After almost a year checking out high end audio outlets in Kolkata - this was where I finally found my perfect combination of speakers and amplifier and high end CD player. Excellent demo facilities , professional behavior , very good services and most importantly the cordial and passionate Utsav - proprietor - made my purchase worthwhile. Its been almost 3 years now and Im more than happy with my setup.

They have the best service center for high-end audio video equipment in Kolkata.

Hi, I got the Sonus Faber Venere 3.0 along with the Marantz AVR & Power Amp. Not only was it perfect , but also Utsav made sure that the calibration was done in his presence. He was kind enough to drop in and calibrate by his own sense , trust me . it made so much difference. This guy is not only passionate but extremely knowledgeable . Though I was getting some better price for Marantz , Utsav clearly said the extra bit would definitely be worth it .And yes it is !!!Many Thanks for your wonderful support and service.My best wishes.

Nice experience! The speakers are really good. Outstanding experience at the demo room. Keep it up!!!!
