I have AKG-701 phones w/ Musical Fidelity X-Can v8 amp and power supply, bought because of a good review. I read the bass is weak until phones are broken in, so I crumpled up newspaper in a plastic bag the size of my head, put the phones on the bag (to make this process as realistic as possible), used my old amp (Audio Alchemy HPA v1.0 to save wear on tubes in my new amp), put CD's on repeat, and played for 250 hours while I was out. This took several weeks, but I noticed no improvement. Does anyone have this phone/amp combo and what is your opinion? Is it possible this is not the best amp for these phones/is there something better? I get better bass response with my $20 phones and Sony Walkman & Discman players. Thanks for any opinions/advice.
