Not to hijack your post but below is a Post that I started at PSW about the new XTi amps.
Maybe David will respond with Information as to exactly what is under the hood
and what topology the XTi amps use.
We / I would also like to know the official standing of the CE Series of amps.
To help you with your question.
Here is the info on the DSP:
EQ: 4-band paragraphic (not Parametric EQ as wth the DRPA) per channel, boost/cut ±12 dB.
Also adjustable high and low shelving filters.
Filters: Highpass and lowpass per channel. Butterworth (only) 6/12/18/24 dB per octave. High and low shelving filters, one per channel.
Delay: For signal alignment of driver; 5 mS total delay.
Subharmonic Synthesizer: Adds low-frequency content.
Output Limiter: Prevents clipping.
Presets: 10 user speaker presets.
EarWax, check out this link, you can also download the Manual.
