thnaks guys for suggestions. Yesterday I Visited Echo Electronics on Law College Rd at Pune to meet Mr. Pathak. I was really happy the way he explained all the products he has and never eager to push something after knowing initial budget. So for now, he has suggested to go with Blau HU + rockford/blau comps for front, give it a try for a day and if not convinced then switch them to rear and go for Infinity comps for front as I initially planned. he also has a few other brands as Audio dynamics, Boston, Clix, Blau, Infinity(on demand) and some more German brands too.
