Hi
I have ATC SCM 20ASL speakers which are extremely revealing and I use them with my JL Audio dual F112v2 subs through a JL Audio CR1 crossover.
First I had a Naim Nova which sounded very good, and I listen to probably 80% rock from mainly the 70's and 80's but also love stuff like Kraftwerk to Yellowman and just recently started getting into Classical.
Naim has a great in-house sound (PRAT) signature especially for rock, but I knew I could do better, like you the Bartok piqued my interest, so I arranged a home demo, sounded great and decent incremental improvement over the Naim, but in my opinion for two and a half times the price of the Nova it was not a real contender, then luckily one day on one of my frequent visits to my local dealer I got a deal I could not refuse on a rather special Streamer/Dac/Pre-amp, and for not a great deal more than the Bartok.
Said Streamer/Dac/Pre-amp promptly taken home for a demo, quickly hooked up in my system, and I knew absolutely straight away I had something special, just everything I had been searching for in so long.
Product being the T+A SDV 3100 HV, at the same time I bought a Sablon Audio RJ45 ethernet cable which for the price as to be one of the best purchases I have made, everything just fell into place, next and last on my list to buy is the EtherRegen.
Hope this helps.
Good luck and hope you find audio nirvana like I did after a long and sometimes frustrating time.
