Wow that looks amazing, maybe one day I may attempt to try this but I seriously lack the knowledge to take on such a project.   very impressive.

Is it possible to use an adapter so the little dot I+ can support tubes such as the 6SN7 or the like?

I have the OPA2107 but I've not tried that combo yet, I was thinking of getting the muses8820 or the 8920.

The EF91s are far better than the stock tubes, although find them very bassey which is perfect for my K550s but they don't pair well with the X2's. I think my favorite tubes so far are the 408As very clear mids and highs with recessed bass. Now just to try a few different opamps, I've heard a...

  Very Nice, here's what I'm rocking      

  I was tempted by the muses02 I found someone from china selling them for £5 on ebay I doubt they are real though. I find the sound difference in opamps lack luster compared to tubes, might pick up the muses01 one day if I find it cheap enough. :)

I'm using the LM4562 opamp and Philips Fidelio X2, I've not run them in properly yet but I believe I may prefer my Northern Electric NE-408A

  That did the trick thanks. :)

I just tried a pair of 6HM5s with the little dot i+ I believe the correct jumper configuration was the same as EF91 and EF92, I've tried the tubes and I am receiving no sound at all. Is this a sign of DOA tubes or have I opted for the wrong jumper configuration, I don't want to play around...

Hi Everyone,   I recently purchased a little dot i+  I've been playing around with different tubes and op-amps, I've been reading about using a adapter to allow for two single op-amps instead of the singular dual channel op-amp. What would be the benefits of using this setup, without any...

I just received my second set of tubes, Canadian made northern electric NE-408A. I'm very surprised what a difference they have made, it blows both the stock 6J1 and the EF91 CV3577 out the water. Using Philips Fidelio x2 I christened them with the track Elegia by new order, the first minute of...

  Thanks for the reply, this is terribly embarrassing, I bought this amp second hand, the jumpers for gain control were missing which the pins are soldered directly onto the circuit board. J1 and J2 have plastic at the bottom of the pins before they touch the circuit board. I mistook these...

  Hi gibosi,   Thanks for the reply, referring to the little dot i+ reference guide it says I should have both jumper J1 and J2 closed for EF91 tubes. On a second glance at the amp I've noticed the gain is currently running in an open circuit which is probably too high for my fidelio x2's I...

I mentioned earlier I was having issue with some EF91 tubes in my little dot i+ well the seller has sent me a second pair of tubes next day delivery. I'm trying them now and it's the same problem. The sound is very quiet I have to set my source to 100% and my little dot to 20% in order to get...

Appreciate the replies, The stock tubes are working just fine I believe they are the Chinese 6J1's, they are quite noisy tubes very susceptible to magnetic fields it would seem. When I get some time this weekend I'll try running the new tubes in for a few hours, hopefully I will hear some...

Hi Headfi-ers,   I've lurked for a few weeks and today I've joined the forum, I didn't want to spam the forum with a question that's most definitely been asked before however I'm struggling to find an appropriate answer. Last week I purchased a little dot i+ amplifier and yesterday I received...
