The title states it all. I want an amp that will also mellow out the highs a bit. A tad too bright for my likings. BUT I would like to leave the lows as is or maybe even enhance them. I love me some bass. I've read around, and a lot of people are saying that tubular style amps are great for cans with too much highs. I found this on amazon http://www.amazon.com/Bravo-Audio-Multi-Hybrid-Headphone-Amplifier/dp/B00ADR2DTG/ref=pd_cp_MI_1 and seems like a good deal (sold out right now, but usually around $60). So, what do you guys think?
