Balanced Tube Preamps I Should Try

Audio Research LS-25Mk II, Fully Balanced and tube hy-brid

You should look at a used BAT VK50SE. I have seen them on this site for around $4000.00. I have owned mine for about three years and is the only piece I have not sold off for something else. The 50SE is upgradable if you decide to do so in the future. One of the very best sounding pre amps out there bar none!!! Good luck

Swampwalker - The Supratek XLR outputs are balanced, meaning each XLR output transmits two phase signals. But the preamp is not considered a balanced design.

I'll second the Sonic Frontier Line 3 in "regular" or "Special Edition". Excellent preamp, fully balanced, great remote, HT throughput (if that's important to you), and very well made. Retail from $5k + , used Agon from $2.5k + .

There is a VAC Renaissance for sale right now. It is a true differential balanced input and output. Each input is selectable for single ended or balanced with a toggle switch. The balanced inputs can be utilized even if the source is not a true balanced output. The remote control has volume, mute, and source utilizing motorized switches. If you are tired of hiss and hum and want dead quiet this preamp is for you. The build quality is outstanding plus it's a very eye catching piece. Check the review in Stereophile of the Signature version as I feel it applies equally to the standard version. When I purchased mine, I was expecting maybe something like a 20% improvement over my previous Audio Research preamp but I got like 100% better. This is an outstanding preamp.
