post #1801 of 6944

Just a little continuation of 6CS6-strapping: For the Siemens EH90 (see here), so far in 1/7 some focus is lost, the tubes sounds not so engaging. Unstrapped is better with good tonal balance and more ambience. 2/7 sounds most focused and quite detail rich, however it is also relatively bright and could become fatiguing. Definitely worth a try if that matches your system.

 

Mordy, you got quite a set there with 25 tubes. Happy listening after your break!

Just tried again the 6by6 unstrapped ,1-7, and 2-7 and verdict is the same i prefer with the Senns unstrapped because sound is more transparent i judge with my go to tune imo the 1-7 i did not really appreciate the bass as much as the 2 others on the 2-7 theres a xylophone pass that is not as clear as when the tube is unstrapped so unstapped as overall better sound qualitys imo.

Hi guys, I've only posted on this thread a couple of times after recieving my first hybrid tube amp (LD1+), so I don't know much about tube rolling, but I am following this thread and trying to learn for myself, but in the meantime can anyone recommend me tubes that are directly compatible with the LD1+ ( I would like to just be able to plug these right in without any modifications to the tubes please), to use with my Grado SR325is's. What I would like as far as the sound of the tubes are:

A very upfront, aggressive presentation with nice tight bass, crystal clear detail and crisp high frequencies.

If anyone has experienced this type of tube signature (direct plug in) with the LD1+/SR325is, I would greatly appreciate some recommendations. Thank you.

When someone says that they want bright and crisp, I immediately think of triodes.  However, you do not want to use any mods...

 

I haven't listened to any of the traditional LD tubes in a long time.... But as best as I can remember, the Voskhods might fit the bill.

 

 
At $3 / pair, plus $12 shipping to the US, these are very high quality tubes for not much money, so I think they might well be worth a try.

Thanks for helping me out again, and I will definitely buy these right now to check them out, also thanks for the link.

Same here, crystal clear and upfront immediately makes me think of triodes. While not "natively" compatible, these aren't exactly hard to adapt (cut two pins off and protect with tapes, EF92 jumpers; more on that maybe 30 pages back or so. A 6AV6/EBC91 would fit your description very well.

 

Of course, the old 6AK5 type Voskhods would also fit the bill... But they're actually not that cheap if you only have one pair coming for Russia...

 

Come to think of it, if you just just want to plug and play an old and native tube, the Mullard M8161 would be much better (tight tight bass, shimmering highs, those were my favorite tubes until the better and more powerful types came around).

 

(Though I would still recommend a triode or other more recent tube type over the classic Voskhod 6ZH1P-EV and Mullard CV4015/M8161, I currently have both these tube types for sale if you're interested -link for classified a few posts back- including burnt-in Voskhods, and these are pain to burn-in imo...).

 

Actually, remembering Acapella's and my impressions, the 6EW6 type would also fit your bill quite well, and those were in the last batch of "natively compatible" tubes we'd found back 6-9 months ago. These are like the M8161, but more powerful (got a pair of those for sale too in fact; it seems I have a pair of everything for sale...).

I ordered tubes from the link the that gibosi posted for me last night, so I will wait until they get here and have a listen, and from there I will get in touch with you, I'm curious about the "natively compatible" tubes for right know. Thanks for letting me know that you have few different tubes for sale that may fit my needs. And thanks for the correct terminology (natively compatible), instead of using the words (direct plug in) like I did.

BTW, I purchased my LD1+ with upgraded 6AK5W tubes, and yes I like the sound, but then again I have nothing to compare these tubes to, so thats why I would like to try some different sounding tubes, but yes they do sound nice. Thanks you.

Out of the olde worlde native types, the M8161 is still on the top of the pile, and fits your description perfectly. I believe it was very well rated on the first -founding- post of the thread.

 

You might be waiting for a while before those tubes get from Russia to you though... Anywhere between 10 and 25 business days.

 

And if you haven't read up on the first 30 pages of the thread, expect these tubes to need a burn-in time over 100 hours (many have reported 120 hours, I found that the tubes settled after 105~110 hours, and I had bought these exact  tubes from the same seller btw). They are some of the best sound you can get out of the 6AK5 family.

 

Have fun comparing tubes at any rate; it's addictive!

I was going to ask how long it takes for tubes to burn in, but then I figured they are all different so I didn't, but glad you bought these same tubes from the same seller and let me know this. How much do you want for the Mullard M8161?

You might want to PM me if you want to discuss tube prices; I shouldn't be proselytizing here in the first place lol...

 

Yup, different tubes, different burn-in time. The Voskhods (especially the ones you bought with gold grids and everything mil spec) are the most extreme example of burn-in time I've bumped into, along with my -also ultra mil-spec Russian- power tubes. I guess extreme tubes take extreme burn-in heh?

 

Most tubes will take 20-50h, and you should be able to get the "pattern" after 15-20 hours max, even though they might improve further. The voskhods will sound dramatically different before and after burn-in though, even I was surprised. They'll just become "good" suddenly over the last 10 hours after 100 and some hours, basically...

Fully agree with gibosi and Audiofanboy there. First thing would be triodes, at least my Mullard CV417 (6AQ4) is very upfront and quite bright. Then, the M1861 = CV4015 is quite bright, not as upfront but shamelessly straight. It was my favourite before we started all the new tubes. I am personally not a Voskhod fan. Although they sound good, the mids are not mine and I actually appreciated them better when they were new as they lost their sparkle after burn in. Remembering burning them in for 120 h...

+1 for that! I actually preferred both -very different- pairs of Voskhod tubes I had before burn-in. They were spiky all right, and quite unbearable on poorly recorded albums, but they had a presence that they lost after the looong burn-in. I remember being quite disappointed about that... Like "what the **** happened to my tubes!!!"

 

At one point, and since those tubes were so cheap, I almost thought about just buying a huge stash of them and only using them between 20 and 120h of use! Yeah... I was young and naive back then; now we're all rolling tubes that sound great after 20h and last up to 10k hours, that's progress for you!
