Why would you spend $1000 on an amp for $370 speakers? That doesn't make much sense. Just what features/connectivity do you want in the amp? The Klipsch speakers can be driven well enough by even your SMSL amp if you're good with the features that amp offers, altho you could get a lot louder with a more powerful amp; you might just use what you have for a while and see if it suffices.
The Klipsch is $200, much more reasonable, and appears to already have a dac built in and even has a phono stage; you could probably use your other dac if you wanted to by using the analog inputs, tho....here's a review of the Klipsch unit

I would suggest not buying silly Audioquest cables, that will be money better spent on things that matter.
