Apologies if this has been covered before, but I've spent the last hour or so searching the forum fruitlessly. Simply put, can a European-spec MZ-N910 be hacked to bypass the volume limiter? If so, how? I'm already using the excellent Sennheiser PX-200's and for most instances the maximum volume is sufficient, but I'm adult enough to decide the exact volume level I'd like without the European Parliament's bureaucratic interference. Ta! Rob
