I've decided to buy some AKG K702s and I need a headphone amp to power them. The headphones will be connected to my Panasonic AIO home cinema kit via the headphone socket. The bass is lacking due to the limitations of the headphone socket, so ideally need an amp with bass boost. The amp will need to have a 3.5 mm input socket and powered from the wall. I was initially going to buy this amp but it lacks tone control, would the bass be enhanced if I used this? https://www.amazon.co.uk/gp/product/B00A2QLMX6/ref=ox_sc_act_title_1?smid=A3T2PXX210KPYE&psc=1 I have a budget of ~£60. I really don't want to spend a fortune so I have this budget. Thanks.
