Yet to try it but will give a good feedback once i compare the difference the EB and the one i got.

Don't forget to mature them (45hours or so) before critical evaluation. Some tubes change a little, some change a large amount. Once they are mature and stable, evaluating them becomes much easier because you can repeat the listening session as many times as you want, and the results are always the same.

Differences between tubes becomes clearer and more easily explainable.

Gotta love those NOS tubes. So addictive, you must buy more!

I haven't had so much fun with audio in a long time. Who would have ever thought, you could have tubes for different moods.

I have a reference set of tubes I use every day (Sylvania 5654's Round Getter, Black Plates), but sometimes I roll in a set of Mullard M8161's or Amperex EF92's, just to savor the difference. The whole concept of tube rolling is just so cool, and never boring. IMHO of course.

I removed my tubes before they cooled down, what are the consequences of my stupidity?

Thats true Penchum. The power tubes sounds very sharp after 4hrs of listening. But seems to tone down after the 10th hour.

Just put in the new tubes I got. 16 hrs on power tubes and fresh for the new voshod tubes. I have got instant hair raising experience which i never had on my MS2. The low, mid and high suddenly just came alive on my MS2. The jingles and the bass suddenly become so alive. The bass is more controlled and it travels. I dont know why but it really sounds better then the voshod EB and the tungsol i got.

Now for the loud speakers which i hook my mk3 to my power amp. Staging has improved drastically and all the low, mid and high is so much clearer then the tungsol and the voshod EB.

I must say worth every penny spent....

Now like Pehchum said...45hours for critical evaluation.

I thought of that, I hope I didn't mess anything up.

Quick question before I pull the trigger on a MKIII with the eBay 30% MSN thing.

Firstly, I am fairly sure, but this amp will mate with my HD580s pretty well, right? I will mostly be using 580s for jazz, classical, and vocal works, lighter styles, which I've heard tube amps excel at.

Secondly, as this is the tube rolling thread, would you guys suggest any immediate tube upgrades so I can get them at the same time? This will be my first tube amp. (Nothing super expensive please)

^It seems pretty universally recommended that with the MKII, at least at some point, you try the Mullard M8161 driver tubes. So, getting them right off the bat may be a good idea.

Then again if you don't start with the stock tubes how will you be able to understand how much better "upgraded" tubes are?

EDIT: Woops, I meant to type "...universally recommended that with the MKIII..." not MKII.

If it indeed is universal that most upgrade to them, I shouldn't need to know how the stock ones sound, though I'm sure I would try them anyways.

^Don't worry too much about the power tubes right away, though. I'm kinda' leaning toward liking the stock tubes over my EH 6H30Pi Gold tubes (which are "supposed" to be the best). It may just be that the Golds aren't burned in fully yet, like I had the stock ones, but the Golds have seems to take out a certain amount of bass... which I needed with my AKG K701s.

Ok I guess I'll just go with stock and see what how I want to tweak it as I go. Thanks.

I actually just missed that by a couple of hours but I see that he's still selling those. I will buy them now. Thanks!

BTW, I think I have to start logging out and closing my head-fi windows after I get these. My wallet has taken a fairly good beating for the last 3 weeks.

Don't mix up what I mean about the power tubes and driver tubes, though. The M8161 driver tubes are a must try, as they say, but the power tubes are the ones that I would personally leave stock, for now.

Just so we're on the same page
