I am indeed hesitating now between the 2 amps: Apax or EDBA and I have hard time to convince me that the Apex is worth 2 tilmes the price of the EDBA.
- What Headphone & DAC will you be using ?
I've owned ECBA (only sold b/c I mainly run 'stats and I plan on getting a custom amp from EC in the future.) Under good meet conditions I was able to hear the EC 2A3 (with BA heater) running KenRad 45s situated right next to the Pinnacle running the Sophia PX4s. I don't remember the sources, but I think Craig was running his Hypermoth DAC, and something decent like a high-end Oppo was on the Pinnacle. A modified HD800 was used. I also had my BA (minor mods to run vintage PX25 tubes) at the meet, but in a different room.
In my opinion, the EC 2A3 (and my own BA at the meet) were better than the Pinnacle for a head-amp application. The most significant and obvious difference was the openness and spaciousness offered by the HF heater of the EC stuff. Other stuff like micro-dynamic rendering, speed were too close to call under meet conditions. I have a higher level of confidence that the BA edges out Pinnacle in micro-detail extraction, but again that's too close to call. The Pinnacle was probably a little cleaner sounding with more of a defined leading edge than the EC amps.
I too had the Pinnacle under consideration, but it seemed more of a sidestep, at least to me.
As an aside, the amp which most reminded me of the Pinnacle's presentation was the Manley NeoClassic 300B (I don't remember what settings were on that amp since its got all these tweaking options.)
