RE: Purifi Based Amps

@MarcL,

All of the boutique opamp input buffer versions that ASR has measured to date have measured less clean than Purifi's EVAL1 input buffer.

The EVAL1 measures 3dB better without pre-gain than with pre-gain so if any improvements are to be had, would be have pregain without the 3dB loss in SINAD. So far, I haven't seen anyone achieve that.

These boutique opamps appear to be expensive tone controls (which can be done elsewhere).

VTV just posted a tube based input buffer version for a significant price increase (+ $1,250). I understand they are a tube company, but don't see the value add other than marketing.

The only possible "value add" that I have seen is a micro-controller version from Vera Audio that allows bridging of both the NC500 and Purifi modules but they aren't cheap.
