Got matched pairs of Brimar, Radiotechnique and new production Gold Lions for do some rolling in the PS Audio BHK pre. One of the Brimar tubes arrived cracked but was promptly replaced by John at Team Upscale. Their support staff is excellent and respond very quickly to emails. I will have to report later how it goes.

The less than $200 cost of installing two Brimar 12AU7 tubes in my Rogue Audio RP-5 preamp has resulted in what sounds like a $2,000+ system upgrade. These “Brimar beauties” are better balanced and provide improved music detail than the very acceptable included tubes. My modest Revel f206 speakers now deliver more bass and lower mid-range response than I had thought possible. Overall, my system has an enhanced sonic quality that has made the Brimar 12AU7 tubes a great choice. It’s also important to note that Tamara and John set the standard for great customer service by expeditiously resolving an order processing snag.
