For many years we have been refining a 4- tube circuit (2 tubes if line stage only). We have had many long debates about whether we should market it, as its a departure from our normal stuff; its single-ended (which is the big deal) and is more conventional circuitry. It uses a pair of 6SN7s for the line section and a pair of 12AT7s for the phono section.

However its also a very nice sounding unit, and we've seen it easily take on preamps that cost several times more with no worries. We've had a prototype that we have been playing here at Atma-Sphere for the last 3 years; we know this preamp very well and it really does do the job!

It has a welded chassis, 4 inputs and isn't very big. So far the plan is that they are entirely hand-wired and that has been working quite well. It has vintage styling, but not like our other products. Actually it is the first of a new lineup of amps and preamps.

With the Stepup transformers it works with low output moving coil cartridges and will retail for $2800.00. Without the SUTs, it works with high output cartridges and is $2400.00. Finally, it is available as a line stage for $1900.00. We expect to ship the first units in August.

Hi Ralph:

Right up my alley. I am throwing my hat in the ring for a review sample when available..:) These are the type of components I love.

Best of luck with it Ralph! I look forward to hearing it.

Great price points and if it sounds like Atmasphere gear, it should be a home run!!

That is great news Brian.

Brian is one of the good guys out there, a true gentleman.

Kudos to the team at Atma Sphere for making such a great looking product at this price point.:D

There are so many differently flavored 6sn7s out in the wild (and at affordable prices too!) that over here there is a sub-culture for single pair 6sn7 pres. It's a tube rollers dream.

Congratulations on the very positive RMAF reports Ralph. Keep it up!

A number of dealers were unhappy with the blue finish. So we updated the UV-1 slightly- now its black. UV1.jpg

On my screen this photo is not a whole lot smaller than the preamp itself.

We've been getting good comments- one customer replaced his ARC Ref3 line stage with a UV-1- he says it is better in every way. Another found that it was quieter and sounded as good as his Allnic L3000.

Some people don't like the purple lens- there are a number of colors available- red, amber, green, blue... and purple :)
