Hi all, I'm fortunate to own a pair of Grade 325e and Santa is bringing me a Schitt DAC (Modi 3) and amp (Magni 3) for Christmas, however, my stocking is not yet full.... ;@) My wife and I share an office space and she's not too happy about the leaky Grados. So... I'm in the market for a pair of closed back headphones. I use some AKG 52s at work which are OK (more than OK for £39!) but I'm after something better as my 2nd choice for at home for when I'm not disturbing the other half. Sony MDRV6s (or the 7506) have peaked my interest but I'm not adverse to spending more so interested in recommendations - bearing in mind the 325s are my current benchmark. Also interested to know if closed backs are simply not worth spending a lot on because they'll never come near open back? I'm also not adverse to finding some closed backs that beat the 325s and just consolidating to a single pair of headphones. Recommendations?
