Am I correct, from reading this post, that basically all of the small portable pres (SD-MP2, Sax, Aeta PSP-3) are discontinued? Is there anything out there that's still in current production?
The Sound Devices MP2 was discontinued and replaced by the SD Mixpre, which is very, very similar and is still in production and available via retail.
The Aerco MP2 and new Naiant littlebox are still in production. Both preamps are made by one man shops and can have a little to a lot of leadtime to get one. The Aerco MP2 I guess can take several months to get built, but Jerry is still taking orders. Jon at Naiant is still building the littlebox, but had to put aside current production runs while he works on other things. He should be back building them in a few weeks in mid-October.
And depending on what you call small and portable, there is still the Grace Lunatec V3 and the Neve Portico.
