Coincident speakers 14 Ohms - What amplification to use when streaming Tidal.

A Bakoon SCA 7511 integrated amp should match well.They are solid state class A/B but current drive,have zero negative feedback and like SETs have a high output impedance .They do not sound exactly like a SET but are probably more like them than any other SS amp I have heard.Only 15 watts but an absolute quality 15 watts and  if your speakers suit are capable of extremely high end sound and are very affordable.

97 (or even 94) dB sensitivity is VERY efficient.  Compared to a typical 89dB speaker that means you need something like 1/4 to 1/8 the power for the same volume. 

An "8 ohm" amp is simply the load it is rated into.  Ohms are a measure of resistance. The higher the easier to drive. The lower the harder. Zero ohms is a short circuit. In practice nearly every amp (except tube amps) is designed for a s low an output impedance as possible -- on the order of 1/4 ohm (0.25 and below). Its the other way around that's a problem - a high impedance output tube amp cannot deliver high current.  A 4 ohm or  (yikes) 2 ohm speaker demands lots of current.  No go, like an under powered motor.
The good news is that at 97 dB it wont need much current anyway!(for the record current = voltage / load in ohms).
Bottom line a really good solid state amp ought to dive anything. Within reason mine will.

97 (or even 94) dB sensitivity is VERY efficient.

I would characterize 97 as the high end of moderate efficiency and 94 in the median of moderate, with 90 at the bottom. 89dB this at the higher end of low efficiency, and 97-98dB at the lower end of higher efficiency as there are speakers that are 107dB 1 watt/1meter...

just some data points for respected hgih end speakers:
Vandersteen 2 - 90dbTotem 88dbMaggie 7s 86 dbVienna mozart 90db

are there speaker at 107? Probably.  But its rare and suggests it was optimized for other than sound

are there speaker at 107? Probably.

Such will be horn-loaded. The Hartstfield loudspeaker, which uses JBL components, is quite respected and is 105dB.
