Fyne 704 to replace A5s?

[ggdudeabides]

The A5s start flagging at about 95 dbs.

Please explain what "flagging" is. Room distortion at a certain volume level / certain music type? Amp maxed out and distoting? Magicos being pushed too far, speaker distortion and / or poor placement, music source? Room. amp, speakers, source or a combination (hope not) causing issue? Once you determine, can narrow down options to pursue. Could be as simple as speaker placement. As usual, Mr. Peabody and Michael's HiFi providing constructive input. Best
