Hey guys,  
	 
	Im new here, and I was looking for an opinion.  
	 
	I recently got some L700s as an upgrade for my 207s, and I was thinking about upgrading the energizer as well.  
	I am fairly confident at modding circuits, but I am unable to get non-stax branded amps.  
	 
	I am currently looking at used stax amps and found a few options.  
	323A for 25000jpy 
	323S for 36000jpy 
	727A for 68000jpy 
	 
	In your opinion, which will end up sounding the best keeping in mind that I am only driving lambdas? 
	 
	Thanks for any input
