Hi there, first time poster here!
I've been lurking around for now and then and finally it's time to start posting. I know there is another thread about headphones, but I have more specific questions and didn't want to intervene that thread.
I'm using a Yamaha DGX-650 with AKG K242 HD. It's working fine, even though I think the max volume is a bit lower than I would have wanted.
I'm thinking about buying a new pair of headphones, either Sennheiser HD 598, HD 600 or HD 650.
1. For the 600/650, the impedance is massive 300 ohm. Would that lower my volume significantly?
2. If possible, I would like to avoid a separate headphone amp (additional space and power connector), so maybe the 598 is a better choice in that regard. But would the 600/650 be a much better choice of headphones for a digital piano? I'm buying long term here and money is not an issue here between 598/600/650.
3. If I would buy a fairly small headphone amp, are there any recommendations for this specific purpose?
4. I'm going to buy a new piano fairly soon, and two of the likely candidates are the Yamaha CLP-575/585. Would the volume for headphones be similar to what I'm experiencing on my DGX-650, or can I expect a better output volume there?
Other suggestions would be most welcome. Thanks for reading.
