If implemented well with a decent power-supply, it will outperform even the biggest name pre-amps (we HAVE tried).

It's also used in the Apogee Duet, but here the lack of decent power supplies, the inferior clocking and budget convertor chip limit its performance.

Compared to the John Hardy M-1, by many regarded as the world's best pre-amp, it was like pulling earplugs out of your ears. The difference was never so clear. The spatial dimensions of the sound were much more vibrent.

Learn what the pro's (Meitner et al.) think of this chip:
ProSound News-Sound Related Articles I quote:"the designers at places like TI and Analog Devices really know what they're doing, and very often their $5 chips can give much better results than an elaborate, organically-grown discrete design. But wait, what am I saying? May the Lord forgive me... In the mean time, take a walk around the PGA2500 (TI again) if you haven't already. It puts a lot of well-respected discrete mic pre front-ends in the shade. On the other hand, I remain unconvinced by the latest line driver/receiver offerings; for some reason, their dynamic performance still falls short of a decent discrete solution"

1. Buy PGA2500 EVM $100
2. Buy a case $10
3. Power supply $20
