Low powered integrated recommendation

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.

Audio Note Oto SE.

Look for a second hand one. It's a single ended pentode. If you find a SE Signature, get it! Jackpot. Look for one with 4 knobs, the ones with 5 knobs are quite old now.

If you want to buy new, Audio Note has had a price increase on 1st July, before that I enquired and the new price for a Signature was £4700 rising to around £5500 now. You can find a nice second hand SE for around £2000, if you're lucky you'll find a Signature at £2,500-3500. The holy grail is the Silver Signature if you want to spend thousands more (and if you can ever find one!)

It's a 10W valve amp. I have never needed to push the volume past 50% in my small-medium room. Yes high-efficiency speakers are a good idea, but before my Audio Note speakers I've used it with ProAc D2Rs and Harbeth P3ESRs no problem.

The sound is absolutely gorgeous, whilst still retaining clarity. EL84 valves. I have owned a Sugden A21SE Signature, and while I had a lot of respect for what it did, I couldn't love it. I love the Oto SE and the SE Signature. I also have a couple of pre/power combinations (Croft/Primaluna/Audio Research) but always want to listen to the Oto.

No remote control, but I use Lumin U2 mini streamer with Leedh processing for changing the volume when the cat's on the sofa with me.

You may want to consider one of the Raven Audio integrateds.
