OK well yes I mean I have hardly burned them in. I mean I have no idea how much use these had but supposedly they've been collecting dust for decades.

If they go backwards because they are still being burned in, then OK.

I wouldn't be surprised if I haven't even cracked 100 hours yet, maybe not even 50. That includes my headphones too.

So if I am really going to see that much of a dramatic difference at 100 hours, then I'll try to burn them in over the next 2 weeks.

 

Yes - give them 100 hours before worrying too much ... they'll probably still change a little after this time, but at least by then they should have largely stabilised as regards sound quality.  New Old Stock tubes and tubes pulled from testing equipment often even sound noisy and distorted till they have been "run in" a bit.

Thanks for the replies.

BTW since you said the Mullards have a lush sound. And I do like a syrupy, velvety, thick, lush sound...any recommendation here?

I rolled back in Ediswan tubes tonight after months of listening to Amperex USN-CEP's. First impression was the Ediswan's bass is less controlled and not as tight, but the treble is crystal clear. What struck me most though is how musical the Amperex tubes are comparatively. It's the ability to present the music as a cohesive whole, and render complex passages of music effortlessly is where the Amperex tubes seem to excel. The Ediswan's are great tubes, but they aren't on the level of the USN-CEP's. Amperex makes some highly enjoyable tubes.

Yep - either of the Amperexes (Bugle Boys and Orange Globes) are very warm - not as lush and syrupy as a Mullard, but I think they also do detail and dynamics better, whilst not being as lean and clean as some of the German tubes.  The other advantage of the Amperexes is their reasonable price (at the moment).

Tube Depot are out of stock completely, but look at that price !!

I've read about Brimar, and saw some in the classifieds here.  I'm not opposed to spending that much, but not much more.  Mullards just aren't tempting me for some reason.  I laughed when I saw the $1K tubes on Brent Jessee's site (hums a few bars from "When I Win The Lottery" ;-)  Can't recall the make/model.

 

Anyway, I jumped the gun before I saw your post (and evshrug's in the Q701 thread) recommending the OGs, and got 1961 (January) large O getter Bugle Boys.  On the plus side, the Matsu****as I got from Upscale sound fine with the Q701.  It'll be interesting to compare them with the Bugle Boys, using the Qs and HE-500.  If I hear what you described earlier, the BBs should help the HE-500's soundstage.  We shall see :-)


I'm pretty psyched to get some Bugle Boys.  They were the first tube I read about, but ended up with others to start off.

 

Cheers.

Thanks for mentioning the Ediswan.  They're on my radar.  What cans were you using?

Let us all know what you think when they arrive. :beerchug:

HE400 and HD650- They're great with both.

I'm thinking about some bugle boys for LCD2's. I have OG right now but want something a little more resolving while keeping bass

Thanks.  I know the HE-500 is a bit different from the 400 (some might say more than a bit).  Guess they're still on the radar.  Oh look! so is Santa  ;)

Completed a tube faceoff last night. I was able to pickup a matched pr of the Amperex USN-CEPs a while ago on Audigon (sojs was the seller). So did a faceoff between the USN-CEPs and the best of my Voskhod collection. Using the Lyr and my HD800s with the Moon Black Dragon V2 cable, and my Magnepan 1.6qr and hybrid amp system.
Well here was the results after 3 days of tube rolling:
First Place - Voskhod 6n23p 1975 silver shield wire getter post. Supremely musical, incredible layers of detail. But the winning factor, the ability to just capture the emotion of the music and sweep you away. Just an incredible flow to the proceedings - layers and layers of detail - never muddled or congested. Soundstage deep and wide, on the Maggies just breathtaking holographic. Albums went by last night as I just became absorbed into the sound. Whether on the lyr/hd800 system or the Maggies just incredible.

Second place tie: Voskhod 6n23p 1975 gray shield, plate getter post. Well I was initially expecting these to take the prize, but they 'only' tied for second place. The margin between these and above was small and came down to that flow equation. Very sweet sounding tube, silky textures, great detail. Deep layers of sound, all clearly distinct and just as silky smooth as the main sound. On David Gray's White Ladder album - 'Please Forgive Me' has the gravely voiced Gray singing, backed ever so subtly by these violins. These could be followed easily, but most important were just silky smooth, a great contrast to Gray's close miked voice. The later bass drops had slam and deep extension. The opening drum taps realistic, the bells just hanging in space - with reverberations prolonging into the deep black background. The cymbal taps clear, again hanging in holographic space. Gray's voice has this capturing spacey quality. All excellently portrayed. Again these only lacked that last bit of flow and just a bit less depth of detail from the above.

Second place tie. Amperex USN-CEP white label 1965 USA. I really love this tube, unlike other Amperexs l have tried these have greater detail, and aren't so euphonic. A true match for the best Voskhods, wonderful flow, large sound stage, sweetly musical. Just a touch more layed back then the above Voskhod Rockets. Backgroud textures were clear and silky smooth. On Florence and The Machine 'Dog Days Are Over' no etch on Welch's voice which can be heard on some tubes. I use this track to test for this and in the middle section - for congestion - as it gets very loud and busy. Not with the USNs, everything cleanly seperated, easy to follow, no strain at all. The main difference between these and above Voskhods, especially the 1st place winner, a slightly more layed back presentation and a touch darker. Some may prefer this depending on their source. Mine was a tubed DAC - APL NWO, for those with a solid state dac this slightly darker nature may be prefered.

Third place: Voskhod 6n23p 1975 gray shield wire getter post. These were the darkest of the group, and lacking a slight amount of detail. On Gray's track, I had to work a bit to follow those background violins. They were there, but just didn't have the clearness of the above. Their silky texture masked a bit. A little congested and a bit of etch on Dog Days as well. Solid bass slam and depth.

Well I used other favorite tracks in these tube rolling sessions which I won't go into detail. Needless to say the top three rocked as well on Zepplin, Brand New, Springsteen and others. Excellent on some of the Jazz and Classical stuff as well.

What year were your US-made Amperex 6922 manufactured? I have 1961 and 1964, and they do not sound the same. The 1964's have a slightly leaner and drier mid range.

 

PS: I have some 1975 Voskhods coming, although I do not know if they are grey or silver. :)

These were 1965s. I can relate to differences in years. With the Voskhods it can pretty dramatic. I'd like to hear your take on the different year USNs. Also note the different construction on the 1970's Voskhods, whether the getter post (that holds the inverted saucer getter) is a seperate wire or a plate that is part of the shield. That was noted in the review, they do sound different. And to add to the confusion the Reflektor factory made a version with the single wire getter post that sound the same as their Voskhod brothers. All the Reflektors I heard, including the 1975s, with the standard dimpled dual getter posts are just mediocre.
