I ordered 3 new Paia modules which arrived today - amazingly, customs only held them up for 2 days! I ordered a Noise Source, a Balanced Modulator and a Passive Mixer/Splitter from the new 9700 series of Frac modules. The Noise Source & Balanced Modulator are to go in the main Frac case, and the Splitter is for a separate sequencing case.
Looking at the new modules, I'm very impressed with the build quality. In fact, I don't know how they manage to sell them so cheaply. The front panels are very nicely done - they have the same 'mottled' paint effect as the 5U MOTM stuff - a very professional finish.
They are also very shallow - of the 3 I got, the deepest is barely 2 inches.
I've already given the Noise Source a quick test - it gives 3 different outputs, 2 of which are filtered versions of the main White Noise. Most of the output level seems to come from the far end of the pot travel, but most of the time this will be fed into a mixer or into the Bugcrusher, so I don't think that's a problem.
Based on these 3 I'd recommend getting a few of these modules - they are great value (even when having to pay customs duty).
