Non-Fatiguing bedroom system?

BTW I forgot to note my budget would be 1 to 2k (unless i fall in love!)

Thanks!

I have an office system that I think meets most, if not all, of your requirements. I spend more time listening to it than my main system, often for most of a day and never tire of it.

Jolida FX10 EL84 tube amp
Simaudio 100D DAC
JohnBlue JB3 single driver speakers

The source is an iMac connected by its digital optical output to the Simaudio DAC.

Even though the FX10 output is 10 watts and the JB3s are relatively inefficient the sound level in my 10'x12' office is more than adequate and I never have the volume control above 10 o'clock.

The JB3s are beautifully built and image like crazy, even though most pictures don't show them, they do have black round grills to cover the driver if you want to make them less conspicuous. They have surprising bass for such a small speaker, I've never been tempted to add a sub in that environment.

I did open up the FX10 amp and clip the leads to the blue LEDs under the tubes that I found distracting and, frankly, silly. I don't use the glass enclosure, either.

I bought everything used for less than $1K, not counting the iMac, but even if you bought everything new you'd be under your $2K limit.

Can’t think of a better place for a fatiguing system. :-)

How about a NAD316Bee driving a pair of Pioneer SP22 speakers. At less than $500 leaves $$$ for source.
