First, to calculate the power required for your 95dB speakers for an 85dB normal listening level, your calculations may (or may not) have to be adjusted as the 95dB spec is based on (a) 1m listening distance, (b) one speaker and (c) no wall boundary reinforcement.
(a) Each doubling of 1m listening distance will decrease output ~ -6dB
(b) 2 speakers will have ~ +3dB greater output than a single speaker
(c) Wall boundary reinforcement could be from ~ +3dB when placed next to walls to ~ +6dB when placed in corners, depending on distance.
In the end, if it still calculates to 1/8W for 85dB output for your particular listening distance and speaker placement, 16 times the power (2W) would give you the capability of 12dB peaks. Depending on the music you're listening to, it may have as little as 6dB peaks for highly compressed music and could have possibly as much as 25dB peaks for uncompressed high dynamic range music.
A 4W amp would allow another 3dB, or 15dB total peak. A 12.5W amp would allow 20dB peaks and a 40W amp would allow 25dB peaks.

Hi Steve and all Audio Circle members.
Thanks a lot, that's super good information,
I was not expecting so much useful information,
but since it's there,
I will take it with pleasure.
With your information,
I will do some calculations with the dimensions if my room,
placement of the speakers in relation to the walls
and listening distance from my speakers
and see what I will come up with.
I will get back to you with some results.
Thanks again.

P.S.
Audio Circle is the top of the top when it comes
to get good information.
