I've had the above Sennheisers for nearly a decade now and I've never really had much need or love for them. To cut to the quick: now I'm looking for something better. Something that won't leave me completely disappointed when I compare them to listening to my speakers. I realise these are two very different ways of listening to music, but I find the switch to headphones (usual reasons: late at night, young family in bed etc), after I've had a few hours with the B&W's always feels unfulfilling. The obvious pairs that I've considered are the GS1000's and the similarly priced Sennheiser model. But do I really need to spend up to £1000 to get near to my B&W's? My headphone pre is a Musical Fidelity X-Can V8P. Rest of kit in sig below.
