The Hafler TA1600 and Art SLA-2 both sound fine to me. I compared the two before selling the TA1600. I think the TA1600 might have a *slightly* better stereo image (not enough to write home about). I plan to use bigger monitors eventually so I kept the SLA-2 and sold the TA1600. Someone that has'nt heard an SLA-2 might make assumptions because it's made by Art. Both amps are a good value, imo. Hafler went belly up so you'll have to find something old stock or used if you want a Hafler.
