Schiit Lyr - The tube rolling thread - Page 2

What is really frustrating is all my tubes are so far away and I have so many varieties of these different ones I would like to try. So out here on this island I have to buy what I may want all over again at higher prices and tubes I don't really need to buy. Well you can never have enough of the glowing glass wonders! lol

I got a chance to listen to two sets of tubes today, go back to page #1 for the reviews.

I was pondering the HP rabbit hole depth, and after looking at your HP gear pics, I realize it goes just as deep as traditional HT gear.  Nice collection!  I'm convinced you need a larger tube collection.

 

I rolled in a pair of 6N1P Sovtek tubes 4 days ago.  Not terribly impressed, although the midrange is an improvement over the stock JJ's, however the low frequencies are lacking.

Ordered a matched pair 6N1P's direct from Russia.  I wasn't expecting a whole lot since they cost $2.00 ea, and the only signage is OTK, which is military spec tube.  First impressions; they're the best (JJ's, Sovtek, Gold Lion) balanced tube I've rolled in the Lyr to date, however, they're only hours old.  Time will tell, but I'm giddy with excitement.

Cans:  AH-DM5000/AKG-K701

is this the one? this is what Schiit is selling as an alternative tube for Lyr.

Not exactly.

When I'm done crunching numbers for the day, I'll pull the 6N1P's from the Schiit and post actual pics.

There were different tube manufacture sites for the production of the 6N1P as well as different versions and periods of time when the sound produced was different due to varying manufacture quality control standards. I had a friend who was an engineer that worked with tubes in the USSR. He explained a number of years ago to me, the different 6N1P types and the reason for the different sounds as well as differing quality within the same designation. Just like tubes from the US, there was a golden age and one that was devoted more on just getting the tube out the door. Since the 6N1P as a tube was used longer in circuits, later in the 20th century, than tubes in the US, because of military use, they are often still of higher quality than the corresponding time period of tube production in the US and other areas. Tubes were still being produced in the USSR long after almost all tube production had ceased in most other countries. 

So there will be variables and obviously, with this, sound differences in the 6N1P, not only with EV or IV or E designations but on production facility and when they were produced. A general sound quality can be described for the 6N1P but not in absolute terms. There are 6N1P's with better bass performance and some that are dry and a little gritty in the upper frequencies. I find the best to be from the mid sixties in black flat plate but they are nearly impossible to find now. To me the tube just mentioned a 6N1Pe, is the most balanced and smoothest sounding but it also has a slightly different design because of application, which was in pure analog circuits.
