Thanks so far Tony to answer your points. I have used many valve amplifiers in the past and want to now stay with solid state. Either keep my Ayre MXRs (which I know for sure would go well with K2 or Westminster) or move to low power Valvet (25 watt monos) still using my Wadia 27ix as a dac and not as a pre-amp. I know I would need to buy a pre (thinking Mac C46) as I want to have TV/blu-ray through the system as well. Room is 13ft x 19ft. I digital stream my music so I have no cd player but have 2000cds on hard drive accessed via Mac Book Pro into the Wadia 27ix dac. Music is in the main ambient (Brian Eno et al), World Music, Bob Dylan, David Sylvian, Classical, Opera and many movie soundtracks. Hope helps.
