Nothing is ignored
i bought
kef r3 because i have been adviced here that there will be night and day difference, between naim muso 2 and kef r3,
i also bought purifi based amp nad m33, because i was again told night and day difference between my 30 years old jvc,
i have not ignored any advice i cant buy anything in the world i dont have endless budget like most people here.
I will need now to change the speakers,
and all be sorted out .
i cant sale the amp in 2 years at least.
Firstly, there is the point that you've selected the advice you've taken. Not everyone was telling you to buy either. Some of us did question the "night and day" comments. For example, I warned that the "night and day" difference between the R3s and the Muso depended on proper placement of the speakers. And as I remember it, the R3s were recommended and you bought them before you told us this is a desktop setup.
You continued to use the JVC amp after several people here told you to wait for the M33. That wouldn't have got you out of the mess you have now, but it does raise the possibility, however small, that you damaged the R3s. I can't tell from this distance, obviously. For now let's assume otherwise.
And I also advised you to use the Muso in the meantime. That was deliberate, because we know you preferred the sound of the Muso. Sure enough, you sold it off cheap.
We advised you to look at manuals and so on before buying, so there is no excuse for you to complain about the on/off with the NAD, because it was there for you to find out all along.
Secondly, there are people on this forum (but not involved in your threads) that are using the R3s as desktop speakers successfully. So we know it's possible. You can extract yourself from this situation and get sound that should at least be equivalent to the Muso for your much higher expenditure, and hopefully still better.
I don't know how much of the setup suggestions you've tried - for example, I made some suggestions about placement, and also to try to set the speakers up without DIRAC or the sub in place first, and to get the best sound you could that way. That advice by the way is quite deliberately given. Things like DIRAC and subs will improve a decent sound but they won't magically make a lousy setup into a great sound. You aren't the only person who needs to learn that judging by some of the posts here.
Anyway, let's start from where you are now. The M33 is not, sonically, the problem here. We have to deal with the room, the desktop, the R3s and of course your reaction to what you have.
So, please do the following and report back.
Firstly, for now, switch off DIRAC and make sure any other settings on the amp are neutral or turned off, so you have the direct sound of the amp.
Secondly, disconnect the sub for now.
Thirdly, make sure you are using BluOS or your phone via Airplay, and not the computer output. By doing this, we can discount the computer output as part of the problem.
Fourthly, do the test I suggested earlier about putting the speakers at the very front of the desk and listening from a distance. If that sounds any better, then we may have a placement problem. Do that experiment with the foam plugs out. If the sound is still "horrible" then the placement issues may be less important here.
Fifthly, listen to the M33 output at a low volume with a pair of headphones. That should at least sound useable. If it sounds horrible with the headphones you may have some obscure input issue going on
Sixthly, listen to one of the R3s in mono - the one that is not in the corner. If that sounds a lot better, again we have some kind of placement problem. If it still sounds terrible, do the thing I suggested under that one speaker, standing it on a couple of paperback books, and try again. If that still sounds really bad to you, then the at least part of the problem is that you just don't like the R3s and at least part of the answer is to replace them.
Seventhly - and I would personally do this
before the first six, but it doesn't sound like you would - as I keep repeating, you must go to some hifi stores and get some demos of the systems and speakers they do have. You absolutely MUST do this before you spend another cent on anything.
When you've worked through the six steps, come back and report here. No videos this time - try to describe the sound in words. This isn't normal advice at ASR, but in this case we are dealing with your reaction to what you are hearing. We can't hear it as you do, and I don't trust videos.
Also, can you post the Dirac response some other way - I get access denied when I try to look at it.
