Benchmark Performance, Budget Price

This is the O2+ODAC Combo assembled by Mayflower Electronics. The amp section of this combo, an O2, was designed by NwAvGuy, with emphasis on benchmark performance and low cost. The ODAC was made using the same principles and it's been specifically tuned for maximum performance with the O2. Together, O2+ODAC deliver reference grade audio performance at a fraction of the price of comparable equipment. The ODAC in this drop is the latest and greatest 2015 revB version, which offers significantly improved performance without any additional price.

Attention to Detail, Build Quality

Mayflower Electronics assembles each O2+ODAC combo here in America. Each unit is hand tested to ensure only the highest quality components and finished products are going out to customers. In addition to their high level of quality control, Mayflower is also able to make small improvements to the original O2+ODAC design. Looking at most pictures of the O2+ODAC you'll notice the headphone and line-in connectors are on the front of the unit. In an effort to improve aesthetics, Mayflower has moved the power connector to the back of the unit. The result is a cleaner front plate that you'll enjoy looking at.
