ShuGuang CV181-Z tip:

Use a socket saver. While the tube itself will just barely fit, I believe the ceramic base touches the tube opening on Lyr 3 and transfers the tube heat to the Lyr 3 case. Without a socket saver, the Lyr 3 runs super hot with the CV181-Z -- much hotter than with a normal-sized and fitting 6SN7 tube. After using a socket saver to lift the ShuGuang tube, the case temp was much lower and on-par with temps when using a plain ole 6SN7 tube.

Thus endeth the lesson.

Hope this helps.

It does, indeed. Thank you.

RE: Socket Savers

I found these work nicer than others I’ve tried, not overly tight on either side. Plenty of room in the LYR3 opening so no contact. Currently burning in my Psvane CV 181 TII’s matched pair. Purchased 4 of these savers so I’m good for future developments in …

Great minds think alike. Mine looks exactly like the one you recommended. As stated, fits nicely inside Lyr and secure mounts on either end.

^^^ I'm a given, but several others come to mind ...

Unfortunately, you did not make the cut.

I am approaching 100 hours on the foton. Definitely improved. Not sure it's out of the "friend zone" yet. still a bit etchy in the mids and upper bass. Not as clean as others so far. will put back in the oven to bake for awhile...

My experience exactly with the Northern electric tube

So, I was very surprised tonight. I've never heard the HD600 with Lyr 3 until tonight - well other than a few minutes here and there. When they say that it scales with better amps, this is no joke. These things were phenomenal, simply outstanding tonally, dynamically, you name it. No, not the best, but for $288 brand new, you'd be hard pressed to find a better match anywhere near that price. The only real quibble I have is the warm smooth bass. It's a little humped at 100hz and overly warm there.... so a tad of bloat... just a smidge. But I dare not touch that area with EQ.

Now I understand why all the friends on that other forum sport wood over HD650 and schiit amps.

Using halo getter, pot at 1:30 - 2:00 (low gain cause it sounded cleaner, more pristine to my ears). Dac puts out 2 volts, but I drop 6db at my EQ software. I only use EQ for surgical treble correction above 3 khz (to eliminate that very slightly metallic sheen the HD600 can present). Otherwise, neutral city baby. Below presents all treble frequencies within 1/8th octave as perfect equal loudness (within a db I'd guess) with controllable sine sweep tones/noise.

combine this with a very resolving and layered tube, and WOWSA!

Schiit's getting ridiculous:

I'm guessing this isn't what Schiit had in mind when they suggested we can use adaptors

The Osram L63's i haven't had a proper listen yet, just loaded up the adaptor and chucked in the tube tester to make sure no cross-wired or shorts, had a listen for a couple of minutes and... yes. Based on an initial 2 minute quick listed, they are up there.
Will have a proper go later when missus stops hogging the TV (use it as my PC monitor)

It's official. You have gone completely bonkers!!

You haven't seen bonkers until you've seen this in one of the the Felix Elise threads...

And yes, in case you are wondering, I'm pretty certain that the power transformer ate itself.

LOL i don't thin k i'll be going that far.

The L63's only draw 300mA heater current so both together same as a single B65 / 6SN7


Now about those L63's..... oh boy If Lyr 3 has a "party mode" these tubes enable it.
Started having a proper listen now the missus has cleared off to bed.


I'll compare to the ShuGuang CV181-Z seeing as that's the most recent tube i've listened to.

Bass is a tad warm but well defined, Mids are more lush and full bodied, Treble has that extra little bit of air and sparkle that the ShuGuang is lacking, the treble extends a little bit further as well. he decay is on another level, if i had any emotions the decay ought to bring a tear to my eye. Soundstage wise it's very 3D, image a tad better than the ShuGuang, these aren't at all burned in yet so i expect the width to develop a bit more. Currently as wide as the ShuGuang but not as wide as a Brimar clear glass orange print.


So far considering not properly burned in these tubes are blowing me away If they are truly representative of a proper Marconi/Osram B65 (2 x L63 = B65) then i can really see why B65's sell for so much given their rarity and sound. But for me personally £400 for a B65 is going a bit far in a £600 headphone amp. You can get pretty near to this sound for less than $100 in american tubes.


If i can get a proper Marconi B65 for a good price i'll give it a go to see if it's the same sound as 2 L63's Then if so i'll sell it and recoup some cash lol
