I’m loving my experience so far, considering updating the V6 OPAmps to V7. Waiting for some reviews to hit the market.

I see how Colour and Texture is a full 10/10 in the v7 classic chart and I’m worried the Mids might get muddy.

I took quick Iphone picks but if you want pro pics, let me know,
Is there a serial [removed] to register the 3 year warranty?

Thank you.

The System

Listening with

Audeze LCD-2 Classic · Headphones: open-back, planar magnetic, circumaural

Impedance: 70 Ω
Sensitivity: 101 dB/1mW (at Drum Reference Point) ≈ 112.5 dB/V (calc.)
Frequency response: 10 Hz – 50 kHz
Plugs / cables supplied: 4-pin XLR cable; 4-pin XLR to 6.35 mm adapter cable; 6.35 to 3.5 mm adapter
Other: recommended power >250 mW;

Matching notes: At 70 Ω and 101 dB/mW, the LCD-2 Classic is a low-impedance load, and an efficient one: about 0.75 V (7.9 mW, 11 mA) for 110 dB SPL (calc.). Burson does not publish a 70 Ω rating for the Conductor 3X Reference. Its 32 Ω and 100 Ω ratings (5 W XLR / 2.5 W SE; 1.75 W XLR / 0.88 W SE) fall either side of it. The Conductor 3X Reference’s 0.5 Ω headphone output impedance is 1/140 of the load. ^{[1] [2] [3] [4]}
