At the moment I've a shure SE215 in-ear partnered with a Fiio E17 USB/DAC/Amp. Would upgrading to a portable Philips M1 be better partners for more listening pleasure?
Or is the E17 together with the AKG K450/451 a better match with regard to component price-quality match.
Also looked at the AKG-K550 full headphone but is more expensive and maybe not easily driven by the E17. Maybe some higher quality dac/amp is needed for such pair of earphones.
Regards and hope to hear from you all
