Monitors for Pass Labs 60 INT

@pops I have not, but very curious about how they would pair with my amp. I don't have any local dealers to demo them. The reviews seem to note these are fairly easy to drive in a small/mid room. What's your experience with them? 

@honeyooi I have considered these, but thinking they are slightly too large (physical size) - i sit relatively close to speakers. Size aside, do you have experience with these and pass?

Udisa:
Size wise M30 not too bad,even own bigger C7 on my small room,mine 10x9 similar to yours.
Been driving them with tube at 80w ,enough power!
Been own pass labs INT-150 ,yours pass will drive harbeth with easy.
Is size matter maybe I've try the P3 ,smaller in harbeth line.
You can see my set up on system,mine can only take from angle side cause I can't take from front cause too close about 6'.

I think you should consider the Wilson Benesch speakers. No relation to seller, but there is a pair of Discovery for sale on Audiogon at a good price. About 88 db efficient and should be a good match.

Haven't seen Sonus Faber mentioned. Some great used available plus newer monitors.
