  1. Hi Yung,

    I have been following you guys for some time and I would just like to say, thank you for your work here and sharing your reviews and comparisons. You are just about the only group who actually compares like products in a systematic manner. As a former HiFi dealer, we used to take great care in not only comparing products in the evaluation for what to carry in the store but we went to great lengths to find proper combinations of components etc. It is a sad situation that this is just simply not done for the most part in the majority of the market. Publications, be it in print or on-line nor dealers take the time for the most part. So, thank you for that effort. It takes time and dedicated effort and it is very much appreciated.

    I am curious how you would compare the ATC SCM 20A to that of the equivalent monitor in the PSI line? Also, in the ATC passive line up, how would you characterize the differences between the SCM 12 Pro and SCM 20 Pro?

    Thanks, again….Best regards….John
