Hi Peter, Just a small teasing with your future speakers. You wrote: When things sound bad/wrong etc. etc., the very first thing "we" learned is : it will be the room. It is our very first huge excuse. ---------------- You will see the efforts you and BertD have to manage to get the right sound from your speakers in your room. And one request: Please do not shut down your server during the first extended listening sessions with the new horns. Joachim

I will just note here, so not to offend anyone any more than necessary, that I'm 100% on Peter's side. He is not the "only" one that thinks that way, we may dispute who was first or the best ways to get the "good stuff", but that's another ball game ... One way of looking at it, is that the sound when it emerges from the speaker drivers has to be "right". If it's not, then you need to start playing games with room acoustics, etc, etc, etc, to "improve" things ... Frank Hi Frank and Peter, let us answer the question of the original source of the music! The music is recorded in a studio or opera etc. A picture of a new concert hall in Copenhagen see: http://admin.medite-europe.com/imagebank/59.jpgThe sound in the studio or concert hall must sound right at first, and then the sound engineers are mixing the record in their studio, and in their studio the sound must be right too. We hear the result of the recording engineers at our speaker drivers via our frontend. Let us assume our listening room is ultra modern and all walls around are glas walls, no curtains around. Then I promise ............... . Another link: http://www.acoustics.salford.ac.uk/acoustics_info/studio_design/Joachim

The only other thing which might explain it is that I have spent months building and carefully installing, through trial and error, bass traps/absorption panels at reflection points (walls and ceiling--floor has heavy wall to wall carpet) and diffusors in my man-cave listening room on the 3rd floor.
Hi Boleary, Room treatment is related to acoustics. A simple definition is "acoustics deals with what sound does in a room" (see "Acoustic Design For Home Studios" by Mitch Gallagher, chapter 1) The room treatment is the physical basis (controlling reflections and reverberation, bass traps etc) for a superb sound. Joachim Well, everybody may think about this as he likes, may find whatever "scientific" papers he likes ... if you only know that I totally disagree. It would be the very first thing to DESTROY your measure on how your system behaves. I won't say that treating the room isn't good to get sound to perfection, but I do say that it is the most wrong thing to do to judge your system for behavior in the base. Although I must have said it a 100 times, you may have missed that it is my sheer measure to get rid of any single standing wave (low frequency *and* high frequency) up to any most difficult corner in the room. And so I don't use any room treatment, rather have curtains open than closed, and no XXHighEnd or driver or whatever will go out when I suddenly perceive *any* anomaly regarding this. The basis of our hobby is physics and there are tons of literature available how to built the perfect room (Opera houses, studios etc.) for music performances and replay. Please see the two links only. https://ccrma.stanford.edu/courses/318/mini-courses/papers/rooms/Gade%20-%20Handbook%20Ch9.pdfhttp://downloads.bbc.co.uk/rd/pubs/archive/pdffiles/architectural-acoustics/bbc_guideacousticpractice.pdfThe XXH software is creating the BEST SQ in your room only, and no other room will be on par with your SQ! You are measuring and adjusting the software to avoid your room abnormals. (cause and effect) Everything counts, even the material of the wallpaper. So, my standing waves are different to yours due to the different room sizes and material of the walls etc. Individual room treatment is mandatory for an excellent SQ. In other words, a very expensive chain will have a nasty SQ in an untreated room, and a small budget chain will have a superior SQ in an optimal treated room. This is my experience over the last 25 years, even with XXH. A link to handle abnormal room echoes/reflections via software. http://www.lyngdorf.com/technologies/roomperfect. Joachim

Ahhhh, it makes me want to give up on computer audio altogether. I'm half serious too. But the guys who like W8 in Normal OS are right - the sound is way more relaxed and listenable than in Min OS. I also just compared W7 (with my old settings, which I was quite happy with) to W8 and I prefer W8 in Normal OS. The latter seems at least as detailed as W7, but more natural and less annoying. So is the conclusion that stripping an OS down to a bare minimum is detrimental to SQ (because noise is not as well randomized)? Mani. Hi Mani, the conclusion with the experience of all participants of this thread is, Peter has to program/modify an OS destined for XXH only to get a consisted basis for future (next 10 years)upgrades. Joachim P.S. I will not give up Computer Audio since W7 is supported until 2020, but I have to buy a new Audio PC soonest.

Had to go back to W7 due to the “small ball like soundstage” in the center (mono effect) and missing 3D room image. Now the soundstage and the resinous sound of the violin are back. (my listing SPL is well below 80dBA)
The abnormal SQ differences between W8 and W7 could be PC (built in 2010) related. Under W8 with the "W7 Shell" installed, the boot manager was not working and an access to the BIOS was not possible anymore (on my PC).

Hi Peter - I have tried different Q readings from around 10 to 20 but I still get the random stopping. I will try higher SFS say 20 to 30 but that is no good for me long term as it really does negatively impact SQ - SFS2 is where the magic SQ happens. But of course it will be useful to know if bigger SFS settings does indeed prevent the "stopping" problem.
Paul
I had the similar problem with W7. Sound is gone, the slider of the time scale is still moving. Pressed the "Stop" and "Play" button again and it works until ........... . I do believe that this behavoir is related to the tweaks. Joachim
