I 'bought' that same model Pre ... Used.. from a local dealer.
Albeit Years ago... when these were Current production items.
Took it home where it worked.. Reasonably well.. for about an Hour.
Then it Didn't.
Promptly returned it next AM and dealer wasn't surprised, saying that these are Unreliable contraptions .. truth be told.
And that they would not repair it, as repairs were uncertain and the cost far exceeded the things' Value.
Caveat Emptor

About the reliability of NAD1000: I have it already for an year, the device is probably +-30 years old but I have never had any problem. It works well and sounds well. I am not that good in the electronics but what I see from the scheme it seems quite simple and I do not see any very expensive parts. May be the dealer has estimated the work for the repair very high....
I tried Arta. Here I put some results. May be I do not do everything right. Please check:
The generator is adjusted on white noise: -20 db level, Inp: left, Fs(Hz) =48000, FFT=4096, wind: Hanging,
The signal goes out from the laptop to the input of NAD 1000, treble and bass are on 0.
The first graph is with volume on 50 %, the second graph with volume on 100%. I see some difference in the highs :

Any update on this (Nasich) issue ?
Just asking because I got my hands on a 1000 and going to implement the "upgrades" listed in this thread and I'm curious about this treble issue.

Hi RS232. All the upgrades discussed here made improvements to my preamp. The treble issue in my case was combination of not good interconnect cables, speaker cables and the main reason was some acoustic problems of the room. Now everything is solved and actually I do not use any more preamp. The DAC is connected directly to the power amp and everything is OK.I do not need any nore treble correction up. I went even to a doctor, fortunately my hearing is very well for my age. If you have any questions I am available.
Good to hear that your ears are fine and that you solved the issue with the treble on your system.
My questions already have the answers I need and on top of that I have the SM for the 1000 and the 1000S
Just the relay is in drought I have a load of 4.5V micro relays with Silver finger with Gold contacts only need to figure out how to drive it.
Regards

And so it begins...
Got power supply recapped with Panasonic cap (tried to keep original values where possible)
Moving to the Phono preamp and have a question:
Have all values in Panasonic and Rubycon Muse caps apart from the 2200ufx6.3V and my question is, how critical is this cap in the circuit ?
(My preamp is the 1000 and that cap is actually only 1000ufx6.3V the 2200uf is from the 1000S service manual)
