It's the kind of intrinsic detail I've always ached for, no expectation bias since I wasn't expecting jack from them, lol.
No op-amp sounds perfect, unless you've been persuaded into reading specs, essays and dScopes, and delusionary thereafter. Music isn't supposed to sound flat and neutral, OPA1611 with a STAX SR-009 and crystal cables is a joke...
"huh... I take it on and off... it sounds like... nothing!! It's invisible!! I can't hear any difference between this and... fresh air!!...... now all I need is a cloaking device and I won't even see it! ><"
Music is supposed to sound hyper-extended, hyper-detailed, with more distinct layering, closer intimacy at different frequencies, revealing in secret nuances within the music, with an intact, uplifting and unnatural tonal colour.
A karaoke room isn't "reference / flat" sound, it enhances the singers voice (just like studios), recording uses all kinds of microphones with tailored FR, to 'zoom in' on the right content. Technology and spikes in your transducers will zoom in further for heightened perceptivity and impact.
As such, op-amps are all different flavours of soft-drink (except OPA627 which is tears in a vanilla milkshake), it's just most of them taste like Diet-Coke from a tin can, AD797 like Tonic Water, and LT1363 like Coke from a glass with ice and lemon.
