Hi Rooze,
I contemplated purchasing the Phoebe II but instead bought another preamplifier in 2014 for a good deal. It took a long time to develop these products. I'm assuming the Son of Ampzilla II will be in the same class as their previous version. Wyred 4 Sound bought the company from JB before he passed away.
Cheers Rod
ps. the Ambrosia now cost $12000AUD here in Australia. The aussie dollar has fallen quite a bit compared with the USD. No hifi purchases at the moment.
