That's one thing. The other thing is that "a forwardness in the upper midrange and lower treble" is a universal assessment nor is it supported by measurements of the amp. Personal preference may be the issue and that cannot be discounted nor should it.
The problem is in the term "better." There are many other excellent amplifiers and I will not deny those who choose other than the Benchmark. What, specifically, do you need to fix or improve or, alternatively, how does the current amp fall short?
Why is that hard to believe?
Soundstage? Unlikely to better than a single stereo amp.
Separation? Only if the separation of the single amp channels is inadequate.
Better performance? Too nebulous to say.
I've added a second and a third but my reasons were based on the ergonomics. There...
If you have analog sources, you have to digitize them. OTOH, depending on how you implement the DSP, it may have multiple inputs or you can arrange a switch.
Bottom line, though, is whether the value of DSP is worth the price of digitizing your analog sources.
No rational configuration places the DSP after the DAC. Why incur redundant A/D/A if you already have a digital signal?
Technically, even changing the volume in the digital domain is DSP.
Oh. I can see where analog fans might find the entire prospect of digital conversion and re-conversion an issue but, for digital sources, the actual DSP is benign. Of course, anything can be overdone but I don't buy it that the mathematical manipulations of DSP are more pernicious than the...
Were these really Grados? Aren't they open cans? Were you tested in an isolation or anechoic chamber?
Open air testing, even with sealed headphones, is unreliable since the seal is poor.
Interesting. When I was settting up the CR-1 Active Subwoofer Crossover with multiple subs, JL recommended that I set the crossover above the range of port output. They based this on the premise that the resonant port was the least controlled range of the main speaker. Letting the sealed subs...
