with Pathos Classic One MKIII Hybrid Integrated Amplifier

I would not use a 6DJ8 or a 7DJ8 in this amp. The amp deserves a premium tube and recommends the 6922 in the owner's manual and comes new with it. I use Valvo Cca tubes in mine and also recommend 7308 tubes. I did not like the sound of the 7DJ8's at all.

The Pathos Classic One MKIII is 70 wpc at 8 ohm. Look at speakers with no less than 88 dB efficiency. What are your room characteristics? Are you looking for monitors or floorstander?

Great and gorgeous amp.  Like others mentioned, I’d skew toward speakers that are relatively easy to drive and that don’t drop much below 6 Ohms in impedance.  I’d highly recommend looking at Verity Audio, Joseph Audio, and Usher, all of which I’ve heard and are outstanding.  Reference 3a, Legacy, Coincident Technology, and Silverline are also worth a good look.  Best of luck.
