The product pages for the Waldorf Blofeld and Stromberg are up along with the Zarenbourg and Phoenix edition Qs. Looks like the Blofeld is very close to the Stromberg aside from the hardware and add on modules. I did a quick A/B of the features and the following are the main differences I was able to identify:
Stromberg:
- external audio signal
- analog filter with analog distortion*
- surround delay
- tube distortion**- output configuration switchable between stereo and surround
* Only with optional analog module a-filter with 16 analog filters.
** Only with optional analog module valve, number of tubes not decided.
