I hear they're addressing it - all they need to do really is strap on a tube ring,

or maybe get some better damping material between the chassis and the tube

 

Haven't tapped to check it out yet,

but it sure sounds DAMN good thus far...


The microphonics come from inside the tubes, so there's not much that can be done about it. Another user here tried putting rings onto the tube but that didn't help the microphonics at all.

RELLY - 

hmmmm

 

perhaps the socket???

Choice of tube???

I'm gonna write Jason and the gang and figure this out.

 

I haven't experienced any microphonics yet - but then again I haven't tapped on it.

The first thing I did when I got the vali was to open the amp and sure enough, the tubes were raised. Pushed them down and the micro phonic is down to a manageable 5 secs.

Why doesn't damping the tube make the microphonics better? Simple--the tube glass isn't ringing, it's the internal structure of the tube, which you cannot touch.

 

The best solution would be a small antigravity device to float the tubes in open air, but short of that, the solution we arrived at is the best from a production standpoint. In happier news, though, we're now applying an additional, long-term noise sort on testing to weed out the unacceptable "ringers."

We also tried lots of different operating points on the 6088s, as well as running the heaters under-voltaged, and all the little things we've learned over the years about tubes. Remember, Mike Moffat was one of the guys who brought tubes back into audio--in the late 1970s. We've been doing this for a while...

thegunner100 did a good job of digging up the quotes from Jason.  I still have the "O" rings on my tubes.  When I initially documented the process, the tubes seemed to really quiet down from a microphonics standpoint when the RTV silicon was starting to cure.  Once it finished curing, there was very little improvement in the noted microphonics issue.  Basically, it's a "feature" with the Vali amp and nearly impossible to work around.  But, Schiit has apparently been selecting the tubes to minimize the effects to a degree.

 

Now, putting all the jibber-jabber aside, we all just need to appreciate what it really is.  A $119 amp that's capable of "showing up" the competition a few hundred bucks north of $119.  I've been swapping amps all around over the past few years.  The Vali is the real deal.  Enjoy the amp, put the rest of your cash aside for other upgrades or music.

 

To get the most out of the Vali:

 

1) Turn the amp on.

 

2) Plug in your headphones - preferably with a headphone extension to keep from moving the amp.

 

3) After about 30 seconds, place the headphones on your head.

 

4) If you need to apply volume adjustments, do it with the level adjustment in your player itself (e.g. Foobar).

 

 

Additional:

 

* Keep the amp on a solid surface so it doesn't jiggle or shake around.

* Talk nice to it.  

* Appreciate what you have and the bargain you've obtained for $119.00.

* Enjoy your music!

READ MY MIND!

 

Thus far, forgetting it's CRAZY-low price, this lil tube headphone amp has been loads of fun!

But, $119????

 

I'm just psyched I'm hearing here what I heard at CanJam at RMAF 2013:

(our CanJam report in Audio360.org - including comments on the Vali)

 

W/ my LCD-X and Mad Dogs (current version): Thus far (more cans to try of course) the sound is excitable and engaging, warm, but NOT in an overtly romantic or glossed-over kinda way. The sound has all the audiophile buzzwords I've been writing for years: Transparency, detail, authority, hell - taking a cue from @wje  - 

 

I'm just havin' FUN with this amp! and I'm using the lil HRT microStreamer as the DAC ahead of it (has a dedicated line-out) - because I didn't wanna throw one of my more expensive DACs at it yet.  This lil combo (altogether under 400 bucks) has me tappin my feet, lightin' up, and discovering tunes I haven't listened to in awhile.!!

 

HATS off @Jason Stoddard and crew!!

 

My review should be just as glowing as my first impressions in the report if this keeps up!!

H__ YEAH!!

 

Me too!

 

and I told Jason I couldn't look myself in the mirror if I asked for an industry accommodation price for this one!!

:eek:

can anyone explain how pair sounds in your experience?

thanks.

I have this combo and enjoy it very much. I enjoy it a little more than my Vali HD650 combo as I find it a little too laid back for my taste. I prefer a little more of an analytical sound so enjoy the Q701 more but you may find otherwise, it is a very personal thing.
Enjoy the music.

A very personal thing indeed!!

Well said.

 

After all, we're all reacting to art (music) and the technology that reproduces that art form (which, is itself another form of art)!!

 

I need resolution, but I also look for something in a system that's difficult to encapsulate: Soul

I want it to translate the emotive energy of the music. The power in musical expression - and that's not always perfect.

 

So it all comes down to taste.

That's only one of the reasons this community is such a great place to share about all these things:

We all bring different experiences, biases, tastes, and history to our listening experience.

 

Back to topic:

The Vali is sounding fantastic over here. I got it isolated on a Bright Star base with a Walker Audio puck atop the chassis because I heard about the noise issues before...

Honestly, I forget what they said it did (the Walker puck), but I just use it for mass loading - helping to still resonances from continuing past the chassis,

 - that's what sold VPI magic bricks for so long - LOL

 

and I've been loving my music through it:

I've been particularly lovin this record - Shlohmo's Pretty Much Amazing EP.

Dig his mellow, almost-trap like sound...

jason had responded earlier somewhere, its the choice of tube

they've changed the adhesive used in the dampening , earlier units were arriving with tubes lifted off the pads.

i just pushed my tubes back down onto the pads, and i just set my volume, after about 30-60 seconds, no ringing

no biggie !!

Again the vali is a magical little tube :D, the transparency of Solid State the heart and soul of Vaccum Tubes! I need to write up my review still <.<

That's a helluva quote!!  :D - I might have to steal it for my review - but I'll give you a credit!!  ;)

Just kidding

But, seriously, well put!!

AWESOME

good to hear!

I haven't had any issues

Let me just say that I already notice a difference in sound quality, most likely from the modi I bought as well. Now, there is one thing that I'm wondering about. Since I have to keep my volume kinda high most of the time to drive these headphones, I'm not sure if this is my fault or just the equipment burning in. First of all, the bass isn't as strong as I expected. That may improve later on though because I haven't even used it for an hour. Lastly, I noticed a slight buzzing when there are vocals. It's kinda like the sound your voice makes when you talk in front of a fan. It only happens sometimes, but I'm not really sure. 

 

Everything is great otherwise, and maybe it will resolve itself when it burns in anyways.

Hi guys, I'd like to add on to these. 

 

This amp is amazing, and I can't believe I only spent $120. Now at 20+ hours, the amp is still improving. I optimized my media player's preferences so they use the Modi's full power. I take back everything I said before. It must have been the amp still breaking in. The bass is much better now, and it's still only at 20 hours now. At full volume, there isn't any noticeable distortion anymore either. Again, I'm using DT880 Premium 600 ohm headphones, and using my computer as a source, I have no issues with driving them (and I listen to music kinda loud too).
