I am not saying the Placette is not a good passive pre-amp but if you are going to match a passive pre-amp with the DNA-1, my experience ( together with others ) tells me that the TLC-1 is the " perfect " match. It probably has to do with Steve McCormack's vast experience in the desgn of passive units starting from 1984. A lot of passive pre-amps are great on paper but you need to carefully match them with the right components. If you are only using the Placette as a remote volume control to a passive pre-amp, then you should think hard of are you seeking for the transparency & the sweet highs that passive pre-amps be able to give you, or just for the convenience of the remote volume control? I don't care how transparent the Placette's review is raving, using a another volume control unit on top of a passive pre-amp will cost you the transparency that passive pre-amps are great for.
John, you can get an used TLC-1 for less than $350, so how much can be your downside if you don't like it?
