i agree, on the MQA front, I could care less if it supports it. I do have a good number of DSD files and have found the Topping model l recommended to be excellent for the cost (granted mine does have the burson upgrade but...). I still think it would be wise to check out the Topping model and if you don't 100% like the sound, 1st roll a few op-amps namely the Muses2 and the Burson discretes through it, then 2nd sell it off and buy whatever higher priced model you want. I'll even go a step further and offer both the Burson Classic and Vivid op-amps as a loan if you want to try them in the Topping D10. I'd offer the Muses but with the pin layout and no reverse insert protection I'd rather not be out $100. The burson models have reverse protection so I feel a little safer making the offer.
