some impressions.
* the Pinnacle is a beast of an amp. i spent a few hours listening to it with the HD800 and LCD2. the amp sounded great with both headphones but better with the LCD2. the sound was crystal clear with a slightly upfront presentation and very wide (L to R) sound stage. i can't say it sounded better than my BA (also PX4/6SN7) but without being side by side, it is hard to say. i briefly tried the HE-6 on the amp and the headphone seemed underpowered. in terms of build quality and looks, the Pinnacle is top notch.
* the Lyr/LCD2 definitely wins for best high-end sound on a budget. the Lyr has great synergy with the LCD2 and powers it effortlessly.
* i briefly compared the O2 MK1 and O2 MK2 on a Stax 717. i did not hear much difference between the two. the only thing i did conclude is that the 717 is a great amp for O2. if you cannot afford one of the better Stax amps, the 717 is the one to get.
* Kerry built a dynamic amp for a few hundred dollars in parts which made the HD800s sound fantastic. the DAC was an Opus. very nice combo. he does good work.
* i listened to the RWA gear. they have a new amp for the LCD2, which sounded nice.
i spent a lot of my time on the Pinnacle or talking -- a good time overall. well worth the trip.
