Vacuum State has two locations - Australia/Joe Rasmussen and Switzerland/Allen Wright. The JLTI was originally manufactured in Australia by Joe. The first units (which is what I have) had point to point wiring. Later Australian units were on a circuit board. Production was then switched to Switzerland. The simple cosmetics of the Australian unit were replaced by the more elegant Swiss cosmetics. The external power supply was also added as an option.
I have compared my unit to a circuit board Australian unit. To my ears, and the owner of the circuit board unit, my unit sounded better. I have not heard one of the Swiss units. Jay at Audio Revelations has heard both my unit and the current Swiss made units, though not at the same time.
With regard to the external power supply, I have not heard the current Swiss unit. I know that Jay at Audio Revelations has done comparisons on the Swiss unit with and without the external power supply. He told me that with the external power supply you gain some things and lose others. Depending on your preferences you may or may not prefer the external power supply.
Jay has done more listening to the JLTI than anyone I know. Give him a call and he can give you the details.
However, with or without the external power supply, it is the concensus opinion of our extended listening group that the JLTI in any of its three forms (AU p-to-p, AU cb, or swiss) is a tremendous sounding unit that performs far above its price point.
