Rolling with Raytheon 6J5 Metal Cans 1957-13th week (March) with a Sylvania GB-6080 power tube.
My only comparison which I have been listening to for the past month is the Philco 6J5 Metal Cans. The biggest take away of these Raytheons is that they are more a mid-forward tube (as compared to the Philco's 6J5 Metal*possible Sylvania) The mids/vocals shine a bit more here - definitely more emphasized with these tubes. Nice overall dynamics and the sustain/decay of notes are very organic sounding -- meaning that hi-hat cymbals, guitar plucking is detailed and natural. The crashing and twanging sounds are where they should be! The upper registers are non-fatiguing and there is good separation and details. One simple test I always put it though is listening to Foo Fighters - Everlong - which has alot going on across the gamut. When turned up really loud, the guitar distortion work can sound sound grating really fast. But in this case, it remains cohesive and clear to really high volume levels and never gets fatiguing, yet can also pick out the background details concurrently (nice layering) - the subtle drum and cymbal work that still cuts through the front and center guitar work. Same with listening to Joe Bonnamassa (Blues Deluxe) - Pack It Up song. Guitar and drum work is a pleasure to hear with these tubes as it shines and has great detail. Bass is hefty/punchy but controlled. It does not lack in this area whatsoever. Another enjoyable pair of tubes.
This morning's test list:
Foo Fighters - Everlong
Joe Bonnamassa - Pack It Up
Jimi Hendrix - All Along the Watch Tower
Tom Petty - Free Falling
Audioslave - Jewel of the Summertime
Lupe Fiasco - Hip-Hop Saved My Life
Powerman 5000 - Danger is Go
Nine Inch Nails - Sanctified
Pink Floyd - Wish you were here
Ozomatli - Eva
Everything but the Girl - Missing
10000 Maniacs (MTV Unplugged) - These are days
Drowning Pool - Bodies
Red Hot Chilli Peppers - Snow
Wyclef Jean- Kiss the sky (accoustic)
Rush - La Villa Strangiato
Bach - Brandenburg Concerto No 5
Beethoven - Moonlight Sonata (Classical Guitar)
Is this a characteristic of Raytheon's house sound? If so, it is quickly becoming a favorite. I'm sure other tubes (maybe the shouldered glass types might be better and given a better sense of soundstage or details, etc), but the kicker....My total tube cost is around 10 dollars for the pair and is a very great bang for your buck that does so much right. Easily recommended if you come across them.
