JDS Objective 2 (O2) Headphone Amp V1.1 Kit Assembled

I ordered this Objective 2 (O2) Headphone Amp V1.1 Kit by Nwavguy from JDS's website earlier last year. I've assembled and tested it, while it is fully functional running in specs I'm not a fan of the op-amps used in this design. Will do 20Hz to 20kHz flawlessly, perfectly flat. I like a bit more coloration and fun in my amps. Rather sell it and buy another amp rather than swap out op-amps till I find a sound I like. Bought for CA$172 (US$126.55 Shipped). Not charging extra for assembly time (3h), or the additional $28 of duties I had to pay to import the parts. I forgot to order the front and back plates for the case. JDS has them on their site for 2xUS$1.99. Asking $120 FIRM. Pickup only. Cash only. No trades.
