Hi, a raw, not absolute explanation: You can get cheap envy24 sound devices at Ebay, they provide +4dB and -10dB for the IOs. +4dB is used for professional audio and -10dB is consumer level. The phones output of your Laptop should work too, I suspect the audio engineers didn't like you or they had no knowledge how to fix the issue. Anyway, the sound quality of an Envy24 audio device will be much better than that of you Laptop's onboard device, epecially better than the output of the headphones amp. There are professional audio devices available, that do sound much, much, much better, but they are beyond your price limit. You could try to get an Art Tube Pre Amp, at Ebay too, this is prosumer, but also used by professionals. They are cheap and good.
