 The simplest possible home setup would be a CD player/dac (one output amplifier ) > power amplifier > speakers. 2 amps total. Most usually, there will be a preamp in between - either as a standalone unit or as a part of the integrated amplifier. 3 amps total. EACH of those amps can be regarded as cascaded input and output section - thus bringing the sum to four or six. Where are tone controls, equalizers, active filters, .... - you do use equalizer to get the speakers or...
Studio R2R decks. All of which predate amorphous heads by more than enough. But I admit, did not know Teac made consumer R2R deck with amorphous heads. That should be interesting. My dream R2R deck would be Technics 1500 or 1700 mechanics (wow and flutter better than anything else ) with amorphous heads and up to date electronics.
What @stv014 did is great. But you will never get the whole quality of the DSD file is capable of by converting it to PCM - it is a lossy process.  Then again, if you at least keep the PCM at least at 88.2 kHz sampling, DSD bounced to 88.2 will still sound better than CD Redbook.  Whether DSD or PCM, it is always better to stick to the original file played natively than using conversion.
That is WHY I do not like studios with their spiky and iffy electronics. Which is a direct consequence of the "above 20 kHz does not matter"- adopted also in studio equipment. And that is why I prefer audiophile gear that is usually MUCH better designed than studio gear. The studio gear that is OK is usually beyond the reach of almost anybody. Starting with microphone preamps... I agree there is no such thing as too low noise floor - it always comes handy.
Say six amplifiers in series, each flat to say 0.2 dB @20 kHz will not end up being at the output of the sixth amp at 0.2 dB, but worse, around - 1 dB; it would also have greater phase shifr, etc. If the amps have MHz bandwidths, than this is of no consequence for audio - and that is why I prefer them. "Amplifier" is not only a box with input and output jacks; within such a box, more actual amplifiers in series can be employed, so figure of six is a VERY optimistic for the...
Great post ! Just an update to current technology - there is a microphone capable of 100 kHz response (Sanken C100K), there is a recorder capable of recording it ( Merging Technology Horus and Hapi in DSD256 mode; exact response is not known (yet), but it certainly could reach 100 kHz @ - 3 dB if not better and a gentle roloff above, no brick filtering as required by PCM  ).  One has to ENSURE there is no low pass filtering "somewhere". In my cassette day recording, I made...
In case of debates on head fi, "single factor" that bothers me is say frequency response, THD, IMD, S/N, bitrate, sampling frequency - you name it - used in isolation as being the influential factor for determining the SQ - and that there is a limit beyond which it no longer makes sense to improve it further. Maybe so - in a SINGLE device. Any usable system consists of many links in a chain - and their defects add up. Enough of them in a series each having an error below...
There was nothing else that could support the voltage required back in 1986 but HSD ( Hollow State Devices ). I read there are some Panasonic crazy voltage SS devices either in development or already commercially available . When I heard how much they are supposed to cost, it is back to lack of air. 
It is pretty much exactly as you have observed. It was not a modification of any commercially available product, it was the fruit of experience gained in building DIY ESL amps by Heymeyer and Sanders ( published originally in the Audio Amateur, reprinted by The Speaker Builder ) and a design by the developer (whose name I keep forgetting, but respect very much )  of otherwise much more known RKV Audio Valve amps, published as DIY  in the mid 80s in Germany. And then went...
Analogsurviver the designer does not please the ears of analogsurviver the listener, then analogsurviver the designer tries each and every possible way to amelioratethe situation, with analogsurviver the listener appreciating the efforts but commenting "better but not quite there yet", which has a consequence of analogsurviver the designer scratching his head even more and coming up with a yet better solution - and so forth for about two years. Until analogsurviver the...
