Last beep from me!??
It took some long long time, but i found an answer for my search (and question)!
The Esoteric (P-70 and D-70) units had some very attractive characters, but failed at one specific factor (atleast when used without dedicated pre amp). That was the sonic character, which i found lacking in "flesh and blood". I bought the KPS 25sc and now drive this in CAST mode together with my FPB 600c.
I have never heard such a rewarding combination.
Oki, some systems may have an even higher resolution (they are few and absurdely expensive) or some may want a more romantic view/ colour (to describe sound/ sonic character.) But for natural lifelike reproduction of recorded material. This combo is superb no matter musical preferences and it truely excel at one of the most important factors of all....(which is..?)
The overall cheer excitement and sense of drama, dynamical contrast. To feel the power in every tiny cell. It's like an open window to the emotions the music expresses.
This combo does IT and proves to me what HighFi really is and why i am here.
And more, that it does not need to be of the absolutelly newest or latest model. Quite often we are too fast to always look at latest dac/ decoder, model or brand.
I can see the manufacturers and dealers liking it anyway!
But fellow friends, think twice.
Recommendable before many many other expensive gears.
I also have a special CAST cable which is better than any XLR/ balanced cable i've heard (again in this system).
This all silver CAST cable is rather cheap, but still very exclusive, anyone interested may ask me for a link.
Thanks and to all of You, good luck in Your quest for HighFi Nirvana.
