Testing was done on Soundmagic HE400i headphones, carefully EQ'd to be roughly linear. I used an HRT Music Streamer Soundmagic II for this test. Tubes: 6JI tubes (one of which burned out after 56 hours): Stiff, dry and congested in the centre-mids, and ran hot in the upper-mids/lower treble...

I was fiddling with the gain setting on my Little Dot I+, and it occurred to me that the op-amp was running pretty warm, perhaps warmer than typical for solid states, and that I'd seen people running metal op-amps with heatsinks. I had a plastic-shelled op-amp, which isn't conducive to heat...
