Hi,
Not sure where are you based.
There are very few reputed firms in Cochin dealing with Hi-Fi equipments.
The following information should be useful for you.
1. Hi-Fi Links
They are one of the oldest and the best dealer in Cochin. They deal with almost all of the reputed brands. Run by 3 persons came together because of their love for music and good sound, they have earned a reputation in the market for high end hi-fi equipment. If you are looking for something in a shoe string bueget, it may not be a good idea to get in touch with them.
You can get more details from their website.

Mr. Melvin is a very knowldgable person and can guide you to the right system if you tell him clearly your requirement and more importantly your budget.
2. Decibels.
They are basically Banglore based, but have an office in Cochin. Their office is behind the Parthas showroom on M.G Road. They deal with Sonodyne ( the only dealer), Yamaha, CA, and some other speaker brands. They have a decent demo room.
3. Best-O-Fine.
These guys are not into HI-Fi. They are just a dealer for Onkyo products and if you go there for a demo, you will find them running around to set up a demo.
Regarding Bolton, I am not sure. Most of the local electronic shops deal with this brand.
Then there are assorted small time consultants and individuals who set up HT systems based on your requirements.
Thanks
Rajendran Menon
