Tube Rolling | Tweaks | Music
 

Every LSA amplifier is given a 100% quality control inspection and upgraded ElectroHarmonix 6922 tubes - an excellent match for our amplifiers. That said, audio enthusiasts sometimes give as much personal attention to the tubes in their system as they might to an actual component. Hence, the practice of tube-rolling.

Before relaying some user preferences, we would like to convey that LSA Group reserves the right to deny warranty service on our amplifiers when internal modifications have been made. That is to say that, if by replacing the factory tubes the user causes direct or indirect damage to other parts of the amplifier, LSA is not obligated to repair the amplifier under warranty. Of course, we are happy to repair any of our products but, in such a case, the owner would be charged for parts and labor.

In the case that the factory tubes have been replaced with aftermarket tubes and an unrelated defect is discovered, LSA will perform the repair under warranty.

Finally, please know that the internal parts of our amplifiers can retain dangerous voltages even when they have been turned off and unplugged. LSA Group does not recommend performing any sort of internal modifications due to the possibility of personal harm by electric shock or, worse, damage to one of our fine amplifiers. ☺

That said, tube rolling is done every day. Here are some tubes that LSA amp owners have enjoyed:

Amprex 7308

Bugle Boy 6922 - described by our users as having a very 'lush' sound

EL6DJ8 - '...very sweet, good bottom end...'

Telefunkin 6922 (NOS)

Music

Jazz:

  • Diana Krall - almost all of her work can be charactarized as tasteful and easy to listen to and occasionally - as in 'When I Look in Your Eyes' - one has the aural sensation of listening from inside her mouth.

Blues:

  • Larry Carlton - Sapphire Blues, Last Nite (Live at the Baked Potato)
  • Mighty Sam McClain
  • Robben Ford - Perhaps the greatest guitarist alive or dead, Robben has collaborated with the Yellowjackets, Miles Davis, Greg Allman and Larry Carlton in addition to his own collection of recordings. Great tone, technique, and versatility make him the complete package.
 

Bluegrass/Counry:

  • Alison Krauss, Forget About It - Expect rich harmonies, unusual chord progressions and a myriad of well-recorded acoustic instruments.
  • Nickel Creek, Nickel Creek - the young, seasoned trio are each virtuosic instrumentalists, and their three-part harmonies are exceptional. This debut recording is intimate and inspiring.
 

Classical:

  • Firebird Suite, by Igor Stravinsky- R.R. Eiji Oue conducting the Minnesota Orchestra. This recording is clean, spacial and incredibly dynamic. Its more bombastic passages might occasionally reveal where John Williams got some of his inspiration for film score. The finale, featured in Disney's Fantasia 2000, begins with a simple flute melody and builds to a triumhpant frenzy of clanging triangles, uninhibited brass and subwoofer-destroying bass drum hits. Keep your fingers on the volume button, particularly if you live near a significant geologic fault line.
  • Nessun Dorma from Turandot, by Puccini - A signature piece in The Three Tenors collaboration, Luciano Pavarotti's performance of this emotional, physically demanding aria is super-human.
 

Choral:

  • Lux Aeterna, by Morten Lauridsen - Composed in 1997, this work has taken the choral community by storm. While his progressions are simple and palatable, this work is a study in chord inversion, added tones, and dissonances which only human voices can render so beautifully.
  • Vespers, by Sergei Rachmaninoff - "I know the voices of my countrymen," Sergei replied in defense of writing bass lines as low as B-flat (two octaves below middle-C). Under the direction of Robert Shaw, his Festival Singers create endless, breathless melodic strings. This more famous setting of the Eastern Orthodox All-Night Vigil is music to die to.

 

Folk:

  • David Wilcox - Currently on a one-man US tour with his family in an RV, Dave's rich baritone vocals, alternate acoustic guitar tunings and introspective lyrics create an easy setting for getting lost in the music.
 

Pop/Rock:

  • Carlos Santana, Shaman - This a relatively recent collaboration which includes such voices as Seal, Michelle Branch, Macy Gray and Placido Domingo. The number and variety of musicians on the recording make for a wonderfully complex soundstage, rich with percussion, pounding bass, and Carlos Santana's signature guitar riffs.
  • Joss Stone - the beautiful British teen has a voice that almost seems transplanted. She sings with soulful power that defies anything you might presume from her press photos.
 

Other:

  • Raul Midon - A one man show, Raul's soulful voice and innovative, percussive acoustic guitar playing set him apart from 'everyone else.'
 

Singer/Songwriter:

  • Lyle Lovett 'And His Large Band', 'Live in Texas', others - To listen to a Lyle Lovett album is to meander across genre lines from blues to folk, country to Texas swing, gospel to big band. He is a tongue-in-cheek cowboy in 'I Married Her Just Because She Looks Like You'; a childish misanthrope in 'If I Had a Boat'; a bitter ex in 'M-O-N-E-Y'; an emasculated spouse in 'She's No Lady, She's My Wife; a remorseful adulterer in 'Nobody Knows Me'; a mutinous parishioner in 'Let's Go Eat'; and 'I Go For Penguins' is simply enigmatic. The four-time Grammy winner is accompanied by a world class band, including a full horn section and gospel quartet, to back his rough brand of poetry. Music, lyrics and sonics are all unlikely to disappoint.
 

Labels:

  • First Impressions Music - Producer Winston Ma has created some of the most intimate, holographic jazz and classical recordings we've ever heard.
