Red Wine Audio Isabella LFP-V Preamp

This listing is for a rare opportunity to own a Vinnie Rossi Isabella LFP-V edition LiFePo4 (Lithium Iron Phosphate) battery powered tube stage preamp. I am the original owner. The unit is in mint shape. I also have a matching pair of Vinnie Rossi LFP-V 70.2 monoblocs for an additional $1,750 as well if you are interested in a full system ($2,800), see photos, contact me. The small footprint when all three units are stacked is great if you have limited space. Sound quality is amazing for a system at this price. To sweeten the deal, I will pay for shipping anywhere in the Continental US if you purchase all three units at asking price.

I purchased this unit in 2012 same time I upgraded the 70.2’s to LFP-V tube stage. I am including a pair of JJ E88CC tubes, I never really used these tubes, so they are as new when I got them. I had Vinnie Rossi replace the LifPro4 batteries back in 2019, as I had been using the system in my office for background music while I worked. Then in 2021 I purchased another system and have not used these since then, so the batteries, tubes and electronics are in excellent condition.

There is a gain switch in the back for when you want to a 12db boost to play LP’s or for other reasons that you want an additional 12db gain, it also steps the volume control through more of a refined level of attenuation and does add that extra gain, so you get quite a bit of subtle volume change as you spin the control. The original remote control that came with the unit is included. The charger for this unit is the one all the way to the right in the photo.

This preamp is amazing as it is completely removed from AC power, and runs 100% on LiFePo4 batteries that Red Wine is known for, which last for around 8 hours, and if the batteries run low, an AC/DC switch in the rear of all units keep the system going. There is no need to purchase expensive power cables or conditioners as this unit is so sweet sounding off the grid, it’s amazing.
