I own two Jolida int. amps. The 102b and the 301. Both have performed and sounded superb. I called Jolida a few times before purchase and everytime I called I spoke w/ a live person whom answered all my questions fully. I had a good feeling of dealing w/this company. I sensed that they took pride in their work and would stand by their products. Also, they are located not too far from where I live so in the event of service work...I've owned both these pieces for less than a year so I can't comment to their long-term reliability, but I feel confident they will provide many years of service.
