what makes the LD's buggy? i've had the MKIII and have the MKIV SE now with ibasso D4 as DAC since i dont do portable much now.

well looks like the only way the find out is burn a bigger huge in your wallet at this point. lol   unforunately one needs to try it with a better amp to know if its right for you; err rather the headphones with you listening to them.

@kwang411   the cv4010 are likely from mullard england. since thats the standard naming for European tubes. and yes same tubes from different companies will sound slightly different. even the same tubes from mullard made from vastly different year will be slightly off as well.   and as...

yes please do continue the burn-in with stock. i'd say 100+ hours. and do the same with the others. so that way u have a roughly estimate of the stock compared to the EF91/92 improved tubes.   oh be sure to put a variety of music into the unit with burning in just to cover your bases. and...

man i never got that with my new MKIV SE. boooo

silver,   i think your best bet is to get the grubDAC seeing you wanted to compare the two chips. the grubDAC was designed to utilize either one of the chips. and if you get the kit you can get the other dac chip for like 4 dollars more. so its a good way to test just the chips. rather then...

man i just got 16 of these for 17 bucks. i cant help you on that bundle. but they do sound good. some of the ones i got i noticed microphonics. i have some cheap rings i put on and it helped. but not all are like that. oh mine batch came in two flavours. some had this "rib" that ran down its...

ohhhhh like rust....yeah its suppose to be an even coat of blackish grey  

  Quote: of all the ones i have even the used ones i got its just grey/black ish never rusty looking. you mean rusty looking as if its reddish in colour on the center barrel/plates? that's a bad sign i think.

its 20 for the 2, it was originally from my MK III purchase, that owner rolled enf tubes that the lettering if rubbed off save the "tung *ol" from one tube.   where you located? at least the lettering rubs off lol, so they are at least really tubes. was told that some mullards were...

oh Cr*p, its out on delivery...what speedy service....

hmm the stereo to mono downmix is.....hmmm not what i expected. i might need a true mono source. its too bad my technics turntable is missing the balance weight. the downmixed sound is muddled.  JK the MK III is suppose to get warm all over, just like when you're in love. LOL mine did that too...

i do use foobar i didn't know that. thanks. maesto, what cans u using? the ef95 i find the tungsol are very nice or the mullard cv4010, i dont like the rca. since they give too much bass for me. I have the GE 5654w (non 5stars) they are close to the tungsol. the mullard ef92 and 91 i have seems...

  Quote: mordy, i'd like to try what you suggested. the prob i have encountered is the fact that virtually all the music i have on hand is stereo, which means that the left and right channel plays different tones as per the song  per artist. either i find mono tracks and mirror them or...

  Quote: x3dnd3x,   the 6h30p/pi are like the little brothers of the DR version. the DR version is what we call "mil-spec" tubes i suppose. since they are rated for  higher reliability and extra long life. they are rare to say the least, since i've only found my 2 pairs from...
