I have been partnering the WvL Son speakers with an SA Lab Thunderbird SE (25wpc into 8ohms) in a large one room loft space (about 1500 sq ft) to what I at least feel is superb effect. My digital source, a Tron Atlantic DAC, has rather low gain into the modestly insensitive SA Lab input, and even still I have plenty of headroom.A friendly fellow visited me to hear my Zu Definitions 4 based system, and his positive experience means he's adding Druids 6 to a shortlist of spkrs he's considering, headed by Wolf Von Langa Son field coils.
The Zus are 101dB 16 Ohms, the Sons 95dB 8 Ohms. He will be listening in a standard living space maybe a little smaller than 18x12.
I've recommended the Bakoon 13R and 41R to him, 25W and 50W. He's also looking at the flagship Vinnie Rossi 100W DHT/SS hybrid. LTA 50W integrated and Pass Labs 45W on Icon Audio AVC also contenders.
Any thoughts especially on Bakoon powering the WVL Sons, or Zu Druids?
As such, I suspect the Bakoon 13r would be amply powerful for them.
