4 ohm (or 6) Bookshelf speakers. Pass Labs 30.8

I have TAD ME-1 and technically they are bookshelf size although I think they come with the stands. The sound is incredible.

Jackd,
    Found a hometheaterhifi review that compared the 30.8 and the x150.8, and it really secured my interest in the xa30.8 over the x150.8.  Also I did follow up with reviews comparing 30.5 to the 30.8.  This also explained the class A and AB for both and bumps with what your saying.  This has been very helpful.  My listening levels are low.  I enjoy long hours of listening after work, while relaxing, and reading online.  Rocking out for me would be volume loud enough just to the point where I wouldn't hear a person speaking from 5 feet away or so, rarely.  I was able to get enough volume out of my Bose mini when I had that, those little rechargeable ones.  :)  

    Plowed through reviews, did see a lot of identical speakers among listeners, most were panel or floor, and few bookshelf (which partly worried me) but now that I have learned I have more freedom then I thought I did with bookshelf's, I'm not as concerned.    Maybe most folks that have these amps have more room in their home for larger setups so bookshelf's just are not as popular for that reason?  No matter.  

   Thank you for helping clarify this stuff.  Now I feel like this amp is way to good for me!  Kidding.  

Synergy between amp and speakers is paramount. If possible, audition your amp with prospective speakers. Some combinations work well together and others not so well.
You didn't mention your price limit? In my system I use a NAD integrated with a pair of PSB Imagine B's ($1000/pr). Synergy is very good with NAD and PSB. Do some research and you may find a good match with your amp.

I've never owned a Pass amp but have a couple of friends that have owned many of their models and they both think that the 30.5 and 30.8 are the best all around sounding amps in the line if their power works for you.  One of the reasons I recommended the Buchardt is that you can listen in your home for 30 days and they pay the shipping both ways and refund your money if you don't care for them or they don't work for you.  I am keeping mine.  Another model to look at is the Reynaud Bliss Jubilee and you can call Bob Neill at Amherst Audio and talk to him about it as he has personally owned Harbeth's, Spendors and Audio Note's in addition to the Reynaud's. Both speakers will work well with the Pass and are extremely musical. 

Synergy, ok.  I will have to focus on that when eyeing speakers.  Given the cost of the amp, used, it will be a bit after I purchase it before I get speakers, so I hadn't totally thought that far, other than at least validating most book shelf's will work ok.   Tentatively, I wasn't planning on anything over $2k/pair, not that I need to or am aiming to go that high. I will have to find a Pass dealer, probably just buy the speakers there, and I really want/hope I can listen to some speakers with the 30.8.
