Yamaha RXV2500 vs RXV2600 diff in sound

[mtrycrafts]

My Yamaha 3090 has problems with it's source select motor, so I'm looking at one of these as a replacement- especially considering the killer deals on the discontinued 2500! Not that specs are everything- but is Yamaha getting worse?

Comparing my DSP-A3090 and my Dad's DSP-A1 versus the brand-new best of everything RX-V2600:

RMS Power 8ohms, 20-20k @.015% THD vs. @.04% THD
Damping Factor 8ohms, 20-20k: 200 vs. 140
Freq Response: 20-20k +0/-.5dB vs. 10-100K +0/-3dB
THD 1V input, 20-20k: .005% vs. .02%
Chan Separation 1k/10k: 70/60dB vs. 60/45dB
Audio SNR: 96dB vs. 100dB <-----ok, this one got better
Weight (maybe a "quality" indicator?): 3090=46lbs, A1=52lbs, 2600=38lbs

Of course the video bandwidth and connections is night and day against these older models, not to mention the new 6.1 and DSP modes. Just wondering if Yamaha cut corners to squeeze all that into a $1400 box. Of course the 3090 and A1 had MSRPs over $2K and $3K....

those specs are pretty good for the new units, especially the SNR
Frequency response cannot be compared as it is not the same bandwidth, one is to 20kHz the other to 100kHz. I bet at 20kHz, the other one is much closer to .5 dB, maybe even better

They are both transparent, that is all that matters.
