HI, I am thinking on getting a used Conrad Johnson pre power combo after reading good reviews of them. I am planning for MF2500 power amp and PV 14L preamp which I am planning to use for Dynaudio focus 220. If someone had experienced the combo or other products from this brand, please guide me about these. I am looking for a system which can go for a long term and i dont need to change them. I can see the power output is good 250 watts. How does it compare to the modern pre power combo and stereo integrates? I am more into rock, Pop and music which has good base. Not heavy metal though. Also, do we have support and repairs available in India, if something goes wrong since this is going to be used amp as these are older models. I dont see myself going for a tube power amp in near future but I am ok with tube pre ( which is the case with PV 14L). Also, I wanted to get an idea about a fare price of the pre power combo in good cosmetic and working condition. Any inputs will be appreciated. Thanks
