rodizzleYes.
I’ve got the A30 Pro and the HE6SE V2 (Adorama version). I can get it painfully loud if needed; the amp puts out 3.4W at 50 ohms. Plenty unless you’re determined to go deaf.
rodizzleI've tested it with the he6se and it can get them loud enough with a Topping d10b DAC right up until you hit -4db preamp reduction to equalize them. At -6db like for an autoeq profile it runs out of volume on pre volume war recordings like the extended version of Tonight, tonight, tonight by Genesis and some Fleetwood Mac songs like The Chain.
The A90d has more power balanced to take it further.
