Hi Albert, sorry for the late reply. Yes, I did install a 105W supply in one of my 861's, and it sounded fantastic. Good as the G68/LPS is, the 861/LPS is clearly better. However, fitting the 105W supply was difficult. It may just have been a learning experience for me, but the space taken up by the capacitor board made it difficult to fit the LPS mountings. If you wanted to go that route, I would make very sure that its all going to work. In particular, its important to be able to install and remove all the electrical and mechanical interfaces with the PSU in its installed position. On the whole, I would recomend the CP498 for the 861; there's really not much wrong with that. If you fitted a CP498 you would be be very happy with it.

Regards, Nick
