Soundlumia's Opinion
Our best seller is back in stock - the Amperex USA 6922 PQ White Print! We have recommended PQ's to more than 20 wonderful patrons of Soundlumia eBay store around the world, who are enjoying the superb PQ sound in their class leading amplifiers from Audio Research, Ear, Schiit Audio and Cavalli etc.
Among all the PQ tubes, the USA white print version (made in Hicksville, New York) is the most sought after by serious audiophiles and tube enthusiasts. They are as sweet and smooth as the Amperex Holland PQ tubes, with even better detail and very spacious sound stage, which offers an amazing bird's eye view of the shape of your sound, so you know exactly how tall and wide the sound stage is. The tone is warm yet lively, mids are forward but also expansive like what you hear on their cousins from the Holland factory, bass is punchy but not heavy. We have recommended them to so many satisfied customers that we have given them a nick name "sound purifier" - the sound that comes from these tubes has absolutely no edginess, glassiness or harshness, and you hear nothing but the soul of your music and all of it. They are the best tubes to to put in the phono stage to "purify" your sound in my opinion. As to vocals, I have no further comment than that the best Mullards were actually sourced from Holland PQ's (Made in Gt. Britain w/ Heerlen date codes) and USA PQ's beat the Holland ones in vocals period. Listening to Righteous Brothers' Unchained Melody through these PQ tubes should be on your bucket list, no matter what type of music you enjoy.
