RE: Non-Native PCI Mobos

If you must change your MB, it seems your choice is very limited and the H61 MB should be a good choice. It advantages are non-presence of unnecessary/unwanted peripheral (only 2 SATA and 2 USB controllers), hence less current consumption. I will listen to Julia@ on the H61-S2h and H55-UD2H respectively and compare with my USB converter to confirm if there is any degrade of SQ.

The H55M-UD2H is a fine MB. I had no intention to change it until I tried the H61 MB, but I'm looking at H67MA-UD2H-B3, a discontinued top-of-the-line product with an 8 phase (12 chokes) CPU power circuitry. It should sound much much better than its elementary counterparts.

I like the latest Sandy Bridge chipset/CPU because the current consumption is reasonable, hence quality power supply is made more affordable.

Regarding the H55M MB and i3 530/540, I just found some second-hand H55M-USB3 in China, which was a top model with low Rds(on) mosfets, similar to the H61/67 series. Since the power circuit is superior to UD2H, it may sound better. The MB is being shipped. I'll try it when I get it.

I guess our CMP machines are moving on as new CPUs/Chipsets roll out and products discontinue. I'm looking forward to the 22mn CPU technology coming next year. I guess we may be able to power the 5V rail with 500ma of current.
