Question on Emm labs Dac6 vs Dac6e


I am considering to purchase a pre-owned Meitner separate, very much confused for the models, especially some has Dac6, some Dac6e, I know the latest are DAC 6e SE, can anyone tell me what is difference between Dac6 and 6e, is it significant as 6e to 6eSE?

I don't see a fan outlet at the back panel of the Dac6, is it just a small fan inside the unit like what we have on a computer cpu?
Unless your heart is set on EMM, you may also want to have a look at the new single box Playback Designs MPS-5. Fellow audiogoner DCSTEP, oneobgin, and mikelavigne have commented extensively on its sound qualitys. The latter 2 preferred it over their own EMM multi-box rigs and have replaced their EMM with brand new MPS-5s. . . . at a fraction of the cost of EMM rigs.
Here is a review by Mike Lavigne:

In mid September I will have the opportunity of comparing directly the MPS-5 with a TEAC P03/D03/G0s combo and a DCS Puccini stack. G.
Guidocorona - I too have heard great things about the MPS-5 and read Mike Lavigne's review. But I question your comment about the price of the MPS unit being a fraction of the EMM labs rigs. I think I recall seeing "used" EMM labs rigs selling for $6 to $8K vs. the MPS-5 which has an introductory price of approx. $10K, but soon to increase to $15K. Please set me straight if my assumptions are innaccurate.
