SPL Tube Vitalizer

Esoteric EQ with two bands of compression
and output circuit with limiter tube.
the three lamps are Sovtek 12AX7 LPS.
all offer a nice finish, nice and rotating a good quality of VU meters, cooling and also well thought out and the rack just totally take place in environment "tight".

UTILIZATION

It is a machine that beautifies with fresh class every stereo signals.
Personally I use it live on or even master stereo bus, either on a classical music concert or a festival of jazz and contemporary music!!
Superb bus drums, vocals or strings .....
it is a machine with the indications can be a bit confusing, it is advisable to read the doc and then to validate what our ears hear,
It seems to me perfectly Qualibre for maximum versatility, if not a bit wide filter for my taste in "serious LC filter" / ON /.
by against the LC filter on the high is amazing, a lil bit and it was directly a beautiful color "English" on the top medium

SOUND QUALITY

I love the bass sound without bass soft mode "LC filter,"
LC filter or a mix of bland,
the medium filter mode is also open to the maximum of rare beauty,
even if the machine tends to dig a bit in the middle of the band, I love him Eq add a stereo out again just some areas of the medium
compression bands extreme high and low is effective and musical
this machine provides a nice sense of space and expansion of relief through the output circuit all lamps! the 12AX7 LPS with a high output level and collect more than any other 12AX7! (So ​​little distortion, but a beautiful harmonic generation)
It was actually thanks to a single machine able to perform work that would be complicated and usually require a more complex chain of hardware and high quality.

OVERALL OPINION

A serious and completely new machine in the world of audio,
as often with SPL, these are new and unique ways to approach the control signal. A kind of polar opposite to home TC Finalyzer!

I think it is necessary to combine the tube with a good vitalyzer Eq param stereo just have a real control on the medium that filters harmonic generation may tend to soften so too harsh.
Originality and quality of life really gives the signal.
excellent machine, rare and irreplaceable!

* Before I had an Avalon VT747sp for the same use that I finally sold the Tube Vitalyzer I combined today with a Neve EQ Summit Series "element 78" the MPE200, the medium is deadly serious as the extreme and upstream tubevitalyser the job done well!

I have mine on the two lamps kit of your choice (the original LPS) and currently 3x "OUR" matched United States in January!
their sound in the medium
