I did like the AMT3SE for my RAAL SR1a. I only used it for those headphones since I preferred my other 2 DACs on the floorstanders. The guy that created my Convolution files for my floorstanders just created Convolution files specifically for the RAAL SR1a ($250). SR1a owners are really loving these filters.

Once those were installed on ROON and run the AMT3SE became redundant. I liked my other 2 DACs more on the SR1a. I sold the AMT3SE in about an hour with many offers to buy. A very popular DAC.
