I will not explain how or why just kinda like to throw out tidbits to get everyone to think..

40+ pairs? Who did you rob/kill? It suspiciously sounds like you might have played out my fantasy of finding a 100 lot box at an auction... and nobody recognized them for what they were. You learned German and browsed their classifieds to find them!

OK, rocking the Orange Globes, and thinking these RTC tubes have got their work cut out for them.  In my mind it'll be hard to best the OGs at all, let alone wipe the floor with them.

 

The OGs have it all, everything most who have turned to tubes are looking for!   The bass is strong and nimble, the treble is sparkly and smooth, refined.  And, oh, those mids!  wink_face.gif

 

I am going to listen to these RTCs with an open mind, but as of right this second, I'm a bit skeptical....

They started off muddy, harsh treble and pretty congested, but everything opened up, should get better with more hours on them.

I've burned mine in for 12 hours or so and already sound fantastic. Really recommend these if you're a bass head. Sounded a bit congested and muddy before burn-in and treble was harsh, i can only imagine these will get even better as time goes on.

 

Flavour: Bass is tight and impactful, lows/mids in general have a nice gravel like quality to them, rock guitars sound amazing, Mids don't seem recessed, treble is very smooth and detailed, soundstage has good width and depth, not quite expansive but certainly above average.

 

I think these tubes are fantastic for the price, worth rolling in if you haven't already got plenty of the "popular" warm tubes.

Should be interesting to see how things transform (touch wood) over the coming hours!

 

(very early impressions so take with a large pinch of salt!)

 

I just left these running some white / pink noise and frequency sweeps for a few hours and then spent the last hour or so listening to a wide selection of tracks (acoustic, rock, classical, r&b etc.).

 

I'm not sure whether they should be showing much of an improvement so soon but after 6 hours or so burn in to my ears these tubes sound nothing like they did just a few hours ago. Much more open sounding now, mids are present and correct (vocals have improved immensely), great bass, pleasant treble (I don't like too much). Whilst I hoped they'd show some improvement I really didn't expect anything so marked at this point.

 

They are also a lot less noisy than the stock tubes when I'm listening to my D2000s and the bass on those phones, which has a tendency to get flabby, is noticeably tighter and better defined. The HD600s are on another level and seem very well matched with these tubes.

 

If they improve some more then I'll be very pleased indeed, but if not I still think they sound killer for 15 bucks. The incoming Bugle Boys will have a hard act to follow I reckon biggrin.gif

Well, I'm looking forward to this!  If they're really that good, they really must be special!

 

But I'm afraid that they'll arrive while I'm out of town, it'll probably be June before I can start the shoot out...

I'm really not surprised!

 

One of the most common things I notice with green tubes is congestion, and that sounds a lot like what you were describing when you first listened.

 

It is kind of amazing how tubes can change, isn't it?

 

Burn in is kind of controversial here on Head-Fi, some people chalk it all up to placebo.  But with respect to tubes, it's definitely real!

I got a replacement 68 OG from Mercedesman today. One of the tubes I originally got was very noisy. I put about 30-40 hours on the originals and only sent one back as mercedesman said he recorded the values. Should one tube having more hours than the other be a cause for concern?

Probably not.  Their life is rated at something like 5,000 hours.
