Tucked away at the end of a corridor on the Hilton's ground floor, the Estelon Model X Diamond speakers ($64,000/pair) were being driven by Concert Fidelity's new ZL-120V2 Special Edition monoblocks ($34,000/pair) via Fono Acustica cables. Preamp was the Concert Fidelity CF-090LSX2 tube hybrid line stage ($24,000) with the SPA-4C solid-state MC phono preamp ($14,000), and sources were an Esoteric SDACD player feeding the Concert Fidelity DAC-040 tubed D/A processor and a modified Denon DP-3000 direct-drive turntable. Considering the system costs, the sound from CD was a little disappointing—a fine vocal presence upset by uneven low frequencies, which I put down to room acoustic problems—but to my surprise the sound from LP was considerably better focused, with more controlled lows.
