TC Electronic Impact Twin
I bought thís firewire interface as an upgrade from the Maudio Audiophile 2496. The difference in the conversion is very noticable (I read the converters in this unit are the same ones used in the RME ff400) and I was very surprised with the quality of the preamps. Guitar, Bass guitar and hardware synths record absolutely clear, it is a pleasure to record (wish it had more DI inputs).
The unit is absolutly sturdy, I have no quality complaint. The front panel has some additional functions for monitoring (compressor and some reverb) and mixing (mono, stereo)
It is future proof in terms of expandability (ADAT), which was an important criteria for me and it also includes MIDI ports. I have connected my synths (K2000 and Emax without any problems).
Regarding the driver issues of the previous generation (Konnekt24), I have not had a single problem with this unit after owning it for more than two years.
The unit also comes with a software tuner, wich is very handy for guitar- and bass players. The monitoring section also comes in usefull. The unit also has some software filters and an adaptive EQ (assimilator), although I have not used these.
I would highly recommend this unit to anyone looking for a flexible "all in one" unit for their home studio. Disregard the bad driver repution of the previous models, this unit has been very faithfull!
