Finally got mine today. The package was lost twice and then the vendor refused to send out another one coz they've already lost two units. USPS is probably the one to blame because it was meant to be sent overseas but ended up in the US each time. Fortunately the MD customer support team are very nice and managed to send me the sample unit they have for photo, and gave me a partial refund of $25. I'd like to thank Kat and Kelly again for their help. GO 450 does sound better than the Monoprice DAC/Amp. Finally, as GO450 is officially discontinued, you should look elsewhere if you still want one, or get the latest GO V2, which is more expensive, though. Also, LH Labs seems to only enjoy clearing stock of discontinued products on MD, so we only got to drop each model of their first-gen GO once. I guess it would take at least another year for GO V2 drop to happen here.
