Selling PH SR5 Turbo. Original owner. As new condition. Unit's DC voltage is switchable:

Rail 1: 19v (2.5A) or 15v (2.5A) or 12v (2A) or 9V (1.5A)

Rail 2: 16.5v (2.5A) or 15v (2.5A) or 12v (2A) or 9v (1.5A)

The Turbo upgrade adds a low power voltage regulator, powering the error amplifier/output stage driver resulting in better overall regulation, better transient response/settling time, and lower dynamic and static noise. 

This turbo upgrade is not exactly the same as the DR configuration used in Paul Hynes SR7 custom-builds, as the DR configuration uses two high power voltage regulators in series. However, the Turbo upgrade moves the performance SR5 closer to the performance of the standard SR7 PHD Ltd products.

According to Audiobacon reviewer, the turbo upgrade does sound quite a bit different than the non-turbo versions. It has a similar ability to realistically 3D mold the music like the Sean Jacobs DC4 and SR7. But it’s not quite as expressive or faithful but is still impressive for the price. The turbo power has decent texture and air. Treble is tuneful and has adequate shine. The midrange has plenty of clarity and resolution. It’s dense, but a little glossy. Bass has decent volume and momentum but is more even even-keeled than forceful. Where it shines is in representing textural cues and opening up the soundstage. Imaging is spot on and everything flows with variability in density.
