I just finally bought these today (damn you brick and mortar boutique audio shops!) and while my Schiit stack and o2 power these well enough (I first heard these on a Taboo III) the baby Little Dot holds its own even in low gain! The detail level is similar to the o2 combo and Schiit Magni and Modi stack. SO just saying, I think this little guy will scale a bit if I fed it better. Anyone have a super nice/expensive/amazing DAC feeding the MK1+? What did you think?

 

I had a chance to listen to the HD800 (300 Ohms) recently, and like you, I thought it sounded fine on my LD1+. And I have been I wondering how much of this is a direct function of the installed op amp? Or is it more complicated? For example, the technical info for the LME49990 op amp explicitly states that it "Easily Drives 600Ω Load." I didn't try the HD 800 with the stock op amp, so I have no idea if that would have made any difference....

 

Unfortunately, the best I DAC I have used with the LD1+ is the Schiit Modi, so can't add anything....

You make a good point about the opamp... I do have the stock one around here somewhere to demo... Now you've gone and made me curious!

I'm going to order an Uber Bi-Frost in a couple of days.

I'll tell you what I think when I get it with the little dot.

 

I'll install my Voshkods and LME49990 op amp in the Little Dot 1+, Uber daughter board on the bi-frost, it will all be played in my Shure 840 headphones.

Happily, with another 20+hrs on them, things are "coming together" quite nicely - ie still tremendous detail, but with more coherence. Bass is developing a bit more...(either that, or I am 'habituating' myself to higher volumes - not to mention early deafness!). Whatever, I think I am falling in love all over again. Oh the pain...

 

And I have been having the same experience with the 6DJ8. At first, the vocals just didn't seem quite right - too distant. But again, it is that spacious sound stage that takes some time to get used to, I think. This evening I heard background vocals that actually sounded like the singers were located "behind" the lead, and everything just seemed to be where it belonged. :)

The Haltron 6CS6

 

The 6A2П's from the October Ukraine, Vinnitsa factory.

 

Then you plug it in and the Magic Happens! (Click to show)

 

 

The first song played on the 6A2П's in EF95 1-7 was BB Gabor's Moscow Drug Club. :D

Sounds good!

 

I'm really curious about the scalability of these amps with better cans, and how our choices of tubes affects the end result we hear.

Ah yes, it appears you have a pair of Toshiba-made 6CS6. These are nice tubes. :)

Burning in pair westinghouse 6AV6 tubes. First tubes that needed jumper change to ef91/92. Tubes are made in Japan and they look identical with NEC 6AV6. Sound have been very good from the beginning. Tungsram 6BE6 seems to sound little better in ef92 mode , but sound still has somekind dull filter. Westinghouse does everything way better and clearer.

My NEC 6AV6's arrived today in good shape. Seller only uses newspaper to pack with...

Lopping off the two pins later tonight, and will give a listen this weekend.

Anyone have any feedback on some good 6AV6's? I love my Mullard 10M 6AV6, the RCA is ok, and I only have one JTL Sylvania since I cracked the base on my other one clipping the pins.

Any of what I would call the "GE-style" of 6AV6. These have a box-like structure mounted on the top mica and "mountain peak"-style diode plates. To date, I have found FIVRE, Toshiba, Tung-Sol and of course GE.

 

Toshiba

 

 

Tung-Sol

 

 

FIVRE

 

 

GE

Got my socket today looks like its not going to be easy to solder the wires because you cannot remove the top part from the housing completely whithout the pins coming out of the housing plus my wire is 22 gauge will see if its small enough .Thats all the space i have to work with 5/16 wide

Hi Gibosi,

 

"Ah yes, it appears you have a pair of Toshiba-made 6CS6. These are nice tubes. :)"

 

 

I have a pair of Raytheon 6DT6A made in Japan plus the Siemens Foreign  EH90 and Haltron 6CS6. They all look like they were made in the same factory. Since we know know that there is a connection between Hitachi and Raytheon, how can you know if all these tubes were made by Hitachi and not by Toshiba? (Perhaps Toshiba made them for Hitachi when it comes to the Raytheon tubes?)

 

Have not been able to find out much about the production and differences between the Toshiba and Hitachi tube factories.

 

The bottom line is that these are all very nice tubes.
