i've got 2 pairs of AP2s and a pair of AP3s here at the moment- i think i saw the above praise for the AP2s on here and found a pair. Unfortunately, they all seemed to need re-foaming and then i found another pair of AP2s which didn't look as if they needed re-foaming but in fact they did
Hence 2 pairs.
The Ap3s are the same as the '2s except for slightly deeper bass.
Think i prefer Heybrook HB1s , which are mechanicaly very similar but the AP2/3s are good. One pair are a late pair in black ash with biwire terminals but are linked internally and the earlier pair are single wire and have active speaker terminals, which bypasses the internal crossover.
The Ap3s are late and are proper biwire. The Ap3s were £300 and the '2s were £250 and both received good reviews at the time. They use Vifa drive units.
Those Sonatas look a heck of a lot like Mordaunt Short MS15s (of about 15-18 years)
