Are the ASP880 preamps the same as in the iD22?
The converters in ASP880 are the same as our iD22 design. This uses hugely upgraded Burr Brown converters with an approximately 10dB dynamic range improvement over the ASP008.
If you run the ASP880 and iD22 together you get 10 preamps of exactly the same design and 10 AD converters of the same fundamental design. There's a bit more in the signal path on the ASP880 so dynamic range spec is slightly different on that, but the sound is identical for intents and purposes between iD22 and ASP880.
