I am sure many here are quite happy with their DSP reverbs, and software VST convolution apps, but trust me, even an analog I/O PCM70 @ 20 bit sounds awesome in the Scope enviroment, but the PCM90 has SP/DIF I/O's and operates @ 24bit and is a Lexicon PCM91 that is missing the AES/EBU I/O's and a few algo's. The detailed clarity that this provides has no equal in hardware or software, and if this price remains where it is, it is a steal. I just got lucky with the purchase of a PCM81, or I would have snagged this.
I had a search for this for over a year and forgot until I saw my email notification.
If you really want to make a big difference in your recordings, snag this FAT BASTARD.
