OK, my first two slightly more educated question.
1. I see that at its best your software will give out a 32bit/768Khz signal. Are all versions capable of this? If not can you give a a brief idea at which development points (software editions) step ups were made.
2. Does the computer one is using affect the ability to give out 32/768. If so, is there a way to see what one's current computer is achieving?
Thanks Chris

Yes Peter, I originally bought the Podium Sound speakers to experiment with Layered Sound at home - near field horns complimented by far field panels (played at just sufficient volume to underpin the main speakers). I could clearly hear the effect, but after a while became bored of it in the home environment (bit like what happened to me with 3D TV). So the speakers became a system in their own right and do a really nice job when fed a signal from the very 'precise' XXHighEnd. I am having a clear out of unwanted Hi Fi, so at some stage will need to decide Hedlund horns vs Podium Sound speakers. Not a decision to rush into.

Chris, seriously, nothing stupid about it. It is only that I can't have answers of 5000+ posts in one post. So I almost feel guilty. Just ask what you want to know. I mean, it also can not be that a random newbie is not going to get answers other than reading through a whole forum, right ?
Don't hesitate ... Peter
Thanks Peter. Please do not feel guilty. Your time is more valuable than mine so I will do some reading and get back to you.

I hear what you're saying Peter, but there were no questions in my early message., just a compliment.
I still have all the elements of both systems which eventually I will make into one and sell all the excess stuff, so the horns could re-enter the equation, but without the DSP etc
I am slowly getting to grips with this digital stuff. Simplistically, do I understand it correctly that XX HighEnd will always give out 192Hz and that any NOS DAC not capable of handling that will compromise the sound?

Chris,
What you feel there is current. Or maybe I could say : the "charge" the chassis received. Not good for SQ at all.
Unplug all your interlinks and other inter-device connections, have them powered on, and measure the voltage between the various chassis'.
Try to have the voltage (the potential difference) to be the least in all situations. Most often this is a case of twisting the plug 180 degrees - something we can do over here. You can do it too, but you must make your own plugs and sockets. Otherwise try all the combinations with - and without mains earth. Again something you can't do easily but this time it needs a modded (extension) socket only. Have a larger one, and cut the mains earth from half od the sockets. Now you can play around.
Regards and have fun (ahum), Peter
Thanks Peter, when you say twisting the plug 180 deg do you mean (for us in the UK) swapping live and neutral? Sound like a good job for a wet afternoon.

As you will see from my profile below I currently run two systems. The first evolved over many years and is very much a near field system almost like wearing giant headphones. It has all the characteristics associated with conventional Hi fi - drive, finesse, detail, low lows and high highs but it is also a DSP system . My front end was once a Counterpoint CDP and Linn Sondek/Ittok, but on discovering XXHighend they were both replaced in favour of the Computer. This system has given me a lot of pleasure and certainly impressed others who came to listen. My second system is very much a far field system, and follows more closely Peter's philosophy, employing a NOSDAC. The NOSDAC and amp cost less than £400 for the pair and the speakers which are no longer available were a real find. Here is my discovery. As Peter has evolved his software and philosophy I would rather play and enjoy the second system

Some bits of Hi Fi kit, once plugged in the mains, have a tiny vibration/hum in the casing. It's not transformers vibrating but it almost seems as if the casing is 'alive' particularly when touched very softly with the hand.
I'm sure its not a safety issue as this occurs on new kit.
What's occurring here and is there an impact on sound quality?

Thanks guys for the prompt responses. I have read that different batteries 'sound' different, and there are other rechargeable alternatives including Ni Cad and lithium phosphate. Would these be a better choice? Scientifically its an interesting finding that a lead acid battery sounds noisy, as its just a chemical reaction, but I guess it might be the ever changing formation of hydrogen bubbles on the plates that causes variability. Peter, I like the IR temp sensor idea - its another toy to play with Coen, if you wouldn't mind I would like the name of that 12 volt linear supply as a fall back measure.
