“Replaced the center 2 tubes in my Primaluna 400 integrated with these to see if they would really make a noticeable difference.After 70 hrs. I am definitely a believer.Lower bass ranges better defined.no noise.Highs and mid ranges are beautiful.A great inexpensive upgrade to an already fine amplifier.”

“Definitely a wider sound stage and cleaner top end. Also evident was a firmer more concise upper to mid bass region. Quite an improvement to the original trio in my Ayon Orion II amplifier. Extremely satisfied with these Brimars!”

“Great tube. Installed on PL Evo 400 Intergrated in the 2 center tubes positions. They took about 3 1/2 weeks to settle-in. They were a bit flat and dry in the beginning. They are hard not to like after break-in.”

“Just installed 4 of these in my Rogue RP-5. Dead quiet at idle. Absolutely liquid midrange, nice extension on the top end and excellent bottom end. Very happy!”
