hi, I was wondering if any of the diy amps produce decent sq. The amp specifically I was thinking about building is the CMoy amp. Originally I was thinking about buying a amp in the 100 to 300 dollar range. Thanks for your help

I have a new unopened pair of scl4s back from a refurb replacement and I was wondering whether you all think I should try to sell them in hopes of buying something better or be happy with what I have. I am using the headphones for mixing and live performance. Thanks for your help.
