Resistors placed in-line (as per original post). I tried 10, 15, 22, and 47 Ohm resistors. Add 5 Ohms to get approximate total DC resistance with each set.

The 10 and 15 Ohm resistors were still laid back and relaxed with plenty of bass, as mentioned above. This is a very addicting sound. Sweetness. The transient response (articulation) was still very fast, and should not be impacted by the change of resistors. The sound is like a hot-fudge sundae. Mmmmmmmm......

If not for remembering the 'Ety' sig, I likely would have left it at that.

At 22 Ohms (27 Ohms total) the "Ety" sound became a touch more apparent. A bit more high freq energy. Seemed like a nicely balanced response for most music. I enjoyed the time I spent at this setting. Everything sounded good.

At 47 Ohms added (~52 total) the "Ety" sig became more apparent. Kinda like turning up the presence control. Breathing was more apparent with an upper end 'hhhhhh', if you know what I mean, as were fingers sliding down the neck of a guitar. Piano had that extra little high freq 'air'. These sounds were there before, but not with the high freq presence they now displayed. Stand up and take notice, but without dwarfing the bass. Definitely a sherbet. Veryyyy nice for a hot summer's day.

The price of this leading edge 'definition' loved so much by Etyolics (myself included) was a slight decrease in the round, 3D like dimension of some vocals, such as the chestiness of tenors was diminished from before. All this is very variable and depends more on the recording itself than the style of music. That said, simple vocals vs complex orchestral works or rock bomb-basts handled it differently. Poorly recorded, etchy music was all the more so.
