Has anyone ever swapped a Becker 612 for a Becker 1480? While my current 612 sounds reasonably ok if playing music not too bass heavy, it nonetheless underwhelms, as the deck no longer works and is just shabby in general. So, after researching costs to refurbish the 612 vs buying a brand new, ridiculous looking 3rd party head unit marketed to the wanker generation, a refurbished 1480 is looking to be a very viable option. Ungarishly high-end and smart looking -- handsome, if you will -- it is ostensibly the right fit for my 84 300SD. And, from what I understand, its sound quality is far better than that of the 612 when coupled with the the appropriate speaker upgrade.

Does anyone have experience with a swap like this? Any forseeable compatibility issues between the two? My biggest concern is that the 1480 uses an external amp and fiber optics for speaker connections instead of traditinal coppper wiring, either of which will derail the Becker swap.

Any advice to this idea is appreciated. Thank you for your time.
