Accuphase DC37, Burson Soloist 3X GT

I have a Conductor V2. It works well and sounds nice. I am happy with it.

The System

Listening with

Abyss AB-1266 Phi TC · Headphones: open-back, planar magnetic, circumaural

Impedance: 50 Ω
Sensitivity: 88 dB/mW ≈ 101.0 dB/V (calc.)
Frequency response: 5 Hz – 45 kHz
Plugs / cables supplied: 2.5 m 4-pin XLR cable with 6.3 mm adaptor (JPS Labs); other terminations optional

Matching notes: At 50 Ω and 88 dB/mW, the AB-1266 Phi TC is a low-impedance load, and a fairly demanding one: about 2.8 V (158 mW, 56 mA) for 110 dB SPL (calc.). Burson does not publish a 50 Ω rating for the Soloist 3X GT. Its 32 Ω and 100 Ω ratings (8 W XLR / 4 W SE; 3.8 W XLR / 1.9 W SE) fall either side of it. The Soloist 3X GT’s 0.5 Ω headphone output impedance is 1/100 of the load. ^{[1] [2] [3]}
