Bookshelf Speakers for Luxman 590axii?

+1 for Fritz especially for it's sound quality and easy to drive nature.

I was recently reading a "bookshelf speaker with lower power tube amp thread" (20 wpc I think I remember) on this forum, and the subject of Fritz Carbon 6 or 7s with 4 or 5 wpc SET amp driving them quite well. I remember @atmasphere was the one who posted that he was using the low powered SET amp to drive them, and then the owner of the company (I am not sure if Fritz is first or last name) posted to the thread and said that 5wpc would drive them.

@immatthewj I wasn't using an SET for that; I'm not a fan of SETs as they only have about 20-25% usable power and have troubles making deep bass, as well as being physically large for the power they make.  The amp I was using is a class A, push-pull design that is also fully differential. It has a much greater amount of usable power and sounds a lot better than any SET of the same power if other testimony is to be believed. 

@atmasphere , OOPS!  Once again--my bad!  When I read 4wpc I just ASSUMED SET.  

@immatthewj I get it. I was looking for a smaller tube amp and I found that SETs that could make 5 Watts aren't small. The amp I'm using can sit on a sheet of notebook paper with room left over. When you compare PP amps that make the same power as SETs you find SETs really don't have any musical advantage- the PP amp (if designed properly) will be able to sound better in every regard. But most people don't compare amps of the same power when comparing SETs to something else...

@sunshdw - Thank you for the suggestion. I'll absolutely take a look at them. 

@jastralfu - Quick question for you. Could you describe the differences between the Falcon's and Fritz speakers? Anything you'd describe as sort of fundamentally different between the two? 

@erik_squires - Thanks for the recommendation, Erik. 

@immatthewj - Thank you for the recommendation on the thread. 

@yogiboy - I've read great things about those Falcon Gold badge speakers. Do you have any direct experience with them? Would welcome hearing about your perspective on them if you've heard and/or owned them. 

@paradisecom - Thank you for recommendation on the Omega speakers. It's a name I've seen in the forums but have not yet researched. Will do so. 

@jimmy2615 - Thank you. Based on an experience of having purchased what I feel is a mismatch between Amp and speaker, I've been particularly sensitive (maybe overly so) on the question of whether a given amp can really drive a speaker. @atmasphere - Atmasphere has kindly and wisely helped me understand how some amps/speakers just simply have better synergy. 

But I guess I've come to a personal conclusion to avoid "starving a speaker of power." It just seems, from my very limited experience, that most speakers perform better when fed enough watts and current to really open up and demonstrate their strengths.
