Think of the modded Benchmark as a double the price Apogee wannabee, lol.
I agree. If you don't like the precision of Benchmark and want something more "musical" then why buy a benchmark and mod it? Lavry DA10 is another less precission sounding or "smoother" DAC option that has some people who prefer it to Benchmark - its in your price range without mods so try that too (with 30 day return).
