I have Marshall SE100 speaker emulator that I attach to my Marshall 40W valve amp to play guitar directly with headphones. I use a pair of old AKG k240 at 600 ohm which are very flat. The only problem with that is the volume, as the headphones are 600 ohm the volume is low so I need an amplifier for them. I have seen these 3 models, any experience with them?
All three have the opportunity to input the signal from the audio board and resend it to speakers monitors which it's something I need to do.
