Tannoy Differences

Definition line is still made the UK.

The DC8t's are great speakers, but so are the Turnberrys. Tough call really, but if you don't mind the slightly higher cost, then I would go for the Turnberrys.

***Tannoy dealer disclaimer***

All I can say is that I love my Turnberrys and would only sell them to go the Kensington or above in the Prestige line, but I certainly don't feel any urgent need to do so. I think your XA60.5 would do fine with the Kensingtons, though. Although I didn't use it with these speakers I have owned the XA30.5 and did use the similarly powered Luxman M600A with them. Plenty of power. My room is 17x15 with a cathedral ceiling.

The Glenair (10 and 15) sounds more natural -- and a bit more resolving -- than the DC8T. I imagine the Turnberry would be similar to the Glenair 10. All are very nice speakers for the money. The DC8T has a lot of power available down low, and is a fun listen.

The Kensington SE and Yorkminster SE, with their pepperpot tweeter & alnico magnets, are both significantly more detailed than the Glenairs. The Yorkminster is significantly more efficient and notably more extended (in bass) than the Kensington. The Kensington is at least the equal of the Yorkminster in midrange & treble, and (IMO) much better looking. At 93dB/Watts for the Kensington/Turnberry, you're just on the cusp of high efficiency -- 95dB is where it really starts.

Not sure how much stok to put into these numbers, but from Tannoy they suggest:
Kensington 50-225 watts
Turnberry 30-180 watts
Glenair 10 50-200watts

I would think with only having 60 watts, the Turnberry are my only choice.

Gwng8, the Pass 60.5 should drive any of those speakers easily unless you listen at exceptionally loud levels in a large room. Typically a pure class A amplifier of 60 watts would be the equivalent of a 200 watt power amp. Of those recommended I would buy the Turnberry or if funds permit the Kensington which has the alnico magnets and is more resolving.
