For those of us who are not engineers (but only informed enthusiasts), would someone care to explain in relatively simple language why filterless DACs are better? I have been spending a few days trawling through the web and have come across some articles (written by Dan Lavry, Kusoniki etc.) but I can't understand them for the life of me. 

I also have a Weiss Dac 2 which is 24/192 but not filterless, which my wife thinks would be hard to beat, but I am keen on understanding the NOS1 better...

Thanks for the help.

Yes there is a solution to connect XXhighend to the ambiophonic dsp, even 'virtually' (called virtual cable) which I am using, but having native support is always better imo.

Also like you I believe in no sweet spot, but good staging (or at least something remotely similar to a real performance environment) is something impossible to achieve in a simple stereo environment (without signal processing).

We can keep wishing.

One day I hope that you will find time to integrate multi-channel support too!

Thanks for the audiolense link too.

Dear Peter, Hope you are well.

I continue to be impressed by the clarity and musicality of XXhighend. However I understand that there is one thing which bit-prefect replication cannot really address, and that is activity of the soundwaves in one's listening room (I am not sure if you have read Floyd Toole's book "Sound Reproduction: the Acoustics and Psychoacoustics of Loudspeakers and Rooms) and spatial effect.

Apart from repositioning the listener and speakers, some software solutions exist which process the audio signals to enhance or alter this effect. As an audiophile I inherently distrust signal processing but having auditioned the player, I have to say that I am very impressed by the depth of the staging and stereo image (especially of pianos and voices). In fact I would consider the slight degradation in quality caused by signal processing to be a valuable trade off if staging can be improved, but too much.

Which therefore leads me to my next question: Is it possible to incorporate DSP support for xxhighend, so that I can use the Audiophonic DSP to improve my stage but not lost too much fidelity?

Thanks for your input as ever.

No harm done Calibrator. I appreciate your posts.

Peter - thanks a lot for putting this feature in your to-do list. just wanted to take this opportunity to let you know that I am really loving your product. It whips foobar, itunes and even cplay. I know there a lot of skeptics out there who do not believe that one bit-perfect player is different from the next, but I have a pretty high grade system and every single person who has heard it (on my system) believes it to be better. I am not an engineer so I can't explain why that is but "the proof is in the pudding" - as they say. I think that engine #4 sounds better than #3 on my system but I have a firewire DAC, so the sound cuts out after a few seconds. I think that it's the same problem that USB users are finding with engine #4.

Looking forward to your next upgrade!

Thanks a lot guys! I really do appreciate the help and for the list of shortcuts.

one love to xxhighend and this forum.   

u r rite about that, audiodidakt.

another question if I may: is there a shortcut for toggling the library? I would love to be able to press a button and have the library page come up so that I can browse for albums. Right now I have to use my remote to control the mouse to make the cursor go to the library tab and select it. (which exerts too much energy on my finger - just kidding).

I did use the search function but all I got was a bunch of posts about Autohotkey when I typed in "keyboard command". same result for 'keyboard shortcuts' also.

anyway I have paid for my program so I feel entitled to ask reasonable questions here.

Audiodidakt I use usb-irt. it's a bit pricier but works fine for me.  Eventghost is solid, imo, and infinitely customisable. I can program my pc to boot up, launch xxhighend, turn on my amp and pre-amp, select the correct preamp input, turn on my tv (which is connected to the pc) and select the right av input on my pc by just pressing only one button on the remote. that's using a combination of USB-IRT, Logitech harmony, the infrared remote pc powersupply switch (from Simerec) and eventghost.

Hey guys! I am using a Logitech Harmony Remote with Eventghost to control XXhighend, and the only way I can do that is to map my remote buttons to keyboard presses, which works very well. On the XXhighend interface itself some commands are underlined so I've managed to identify them pretty easily. However there are some commands I am unable to find the keyboard shortcut for, such as the keyboard command for calling up the library. Does anyone have a complete list of keyboard commands for XXhighend by any chance??

Thanks ever so much
