CrinEar Protocol Max Portable DAC-Amplifier

Faulty after 6 months of daily use; bad warranty policy.

Bought it in december to be my computer desk dac/amp. In June, left channel started to drop or lower intermittently. I did test several headphones and source devices to isolate the problem to the Protocol. I was able to record a video of the problem and contacted support. I have now learned that to do warranty claim for Crinacle product under the 1 year warranty, you need to pay for the shipping to send back your faulty product to get a replacement. I am disatisfied by the product and I don't think a person wanting to buy a long lasting and thrusworthy product should buy this. I understand this is a small company, but you should take care of your customers. Will not buy Crinacle product again.

A worthwhile purchase

My favorite part of the protocol max has to be the sound signature. It has a neutral sound signature so it pairs well with most iems. Staging and sound separation stood out to me the most. It also has great build quality with an all metal body. Power is sufficient to drive any iem or headphones. Overall for $120SGD, it is definitely worth your money. Oh and the people working at Hangout audio were really friendly as well so plus points for that!

It's my first amp/dac and whenever I use it on any mobile phone, tab or laptop it's just enhances my music way better than inbuilt device dac/amps it has soo low distortion and top-notch clarity. I am searching for its protective case but have not found any hope it lasts. it's easy to eq via browser.
