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

I also own the Buchardt S400s.   Right now using my Anthem MRX 720 as my amp... they sound quite good.  Sometimes exceptional, amazing bass for a bookshelf.  

Mads at Buchardt answers emails very quickly if you have any problems.  I bought mine just before they were swamped with orders.  I ordered the smoked oak, but took the option of dark oaks temporarily.  So I’ve had the dark oak since April with a promise of late July delivery for the smoked oak.  They really care about the customer and have great comm.  Mads has upgraded me to the spokes oaks as well.  I really appreciate their concern.

I’ve been enjoying these speakers since April.  Just sent and email yesterday and Mads promptly returned an email update.

They are still behind a bit on sourcing the smoked oak and hiring more people.  Apparently they have updated the speakers with some tweaks as well and he believes they have improved the speakers... so I can’t complain as they will send the updated speakers and have been able to listen to these long term... they are keepers IMHO.
They had them at Xponia but honestly they did not sound as good as they are with that setup in the room.

Personally think they did a disservice to the speaker.

I WOULD SEND AN EMAIL TO BUCHARDT AUDIO and ask them, their customer service is extremely good .....my bet is they would be able to give you useful advice.

i am planning on buying a different amp as the Anthem is for my Home theatre and plan sending an email to get advice from Mads Buchardt when I take that next step.

Dynaudio Contour 20 is really good but its a pretty big monitor and very current hungry. For something smaller and a little less demanding I'd be all over some Dynaudio Special 40. 

Thank you everyone for your help, I will be looking into these speakers!  It's great to hear from everyone that has them and can speak for them and also clear up some confusion I had about the amp.  Seems pretty consistent, regardless what I do, buy good speakers and son't cheap out!  That's ok, that just means I'll have to sell some items and save longer, but hey, for an end all Hi-Fi (as long as it lasts), buy once cry once.  Thanks again everyone.  

Call Pass. They'll give you a list of speakers. They did that for me.

@jaybe I emailed them, and Kent was helpful with providing a lot of information on how to determine what was best for my set up, but did not mention specific speakers, except one that was to expensive ($13k/pr).  I was hoping by now, I would have an idea of what would work well for me, and have a base of dozens of speakers, and go from there.  

Many have mentioned here, as supported in a stereophile review, that the amps lower output is not a big deal, because it goes into A/B after 30/w and will go up to 100/w or more.  And so for that reason, I should be less concerned about ohms/sensitivity.  Well, if that is the case, and I'm running in A/B most the time for my listening, what was the point in getting an amp for it's A class properties?  And I can't really know how loud a certain any speaker will be until it's in my room.  (why the variables are important)

This is certainly one reason I'v been looking at 4 ohm speakers, to take advantage of the power bump from the amp (up to 60w/ch), which opens up a lot more options and leaves me feeling a bit more confident the amp will remain in class A.  I do prefer lower listening volumes up to moderate, but still want to err on the safe side leaving my self plenty of room in A class (plenty being relative, I know this isn't a mono block), using A/B when I'm more in the mood for loud music and won't care so much for the sound as I would in a quiet mood.  (personal preference)

I feel that the xa30.8 is still a  good candidate given my listening room is small and my preference of lower volume listening, but don't want to pigeon hole my self with a high end amp and only lower volumes in class A.  If this isn't the right setting for it, what is?  Another area of struggle for me when learning/reviewing speakers is ohms vs sensitivity. I'v read a lot and am getting much better at understanding, still hazy.  If 4 ohms bumps up the power, to 60w/ch and sensitivity means more volume with less power (sort of), where do they equal?  Meaning, is a speaker with sensitivity of 100 at 8 ohms as loud per watt as a speaker of sensitivity 85 at 4 ohms? 

The mission here isn't for me to quibble to much over the numbers (which I am because I'm not an expert), but rather, find the right threshold, single those speakers out, then I can listen them, with confidence, knowing they will work for my set up, not wasting time on speakers that certainly won't. Keeping the amp in full class A up to and at moderate listening volumes is the goal.  A few examples here that were listed were some 4 and 6 ohm speakers, all with low sensitivity though. (and why can't we have sensitive 4 ohms?)  Then there are 8 ohm speakers with high sensitivity.  They may all work well.  

This is much more important when buying used speakers that I can't listen too.  Some I can audition right here in my home and plan on doing so after I get the amp, but, I still need to make sure that the amp it self isn't so limited with speakers that will allow full class A with moderate listening volumes, that is the tricky part.  It's looking a lot better for me and this amp, but still concerned it's class A properties may be a bit limited (and that might be ok, I don't need every speaker option).
