Hi all!
I am a new member of this wonderfull forum and a beginner of the Hi-Fi systems
I work as Electronics Engineering but, unfortunately, not in the field of audio systems 
I have a pair of Sennheiser HD598, from many years, drived by a Behringer UMC-202HD, where the usage is Music, Gaming and Film.
I like the HD598 but in some situation lack of somethings, therefore I have just buy a pair of Philips Fidelio X2HR that should have a better bass extension
.
Can have sense to buy a better AMP/DAC respect the Behringer?
I have read about the Topping DX3 Pro+ or the combo SMSL SU-6/SH-6. The budget therefore is under 300$ (lower is better).
Will be a substantial difference respect the 202HD, or will be only some little differences?
Thank you very much in advance for your time and help!
