      Hi. I've been looking at PDX-F4 as perfect partner for SPR-6oC speakers but the price is too high. How does sound quality compare with MRX-F35. The lower power output would be O.K. Busking is the aim.


      The PDX-F4 will be the perfect match for the SPR60C as it produces enough power for them. With MRX-F35 you will only get half of the power.
