I would suggest the OP to seriously Consider the LM-845 Premium Version. Bypass the built in Pre-amp with out outboard Pre-amp.
You can also buy a outboard pre-amp later, The LM-845 Prem Version is a better class better reliability unit than the local Chinese LM version that is being flogged for pennies by Chinese Distributors on Aliexpress and other Chinese sites.
Stick to a dealer, this way support and parts will be free. The Premium version was built for higher reliability and is sold at a higher cost from factory.
