I’ve been comparing my headphones to my full range floor standing speakers. Two different pairs of headphones:
Sony 7506 ( Very bright to my ears) and Sennheiser HD 650’s
Speakers: IMF Studio TLS 50 floor standing transmission lines.
To my surprise the IMF’s sound virtually identical from top to bottom compared to the Sennheisers.
I’m feeling really good about my 50 year old IMF’s! I’ve had them since new and rebuilt the crossovers a few years ago with ESR equivalent capacitors from the UK and replaced the midranges with Monocor drivers and tweeters with Audax drivers. Sound like they did when new. What Im taking from this is that for a set of loudspeakers in a room to compare to a top flight pair of headphones shows that the speakers in my listening room are top performers.
Thoughts?
