I read the review but it's still a different device, isn't it?Sabaj's A30a is identical in basic design to the SMSL VMV A2.
I think the A30a is a little more advanced because it's a newer design.
SMSL VMV A2 Review (Stereo Amplifier & DAC)
This is a review and detailed measurements of the SMSL VMV A2 stereo "desktop" DAC and amplifier. It was sent to me by the company and costs US $999. VMV is the higher-end brand in SMSL lineup. The look and feel of the A2 is similar to the latest line from SMSL: It looks nicer though in...www.audiosciencereview.com
Would have loved a test!
But yeah, this brand definitely better than Topping in circuit design and reliability AFAIK.
