Accuphase Amplifiers - members opinions on their class A- A75 amp and the a/b P-7300 amp


I enjoy Accuphase's sound and I just retired and will be moving so I thought it would be a good time to trade up. However, what I do not like about Accuphase is the fees and tariffs and markup's on their UA Authorized products entering the USA. That is a shame in itself but best left for another time and thread. I do have my Accuphase P-6100 up for sale here now and enjoy that sound due to the MOSFET output stages if I have that correct. Detailed but smooth and accurate...… So I would like to hear from other Accuphase owners who have purchased one the above mentioned amplifiers and why they chose that one over the other one. The rest of my system is all Accuphase and my speakers are the Wilson Benesch Square 5's.  87 sensitivity 6 ohm nominal and WB recommends a minimum of 100 wats ( the A-75 is only 60 but pure class A ) My concern over the A-75 would be the damping factor and really of any class A amp in which Accuphase has noted that factor has been improved with this amp and the speakers base response to which amp I possibly choose. ( or, I could just keep the P-6100 ) We all like great bass and I am a big Allman Brother Whipping Post fan and I want to hear Barry Oakley nail that into each and every time ! I use that song as a way to evaluate bass in my or any system I listen to. Thank you in advance and I look forward to your responses and opinions. Stay well and safe out there

Thank you ; mijostyn much appreciated but still wondering if anybody has done a personal comparison of these two Accuphase amps and what their thoughts were and why.  
garebear, I would stay with the 6100 until you can afford a more powerful class A amp. Your getting about 160 watts/ch out of the 6100 and given you like to get whipped my guess is you will be disappointed with 90 or so watts/ch. You are a rocker. There is never such a thing as too much power.
…...thank you again mijostyn and it has nothing to due about being able to afford one of those two amps nor about the power.  I am however more interested in the presentation and or musicality of going with Accuphase's class A powered amps or their a/b amps. I guess that current owners of either one of these amps never compared or thought about the sonic differences. Stay safe...      
garebear, I have both, “A" and “AB" Class Accuphase amps, p4500/a48, and somehow mostly in use is p4500. These amps have pretty much the same improved input stage designs, but completely different output power stage circuits. I found A48 sounds little bit more “liquid”, on some reference quality sound tracks, but overall both amps are very good, transparent, punchy and “airy”.

@westcoastaudiophile are you still using the P4500 more often?  Is there anything in particular you like more?
