This was your response. So do these specs mean you can hear the difference or just on paper? Any real world experience with their sound not being up to par? Have you had any experience or spec comparisons for Outlaw's 990 which is what I currently have?
My personal experience was comparing a true Class A Analog Preamp (no fancy DSP, tone controls, EQs, etc.) to receivers. I was trying to figure out if this preamp had CLEARER sound (with volume levels matched). My conclusion: Yes, the analog preamp had significantly clearer sound. Then I looked at the specs in RESTROPECT and found that the analog preamp had better specs, especically in CROSSTALK (-90dB) and Linear Frequency Response (20 Hz - 20 kHz +0.0dB, -0.1dB). I only noticed these specs recently.
Deep inside I was truly HOPING that an AV Receiver or Pre-pros (with lesser specs) could sound just as CLEAR as the analog stereo preamp. It would have made my choices a lot easier. I would have gotten the Onkyo 875. Things would have been simpler. But no. That damn analog preamp had to sound significantly better! Bastard preamp!
I did compare the sound quality of the Outlaw Pre-pros vs my analog preamp. The Outlaw sounded as good as the Harman Kardon AVR247, but still cannot beat my analog preamp in terms of sound clarity IMO. So I sent the Outlaw back. I cannot believe Outlaw charged me for shipping that thing back!
I have also compared the Onkyo 805, which I assume sounds just like the 875. Again, very good sound, but not as clear as my analog preamp IMO.
But perhaps I'm just being way too picky. And my experience is not a blinded study. Just my opinion. I'm sure they all sound the same.
But my thought was, if a $600 Parasound analog preamp can have specs as good as my Acurus analog preamp and as good as the high-end preamps, why can't the Emotiva preamps or pre-pros be as good?
Same with Outlaw pre-pros. The F.R. of the Outlaw is +/-1dB, which is not as good as Acurus (+/-0.1dB). Outlaw doesn't even list the Crosstalk/channel separation, which is one of the most important specs.
So, in real life listening, we probably can't hear any significant differences. Just because I thought numerous times that I could tell the difference really doesn't mean much.
