Be nice if they squeezed line inputs into the DX3Pro+. I do like the size of the unit though. And the wall wart is reasonably sized unlike the huge L50. BTW, the K7 is updated to include BT. Kinda gives it the edge over the DX3Pro now I think.
yes.
DX3pro+ can drive even AKG K1000, as long as you can live with about 95dB maximum SPL. Enough as a recommendation?
XS’s are much easier to drive.No sonic advantage, but in some measurements fixed modes may give better results than pre-amp modes, where signal doesn’t go straight from DAC but passes through amp section as well. dx3pro+ has digital pot.
That's cool. No reason to use DAC mode in my case then. I'm pleased with the TV sound via toslink too. Nice to adjust volume with the remote. I have an old school line stage with no remote.DX3pro+ can drive even AKG K1000, as long as you can live with about 95dB maximum SPL. Enough as a recommendation?
I used to pair dx3pro+ with L50, and on my headphones (k612pro 101db\V, dt150 103db/V) there was completely nothing better with this L50 amp-beast;-) are you planning to buy something like HE-6 in future? If not, dx3pro+ should never be a limitation.

My headphone and IEM is nothing to write about but will eventually upgrade to some low cost Hifiman.DX3pro+ can drive even AKG K1000, as long as you can live with about 95dB maximum SPL. Enough as a recommendation?

I think the HFM Deva Pro looks interesting at a nice price. Designed for portable use too with a BT option. I imagine they don't need tons of power.
I do not know your system but ground loop very often is caused by the user, by too many or not enough groundings in the system, and one of the reasons may be using cheap, not proper balanced cables or power supplies. Noises from usb can be filtered out by various adapters, iFi for example has such in their offer.
Balanced out to headphones won't help with a ground loop (since the headphones have no connection back to ground to form part of the loop.
Appreciate the eagerness to help. I have no problems with ground loop yet. But prefer not to have a problem rather than troubleshoot one.
well, yes - many people have been saying the same.
I think that 45dB is believable. I have a relatively quiet office and still it measures around 20~30DB with an Iphone app. When I use the speakers I normally keep them under 80 and I don't notice the ambient background unless the AC kicks in.
Rated as 18Ohm, in practice measurements say these headphones are more like 15ohm. So you are pushing DX3pro+ into the region which is barely usable. If you want to listen that loud, with voltage output close to 2V, you need amplifier which will not be current limited with such low impedance. Or switch to headphones with at least 20ohm impedance, results will be much better with dx3pro+.
So, any suggestions for an amp?
Cheap and superb with stock power supply - Topping L30II.
