Hi,
T-Zero+ efficiency is 87
T1+ efficiency is 88
T1+ is recommended to have an amp with more watt output than T-zero+. Why?
Also, how is either of these with TA-100? Does TA-100 count as 90w / channel because it's 4 ohms (when T1+ has 75-350w recommended)?

The T1+ power handling capability is greater, and with that extra power it can "play louder" than the T-zero+.
That recommendation takes into account the ability of the T1+ to play louder with its increased power handling capability.

Only Emo knows for sure, but in general over the years in and out of the business (techie, not sales, usually) I have found that the power ratings tend to lean toward the top end, i.e. how much the speaker can handle, with minimum rating based on anticipated listening levels at a nominal distance. Thus a higher-sensitivity "larger" speaker may have greater power rating because it can handle more power. Note the difference between 88 and 87 dB/W/m is only a small difference in practice... There may also be considerations about frequency range and impedance over that range. |

Anecdotal observation, I had a pair of speakers that were 85db sensitivity and was running them with an Emotiva A-500 (110 wpc) and replaced that amp with a XPA-5 300wpc amp and the system sounded much better.
