Ah. I don't have any other headphones besides HE-500's - why do headphones have to be plugged in? Is there any other way I can burn the tubes in without using the HE-500's?

Awesome. Will do that, thanks for the info. 

Whats the typical time frame on tube burn-in, how long should I leave it going for?

Back to Amperex PQs that make the Mad Dogs sound sooooooo seductive.

The 1979 and 1980 Voshkod rockets sound better then the Amperex by a mile and even beat the SQs in most respects.

One note:  I have collected a large stash of these V-Rockets and I noticed their seems to be two versions across date codes.  One with a long gray shield and one with a long shiny shield - kinda'  like the S&H CCa.  Except the sound on the V-Rockets with the shiny shields sound way better!  Much more open, with a more extended and detailed high end (unlike the the S&H CCa where the gray shield are superior).  I have posted a picture, the shiny shield is the 3rd from the left and the gray the last to the right.

Try them both, but don't judge them until you have heard the shiny version.   Best sounding of the date codes are the 1979 and 1980s so far.

V-Rocket vs the Amperex - way more detailed, just as musical, wider deeper sound stage, way more dynamic and open, deeper tighter bass.

V-Rocket vs the Philips- Holland SQ Halos - the V-rocket again excel, the SQ are a tad more liquid in the mid, but the V-Rocket beat them in dynamics, openness, with a wider and deeper sound stage.  Both tubes are very musical, but the V-Rockets have a deeper level of detail.  The detail is so great that I could things like light cymbal taps and guitar plucks that I had never heard before, even on recording that I've heard hundreds of times!  This level of detail adds to the ambient clues that provide a very realistic 3-d sound staging.  The musicians are holographic vs stacked flat cardboard cut-outs.

The 1979, 1980 vs later 1980s and 1990s V-Rockets.

They are all very close, but the earliest date codes are the best - with a more dynamic presentation and greater detail.  I'm arranging to acquire some 1960s date codes so we'll see how they sound.

Awesome tube!  especially for the money! 




Yes, my hunting them out and now my initial statement of early impressions was basicly a nod to your posts. I've been breaking in for 20hrs or so. Last listen was around 8hrs in. They seemed to have more space without loss of presence. A little more punch and boom in the mid bass.

Got 4 of them for 5$ each. Value is off the scale.

Your apple earbuds will be fine, just be very careful with the volume pot.

Better yet, turn the volume down in whatever player you use to play the pink noise sample, then you can turn up your Lyr without blowing the earbuds.
However the load will be negligible.

I'm doing my Voshkod burn in right now without a load. I don't, think it matters due to the way the tubes are coupled to the output,as they run flat out, just the input signal is pot attenuated.

My brother grabbed a single ended 1/4 jack and soldered a couple 50 ohm resistors to the ground point. That was used to break in his modded Asguard (which nearly outperformed my Lyr!) Don't quote me on those resistor values,I'm not 100% on that.

I made some jump like Mexican jumping beans when isolating a bad tube. They survived... dammit.

Go to the dollar store. But for god's sake man.. whatever you do, don't listen to them!

I wonder what I should try first.. How long does it normally take to burn tubes in?

What I do notice is that the treble is very high on the Lyr. I get listening fatigue if I turn it loud!

 

 

I use the HE-500's and my setup is certainly not bright. I've actually had to work at getting the treble where I want it. 

 

Which tubes and which cables are you using?
