Here's my current system for k1000 (which I believe it can push out real k1000 in acoustic signature)
Source: Linn Genki (modified as best as possible with blackgate caps, superclock v3, separated phyton ultra low-noise terloids opa627au, transport damping, aes/btu out, etc.) <- Virtual Dynamics Nite II
Digital Interconnect: Nordost Valhalla AES/BTU
DAC/Pre: Grace m902 (modified as best as possible with blackgate caps, superclock v3, opa627BP+ad8620, Nordost Valkyrja wiring, xlr balanced out, separated terloids, etc.) <- Nordost Valhalla
Analog Interconnect: Nordost Valkyrja XLR
Power: Firstwatt F1 (Most recent Nelson upgrade) <- PAD Anniversary
Recable: Apuresound V3
Output: k1000
Accessories: Wattgate silver outlet with Pure Sine 1000 (Prototype product from Clef audio with full upgrades)
It sounds so real for both bass and treble. So real but yet not too intense for me. I wouldn't wish for anything else beyond this
P.S. Icarium, have you ever tried k1000+recable with SDS in balanced system? I'd like to hear your impressions
