I am looking at my first tube amp. It delivers 40 wpc
class A. I own an inefficient pair of A/D/S 810 speakers.
Will I have problems with this amp driving these speakers ?

The ADS L810 is a three-way acoustic-suspension
speaker (1981). This is an efficient 6 ohm speaker
(94 dB SPL/W/m) with a power rating of 100 watts,
200 watt peak. 40 watts of tube power should be
sufficient for a normal sized room unless you play
your music at excessively loud levels.

Perhaps if the room is small or very live.

You just don't know what you're talking about. I've filled large rooms
(in terms of "normal sized" listening rooms - not necessarily ballroom
sized rooms) using 35 wpc amps quite easily.

If the L810s have 94 dB/w sensitivity, they would be exceptional as most
ADS products run in the more typical 88 to 91 dB/w range.

As well as exceptional for acoustic suspension designs.
