Hey everyone!
Having just started building a new set of speakers, SBAcoustics SB20FRPC30-8 fullranges in a TL/MLTL type cabinet, I now have to find a good amplifier to pair it with. Given that the speakers will be somewhat on the efficient side (92db), I was wondering about what I should aim to feed them with. I've been using active speakers for years so I don't own an amp at the moment. I have access to one of those tiny, awful Nobsound bluetooth amp and that's it.
Since I'll be listening to them at nearfield levels most of the time, only ever cranking them up to reasonable levels once in a while, I figured I should look for something in the 5 to 30W ballpark. I was tempted to just get an off the shelf Loxjia A30 or SMSL A50, but I don't want to be underwhelmed by my new speakers by not pairing them with the correct device.
I've been browsing on here left and right looking for clues but I'm still at a loss.
1) Is it a good idea to pair efficient speakers with something more powerful, say, 100W? Does it mean getting a better, cleaner response and more dynamics?
2) I was interested in the two amps mentionned above because they both have bluetooth, but then, I read in a few places that using bluetooth will sacrifice extensions in both end of the spectrum, is that true?
3) If I were to go with a DIY amp, how easy would it be to work out a competent bluetooth system for it? (I have a USB dongle DAC, but I'd rather go full wireless unless it means too much sacrifices)
4) Is it even worth my while to be looking at building a DIY amp for under 200euros all inclusive? Or will I get similar results minus the hassle by just getting the Loxjie?
I most of all care about resolution and clean bass extension. My entire design choices with the build I'm starting right now are aimed toward that goal.
Thanks in advance for your answers!

My "knee jerk" reaction is to avoid BT then if that's your goal. I'll admit, I know nothing about bluetooth.
On the amplifer side, there are a bazillion options, diy or not.

Right, you may only need a fraction of a watt in average playback, but with up to +20 - 30 dB of dynamic headroom depending on the recordings you might need a class A/B amp with at least 10 W class A and the rest for 'dynamics'.
Anyway, here's one of many good threads here and more on the WWW with math here.

The TPA3110 board $1 cost once converted into ABD mod. is the best I propose.
