: https://www.whathifi.com/audioquest/cinnamon-usb/review
  9. Many thanks to everyone who has replied to this thread. The links to papers and monitor positioning guides were informative - thanks. Thanks too for the YouTube link, though I have to say I’m often as wary of YouTubers as I am of magazine reviews. I can take people seriously who make exceptionally well-designed audio equipment. However PS Audio makes kit that often measures badly and McGowan claims USB cables make a difference to sound quality. On the other hand RME makes kit that sounds and measures superbly and is used by pros all over the world and their engineers (who don’t have YouTube channels) without exception say it is ridiculous to suggest USB cables impact on sound quality (which aligns with my experience). So I am wary of McGowan‘s advice. It seems there isn’t a consensus on whether corner positioning (with appropriate EQ and treatment) will be a disaster sonically. Though there does seem to be a consensus that only experimentation with my room and system will prove conclusive. So that’s what I’m going to do - and I will report back with my findings soon! Thanks again to all who replied. James
  10. I think there are many reasons that people come to a hifi forum. But I think most people here came here because of a love of music and a desire to invest time in reproducing it in the best way possible for the least cash possible. There are millions of possible component combinations, so I’m in favour of anything that can help me identify high quality components without having to listen to millions of them. And if I can filter out snake oil products by removing the expectation bias that snake oil sellers feed off, great. Believe me I’ve fallen for quite a few of these in the past! Though not the final answer, measurements and blind tests are two very powerful tools in achieving this goal. So, for me at least, I think they’re valid in any discussion of hifi components. J
  11. Have a large glass of wine and try again?
  12. The ‘uh oh’ was in dread of another twenty page cable debate marathon. I am of the view that cables make little or no difference to sound, so long as they’re well made, and that EQ such as Dirac makes huge improvements to sound, so long as the system is carefully set up and measured. In short I disagree with you, but I am happy to leave it at that, not derail the thread further and let the OP decide on which avenue they’d prefer to take.
  13. Thanks @speedskater. Why do corners affect stereo imaging? Does this mean Audio Note speakers don't image well?
  14. Hi all, I’m currently reconfiguring my listening room - apparently also known as the ‘sitting room‘ by other members of the household. SO stipulation means the speakers (ATC SCM20s) will have to go hard against the front wall, with me sitting on a sofa against the rear wall. Not ideal, but hifi isn’t everything (I’m told). I’ve been using REW room simulator as a guide and it’s suggesting putting the speakers in the room corners will give the response with fewest deep bass nulls. Clearly Room Sim is an imperfect model and only listening and measurements will identify best positioning in my room, but EQable bass peaks aside, are there any disadvantages to corner placement? Audio Note and sub manufacturers seem to recommend putting them there. Would early reflections of higher frequencies be a problem? And could these be dealt with using acoustic panels? Many thanks, James
