I use phones and nearfield powered bi-amp speakers about equally. In the evening the 'phones are used more, but in the daytime the speakers are preferred.

The speakers are Yamaha MSP5A; 'phones are Sennheiser HD 340 (long discontinued - pity).

With my elderly ears, the sounds from both are surprisingly similar, so I use them interchangeably.
