It sure would be nice if it were just about the numbers.
Hi Danny,
They are a strong indicator if we are talking about purity of signal retention (straight copper) versus additive colorations (listening to equipment signatures).
Transducers are the weakest link in today's audio chain.
I think you have some hands on experience with the newish Purifi drivers, but don't know what your thoughts are on them.
They appear to have some quality at a steep price and boast low distortion.
Here is a blurb from one of their staffers.
"... The PTT6.5X is at -80dB (1Amp peak, 1kHz), the new PTT8 is at -90dB and we have prototyped a 6.5 with -100dB. ..."
Their best transducers (including latest prototypes) fall short of the the rest of the contemporary upstream audio components in a signal chain. Nowhere near -[240-300]dB or even 130dB.
I would appreciate your honest feedback on all 128-bit and 64-bit up to your favorite DAC, but it would require multi-channels of your favorite DAC to do so.
Most canned consumer hardware (e.g. DEQX, miniDSP, etc.) do not do this precision of math and are tap limited, thus are not representative of current potential.
