Argon MK3's Amp Question

Can I drive these with a Sennheiser GSX 1000?

Yes, but not as good as other amps in a similar price range

I would only suggest the gsx 1000 if you needed a mic in or really really wanted those dsp effects

I tried it with a t50rp mk3 pre-argon mod. It was under powered. Max volume resulted in just enough to hear music, but I wouldn’t use it with that amp.

Kinda what I would expect.

You can get a liquid spark + d10 for around the same price and be much better off

Or if you needed an option with a mic, if you can find one, the burson play would fit the bill
