The UA-1A has an internal loopback connection to allow monitoring of recorded signals, this plays havoc with MLS measurements -> you will find a reflection at about 60% of the initial impulse after 9.85ms and a very strange looking low frequency response. It is possible to fix this by making a mod to the card, specifically remove R28 and R35 (both 47k SMT parts). If you are not competent in modifying surface mount PCBs or would like your warranty to be worth something then making this mod cannot be recommended, but with the mod carried out the UA-1A does a very reasonable job. Note that the UA-1A is stricty at 44.1k device.
