Little Dot Tube Amps: Vacuum Tube Rolling Guide

Oh really ok thanks, have to see what other driver tubes are out there.
We have all rolled a tube or two in our amps to find the best... :wink:

My favorite tube for the past 7 years with my DT880s has been the Yugoslavian EI 6HM5 tall version.

The chances of getting a pair out of Serbia anytime soon might be quite difficult though.

To be honest, I don't regret that I have tried many other tubes in my Dotty. It's possible to elevate these amps to a higher level with a 'fuller' sound. Right now I am listening to one Sylvania 6SN7W and one Sylvania 7N7 as output tubes and the sound quality is much higher than with GE 5687 but so can the price be. (These two specimens are actually the same tube with different pinout and I have been lucky to find them for cheap). For inputs I use Sylvania 6C5GT which is slightly warmer than Ken-Rad 6C5.

Another way to reach the same SQ could be to buy a better amp...

Yeah you got a crazy amount of two and I can definitely get into tube rolling. I got to say my first roll with the ones I bought over the stock made quite a bit of difference not major but definitely noticeable and I'm going to listen to him closer let him get burned in and see if there's anything that I don't like about the sound.

But I'm still learning about where to set the gain because it comes on the lowest setting which I had to turn my amp up to 3:00 to get enough volume I've moved it up to the third setting which definitely made a difference but from what I hear each game is going to give you a little bit different sound so I may play with some of the other games and see what it does it just kind of sucks that the gain you have to open up the case.

It is a good idea to get to know the amp with cheap and easily available tubes before moving forward. Tubes also often needs to be used for quite a while before performing their best. Don't rush anything - take your time with incremental changes that you thoroughly evaluate before making next change...

Well i just got a new dac SMSL D300 and im playing with optical out of my computer soundcard to dac, or usb from computer and bypass computer soundcard and go directly usb into dac.

I will say im enjoying my amp and sound, one thing is it seems a little underpowered for my HD 650, im one setting below the max gain, i may try max gain but i hear people say it gets noisy, hissy, one wish is this thing had a little more kick.

Well im back again and after several days of listing i have to say this amp is under powered for HD 6xx just aint enough kick for me. Thinking about moving up to something more powerful. I love the sound but the kick aint there. Any suggestions of a stronger amp under 500 us dollars ?

My Little Dot MK IV puts out 500mW @ 300Ω and will push my DT880 (250Ω) too loud anywhere past 12:00 on the volume dial. I'm using a gain of 5 on the amp. The Mk 2 is only 300mW @ 300Ω and your HD6XX are actually easier to drive than the beyers.

Under $500 I would suggest the XDuoo TA-26, the Darkvoice 336SE or the Little Dot MK IV.

Thank you I was looking at the ta-26 to me that things ugly looking I wouldn't want that on my desktop but I've heard excellent things about it. I guess I could turn my little dot mark 2 up to the highest gain and see if that helps.

The Jotunheim 2 and a balanced cable (dont need a balanced dac for this) has really good slam.

I have a balanced DAC is that jottenheim a tube amp?
Oh no, sorry didn't realize that was a requirement. Not sure offhand, but anything that uses 6080/6as7 power tubes should give the effect you want. It might be hard to find under 500, though. Trolldragon's suggestions look good. Never tried an XDuoo Amp first hand, but I've seen good reviews.

Yeah Xduoo TA-26 cant find a bad review on it, hard for me to get past the looks of it. Im thinking Xduoo 26 spanks little dot mark ii. Wonder if the little dot tubes will work on Xduoo 26.

I agree - especially with the Xduoo TA-26 recommendation for the HD6XX (and other h/p with impedance of 250+ ohms).

No the tubes on the TA-26 are different.

Bummer about the tubes the tubes are non returnable so I'll have to put the money eBay.

Let me know if anybody's interested in some Russian tubes for this amp real cheap I'm getting rid of them.
