Echoing the thoughts of others above, maybe you should look into studio monitors. They do sound the closest to headphones. I have a pair of Equator D5 which I hardly use (going to put them up for sale soon actually). I plugged them in today and A/B'd the 1959 SLP preset with the K8. The D5's actually have more bass, but the sound is more integrated since the tweeter is in the same speaker as the woofer. Personally I still prefer the sound from the K8 but if you want really low volume single source sound, perhaps you will enjoy the D5 more. BTW if you had the K8 for less than 45 days, you should consider returning it if you don't like it... that's why we buy things from GC.
