The evolution of the original irreverent and irrelevant and non-authoritative site for headphone measurements, i.e. frequency response graphs, CSD waterfall plots, subjective gear reviews. Too objective for subjectivists; too subjective for objectivists

Desert ironwood looks awesome -- I think I am saying this phrase every year lol.. regardless, it's definitely another wood I desire to collect.

According to the Wood Database, this wood is as hard (3,260 janka lbf) and dense (75 lbs/ft3) as African Blackwood: https://www.wood-database.com/desert-ironwood/
(harder and denser than Cocobolo)

FR measurement (not Jude's but Zach's) looks interesting too. Not sure about which pads were on each. @zach915m may chime in.
If SBAF members are interested, @Zampotech said he can make a limited batch to sell here. I think he's shooting for somewhere around $250 + shipping, if I understood correctly.

I've spent a fair amount of time with this "Shortest Way" amp. I still have some comparison testing to do, especially with the ZDT Jr. but have enough thoughts to get started.

So, what is this thing?

- Single-ended, Triode, using 6Z51P tubes
- Output transformers (two types of steel to improve performance at a smaller size, would have to use regular, larger transformers if more are produced)
- Class A
- No capacitors in signal path. Really just a pot and a few resistors, that I can see, plus tubes and OPTs.
- "No feedback except natural communication through the cathode resistor"
- Short signal path
