The verdict

The 1255L makes sense only when its omission is understood. It has four valves in a professional-style 3+1 arrangement, the same 15.5-to-16.2 mm bore progression and 290 mm bell dimensions as the M5000, and an ergonomic 4.3 kg build—but no automatic compensating tubing. Miraphone explicitly positions it for players who prefer that.

I classify it as advanced because it is a specialized full-size instrument rather than a conventional intermediate step. The M5000 adds compensation to closely related dimensions; buyers should compare the response and low-register behavior directly instead of assuming the fourth valve makes the two functionally equivalent.

Who it's for
Advanced players who knowingly favor the freer or simpler feel of a non-compensating instrument but still want left-hand fourth-valve ergonomics and substantial German construction.
Known for
Easy response, good intonation, a 15.5-to-16.2 mm conical bore, 4.3 kg weight, gold-brass leadpipe, and an uncommon non-compensating 3+1 layout.
Watch out
Its professional-looking layout is not compensating. Combined-valve low notes still require player correction, so it is a specialist preference rather than a lower-priced M5000.
