Low powered integrated recommendation

+1 on the Sugden A21 signature. 
unless you need power on/off or source switching on your remote. 

Bruh, the Zest from Vista Audio is a fantastic little class a/ b amp with a very small footprint that puts out about 30 watts per channel. Check out Steve Guttenberg’s review on it.

I’d consider one of the relatively low wattage class A integrateds from Accuphase. 
 

However, since it’s never bad to have more power than you need, I’d personally save a bundle over some of the really pricey choices and grab a like new/preowned Hegel 390 for about $3000. Or splurge for a 590 for a still very reasonable 4500-5k. 

My favorite integrated amp is the Synthesis A40 (pushpull tube amp using KT66 tube).  It comes with a very good built in DAC.  This is a warm sounding amp with a very lively, punchy sound.  However, the chassis is on the large side (a good thing, in terms of dissipating heat).  Input selection and volume can be done by remote control.  Audio Note makes good sounding integrated amps too, like the Oto (pushpull EL84) and the Soro (pushpull 6L6).  

I am not as big a fan of solid state amps because most sound flat and lifeless when played at the same volume level as a tube amp; they must be played louder to come alive.  Still, most are otherwise quite decent.  For modestly powd solid state, the Sugden suggestion, above, is quite good, and I would add Lavardin.
