That's all very impressive and all, but let's be frank, who needs 16W into 16 Ohms? Even 6W is too much. On the other hand, this is yet another Extremely clean, powerful Amp into Low impedances, but rather underwhelming into High Impedances in SE mode. 165W into 600 Ohms is less than a quarter of the stated 670 mW in Balanced mode, and hardly impressive. Ditto for the 300 Ohm figures. Heck, my Violectric V100 debits 640 mW into 600 Ohms and over 1W into 300 Ohms, all of it through a 6.3mm Jack!
6000mW x 2 @16 Ohms THD+N<0.1%
3000mW x 2 @32 Ohms THD+N<0.1%
1550mW x 2 @64 Ohms THD+N<0.1%
330mW x 2 @300 Ohms THD+N<0.1%
165mW x 2 @600 Ohms THD+N<0.1%
17000mW x 2 @16 Ohms THD+N<0.1%
12600mW x 2 @32 Ohms THD+N<0.1%
6000mW x 2 @64 Ohms THD+N<0.1%
1370mW x 2 @300 Ohms THD+N<0.1%
670mW x 2 @600 Ohms THD+N<0.1%
16W is only possible in balanced operation in 16ohm.
16W into your low imp IEM, by accident when lying on a table, will destroy it in milliseconds.
I keep hoping for a Modern, State of the Art Headphones amplifier at the right price (I thought the A30 Pro was it ), preferably Remote Controlled, that ticks all the boxes, but sadly this isn't it yet...
