help please? connecting power amp to streamer/dac without preamp?


Hi,
I've been seeking a high powered quality integrated amplifier at a good price without much luck,and now have an opportunity to acquire Parasound 2250 power amp instead.

I would like to connect this to a Bluesound Node to run a pair of tower speakers.  No preamp and nothing else in the chain.
Can someone explain any drawbacks to this setup?  I'm presuming the volume increments only using the Node will be limited compared to having a preamp in the chain, is that correct?
I can likely acquire a preamp later if required.
thanks in advance

While it appears as though the Bluesound uses a 32 bit chip, which ordinarily would have extra chip data to avoid bit stripping with volume attenuation. But, the Parasound has a 1 Volt input sensitivity for full output, which would require a halving the 2 Volt output of the Bluesound to play at full volume. It might work but you might have a somewhat delicate limited volume control range, and might encroach bit stripping at low volume levels.
^An analog volume control might bring into play other considerations.
Ideally, one would find an amp that meets the loudspeakers requirements into load, and that has an input sensitivity for full power output that matches the output voltage of the high bit DAC, and use appropriate cables.
