Hello Nisbeth,
I was looking for information on Angstrom's headphone amplifier and I ran into this forum. For transparency's sake I need to say that I just ordered Angstrom's Stella integrated amp after comparing it sonically with other amps... but that's another story. I would like to address some of your remarks as I believe they don't make a good service to interested music lovers.
1. As I believe you are aware of, many hi-end valve amplifiers are point-to-point wired. Angstrom amps are no exception. In this case military grade teflon-insulated wires of the highest quality are used, that is a virtue when compared to PCB tracks, not a vice. Besides, the time it takes to masterfully solder and organize cabling is not comparable to a machine-populated PCB, hence a partial justification for the higher cost. About the use of perforated boards as support, I find that to be a brilliant idea because of its simplicity and I wonder why other manufacturer didn't think of it. I honestly find it impossible to look inside an Angstrom machine and say that it looks cheap, on the contrary i believe it looks outstanding.
2. Given that you commented on the plywood, let me address your criticism there, but it would be enough to look at the list of chosen components (e.g. Vishay) to quickly come to the conclusion that we are not in 100$ territory. Back to the plywood issue, two considerations:
i. Using plywood is a sound choice from a functional point of view. Compared to a solid slab of wood, ply provides increased mechanical resistance, it's not prone to bending as natural wood is, and (to my eyes at least) provides a more aesthetically pleasing profile (cut)
ii. Not all plywoods are born equal. Upon enquiring Angstrom's designer I was informed that the inner layers of side panels are made of birch whilst the outer veneer is made out of Italian olive tree. The finishing and painting is made at a local artisan's shop owned by a lutist. I also learnt that the top cover is cnc machined according to Angstrom's specification and painted in an oven like a car's bodywork. All of that adds to the price of the product, I challenge you to come up with an enclosure like that for 100$.
3. This comment addresses remarks from other posts in this thread but I write here for convenience:
i. as far as I know there is no trace of opAmps in Angstrom's designs, and the headphone amp is no exception
ii. At the Indulgence audio show in London just a couple of weeks ago this amp was driving Audizee and HiFiMan headphones without breaking a sweat. Glorious sound with the volume knob that couldn't be turned past one third of the full scale without causing permanent damage to the eardrum. I learned that the Stella Mk2 outputs 15W, no wonder driving the headphones was a non-issue.
Ultimately, 14K$ is an awful lot of money and the manufacturer has certainly a hefty profit margin, but that's audiophile's world. You can also find headphone amplifiers that cost multiples of Angstrom's and we all know that the rule of diminishing returns applies. Having said that, if one has the passion and the money I think Angstrom is well worth considering because of its design, craftsmanship, sonic performance and niche clientele. Certainly not in the category of "value" products, but a fair proposition in the premium segment.
Always enjoy the music,
Algaeuer

@Dillan: did you get the amplifier? Your feedback?
