A friend loaned me his Trafomatic Head One last night. YAY!
I didn't have all my gear with me and will post more impression with the GS1ki and RS2 soon.
I listened to them on two the HF2s. It's not a real test but was just a play. Sources were my ipod (EFN-made line out to RCA cable). Also tested them on a Playstation One (with JPS interconnects).
First Impressions:
Build quality was OK. It felt really sturdy and well made. Most parts were well made. However, there were some niggling production issues (mainly cosmetic).
The two gold knobs (the amp is similar to this one below) had the slightest bits of tarnish. Actually, there were spots on them. Not dissimilar to metal which has been left in a humid place for awhile. This amp was ordered from Trafomatic via a store in Singapore. It wasn't dead stock sitting for months on a shop floor.
The headphone jack and also the bottom right tube sockets were misaligned with the precut holes in the housing. The were slightly left of the holes. This again, was cosmetic and didn't affect functionality.
The image of the Head One differs from the current one on Trafomatic's website! Can anyone confirm if cosmetics have changed since the 6moons review?
Amp was burned in for 400+ hours on the stock tubes.
CD: Corrine Bailey Rae. The Sea. Tracks 1 (Are You Here) and 2 (I'd do it all again).
Straight out on the lowest 30ohms setting, the HF2s were a little boomy and bassy. The vocals were quite forward. The soundstage was small and felt quite cramped.
The 100ohms setting changed the sound signature. The vocals came forward a little more.
The 300ohms setting push the vocals back and made the soundstage a little more distant (but not wide).
This are just some preliminary observations. I am taking home my GS1ki and RS2s from the office today and will post more impressions soon!
