I think you'd definitely hear a difference through your Klipsch if you did that. The B10 are rated 50-200W.

All well and good except the amp you link is 160W (max) into
4 ohms, but the Klipsch B10s are 8 ohms. Specifications for the TDA7498 are all over the map. For example:
Audiophonics TDA S50
2 x 50W @ 8 ohms w/36V power supply
2 x 100W @ 4 ohms and 1% THD
SMSL SA-98E
2 x 160 watts max @ 4 ohms (12% THD)
2 x 80 watts max@ 6 ohms (10% THD)
2 x 60 watts max @ 8 ohms (10% THD)
Here is an independent test from Big Wiz:
I don't want to imply that the chip amps are bad, but be very careful touting them based on their advertised power output. This particular chip seems to be highly regarded and I think it's a decent solution for a home office and they are more than capable.
The B10 sensitivity is 90 dB at 1W/1m. By way of comparison, one of my set-ups in my home office is a Pioneer SX 680 (30W) driving a pair of JBL 4401 studio monitors (88 dB). The 30W receiver is more than sufficient to drive those speakers at the listening levels I enjoy and what the Baroness lets me get away with. So, I don't necessarily agree when you state that 64W starves the B10s but it depends on what the listener's goal is.
In a near field monitoring situation, such as in an office, 85 dB SPL (with 15dB peaks) is loud enough, in my opinion, and a 25W amplifier is sufficient. I typically average about 72 dB.
