Merlin,
let me put some figures together...
Speakers
2 pairs of Nestorovic satellites 21400$
1 pair subwoofer 12000$ (this is what I heard today, I am not sure because I thought I bought them much cheeper..)
Amplification
Second hand Sonic frontiers preamplifier modified about 4000$
Second hand Nestorovic NA1 Tube amplifiers. If found they may cost about 8000$ (?) per pair.
Krell PB300C, listed in CH for ca. 9000£
(got a demo model for about 50%)
Cables
All cables are Fadel Coherence line except for the special made Goldline speaker cables. Listing about 20000 £ (got for much less)
Digital
Metronome CD-Transporter Kalista and Converter with Venture Digital XLR cable. Listed in CH for about 19000£ (got it also for a very special price)
Analogue
AAS Turntable with Mozart arm and Jan Allaerts MC2 Finish cartridge. Listed for about 14000£. The TT I swapped it for the second hand system 16 I bought years before.
Klyne Phono section (type 7): don't know how much it costs in UK. I got it directly from Klyne.
The Walker model would cost 10500$.
A few considerations
For the system 16 you don't need a 300W power amplifier. Nestorovic recommends a 200W. There are certainly other types of amplifiers which would do good enough as my Krell and would cost cheaper. My choice was also done because I could get the Krell very cheap.
Fadel cables are fantastic but there are cheaper power cables which are also good enough. For IC I would still recommend the Coherence. To save a bit of money I would suggest the Coherence instead of the Goldline. When I bought the Goldline there weren't any coherence loudspeaker cables. For low ends why not the Reference One. That line is cheaper and certainly good enough for low ends. Cheaper cables from other companies would also be enough for low ends. Buying all cables from the Fadel's dealer gave me a good rebate.
Nestorovic products are very very difficult to get on the second hand market because nobody who has them would sell them.

Maybe if you are lucky you will be able to find a very old model but I wouldn't recommend to buy them. The loudspeakers seem to cost a fortune but believe me there are so many products on the market which cost much more than them, which aren't even half as good. But of course that is a personal opinion. The fact is that Nestorovic is not much known since he doesn't do any marketing. he says he has enough work for his small company and doesn't need more. With more orders the quality would drop. Talking to Nestorovic today I heard that he doesn't want to make any more subwoofers. First he hardly earns anything out of them and second the backs of his employees get quite ruined when making them (60-70Kg each). The prices of the satellites will go up at least 20% since the material for the new version and other costs raised considerably. For pop and electronic music I wouldn't buy nestorovic loudspeakers because there are other cheaper ones which give also very good results. This is my opinion if you are interested in the price / quality ratio.
For classical music many small quality difference make a big difference at the end, which is much mode audioble as for other genres.
Have I answered to all questions?
