The only real point of objection is the safety stuff, the high risk of something really going wrong here. Pretending touch safety with a 3-prong connector and metal chassis is really the worst thing you can do.
Want to send those cables to Amir for testing so we can get more pictures of the headless panther?
This may be the very definition of damning with faint praise...but also probably not going to hurt anyone
@amirm any chance you could post those measurements?@amirm it would be great if you could post them.
One of the usual objections raised is that these devices are never run at full volume so measurements done at full volume are irrelevant.
The claim is always that the measurements would be much better at lower levels. These claims are of course, never backed up by measurements, so it would be good if you could post them and put that myth to bed
I did post the SNR at two volume levels/positions:@amirm it would be great if you could post them.

Wait a minute this is June 1st not April 1st ?
Thought it was a joke when I saw it.
Looks like a poorly made home brew preamp.
Note the input and volume knobs are not at the same height.
Why a switchmode power supply in a low current app like a preamp?

I was surprised that crosstalk was not frequency sensitive and not that good:
Seems like there is some coupling on purpose between the channels??? Strange.
I wonder why someone would make the decision to buy this at all. It’s not like there‘s some nice marketing page for it http://www.thehornshoppe.com/the_truth_pre_amp.html
"The Truth has a balance control that is not in circuit and the balance does not shift with volume changes ." This is patently false.
That's how I see as well now you've pointed it out.Looking at the device it is clear that the volume control is effected as an LDR in series with one leg of the balance potentiometer, with the wiper of the potentiometer grounded. The other channel is the same with its LDR going to the other leg of the balance potentiometer.

Varying either the pot or the light on the LDR will change the output volume.
No. The only common point is the ground.Does this explain the high channel crosstalk?
