I bought this little unit in about 2012 from a dealer (it was a demo unit, I am the original owner) to be able to use both moving magnet and moving coil cartridges. It has jumpers to adjust both gain and loading. If I can find the package of jumpers I bought, I will include a few extras in with this phono stage (the little buggers are easy to lose). This is the version manufactured by Vacuum State in Switzerland comes with the manual and the original wall wart power supply, I do not have the original box. When it was released it got lots of rave reviews. Below is an excerpt from the Positive Feedback review in 2014 or so. Moving magnet gain is around 40 dB and moving coil is around 58 dB (rated at 55). The phono stage worked just fine with my 0.24 mV ZYX. There are some marks on the top where I had some additional weight added for better isolation, otherwise in excellent condition. Some remarks from the manual (see images): No opamps in signal path, state of the art low noise, extreme channel matching, high and low gain, 470 and 47K ohm loading, hand built in Switzerland. If you look at the image of the manual you can see more detail on this, and that they derived their specs from actual production units. These originally retailed for about $1,800 over ten years ago, I have no idea what they sell for now, so offers are welcome. A note about shipping. Since it is very difficult to accurately estimate shipping to all locations in advance, I list the maximum amount that a buyer would pay. If shipping is less, I refund the over payment as soon as I have printed a shipping label. Images are part of the description. OFFERS WELCOME!!! Questions welcome too. Thanks for looking, Mark Among the best values currently available in MM-MC phono preamps. Michael Fremer, Stereophile. Stereophile Recommended Component - October 2011 The Vacuum State JLTi PhonoPre is among the best values currently available in MM-MC phono preamps, particularly at $1650... it came remarkably close to revealing the long, long reverb trails on those great records we all know and love, and its retrieval of low-level detail and micro-dynamics were particularly impressive... Adding the outboard power supply took the JLTis performance up a few notches, particularly in terms of the all-important rhythmic grip and the preamps ability to deliver musical meaning. - Michael Fremer, StereophileOut of the box, I was surprised at how good the JLTi sounded. It really did not sound like a solid stage phono stage, it had more of a very well designed tube phono stage sound. In comparison to my Herron tube/hybrid phono stage, which cost almost three times as much, the JLTi held its own. With the JLTi the music arose from a blacker background, bass was stronger and more forceful, and it had a wide expansive soundstage. Where it feel short of the Herron was in the creation of three dimensional images within the soundstage. Producing 3-D images is something that tube phono stages excel at and with which solid state amps usually have trouble. The Herron was also slightly more musical and had a greater sense of ease. For classical music or small ensembles, the Herron is my preferred phono stage. However, for heavy metal and soundtracks created on synthesizers, I prefer the JLTi. This is because its weaknesses are not important—who listens for an expansive soundstage or 3-D imaging on a heavy metal LP—and its strong point, excellent, forceful bass is what the music needs. After a few days of listening to the JLTi a reality check was in order. Was the modestly priced JLTi really that good? Did it really offer that much bang for the buck? To see if my ears needed to be realigned or not, I arranged a phono stage shootout at a friends house, Jay Kaufman of Audio Revelation. Jay sells out of his home, but how many brick and mortar stores do you know that have twelve different turntables on display from seven different manufacturers? On the arranged day, Jay, two audiophile friends and I listened to a Brinkmann Balance turntable with Graham Phantom tonearm and Shelter 90X cartridge, through an Airtight ATC-2 preamp, Airtight ATM-2 amp, and Avalon Opus Ceramique speakers. The different phono stages with which we compared the JLTi included the ASR Basis Executive, the E.A.R. 88PB, the E.A.R. 324, the Art Audio Vinyl-1, the Whest, the Eastern Electric MiniMax, and the $300 Firestone Korora. By doing A/B comparisons with the same LP track, we arrived at a consensus about the relative ranking of the phono stages. The JLTi was preferred over the Art Audio, Whest, Eastern Electric, and the Firestone. Against the ASR and the two E.A.R. phono stages the consensus was that while the four phone stages were different, there was no clear cut winner. They sounded different, but which was the best was a more a matter of preference than anything else. At this point I told my friends what I had paid for my unit. Their jaws dropped. The aftermath of this listening session was that one of my audiophile friends purchased the last JLTi Mk I and my other friend purchased the first JLTi Mk II to come off the production line. Jay became the USA agent for the JLTi phono stage.
