Littledot`s website claims the mkvi goes to 600 ohms. . . .  

 

Really, subjectively, anyone, what is the difference between these amps beyond price ?  Or maybe I should ask what, if any, reason is there to get the viii and not the vi ?  I`m driving hd800s. . . .

Still waiting.  Hasn't quite been 4 weeks yet.

 

In the meantime, I've installed these:  http://www.ebay.com/itm/271285052169

 

And these:  http://www.newegg.com/Product/Product.aspx?Item=N82E16835608006

 

It no longer sounds like a garbage disposal.  Those stock fans are complete $#!t.

Nice I got one of those as well! In my pc, and wait you installed a new fan in your Amp :O

I can't speak for the 800s, but I think the MKVI+ is a bit underpowered when trying to drive 650s.  That's with the amp on low gain and with the tubes mentioned earlier that everyone loves.  With a balanced DAC feeding it, anything higher than 85 just starts to sound...  Stressed?  Slightly distorted?  Not very good.  Flipping the switch to high gain introduces additional noise and overall doesn't sound that great.  I plug them into the Lyr sitting next to the MKVI+ and they sound like they should at the higher levels.  The WA6 I used to have had an even harder time with the 650s.

 

However, my 650s are just a few months old too.  This all may change after many more hours of listening.

There's two 80mm fans on the bottom cover.

 

4th post down:  http://www.head-fi.org/t/355165/little-dot-mkvi-has-arrived/45

 

I thought maybe some packaging material got stuck in the fan the first time I turned it on.  Nope, just really sh!tty fans.

Never got the chance to try them.  I sent the ATs off the day before the MKVI+ arrived, not knowing the MKVI+ was already in transit.

 

However, I think the MKVI+ won't have a problem at all with them.  Especially since the WA6 drove them with ease.

Dead silent.

I took my busted MKVI+ to a local reputable shop in San Jose yesterday. Originally thought it was just a bad fuse, but the shop owner thinks the power transformer malfunctioned as well. Looks like I'm biting the bullet and sending this one back to China for repair.

Aside from that, has anyone tried drilling holes into the top of the amp for ventilation? It seemed to us that there is no place for heat to escape with the standard enclosure. Wondering what good the fans even do under this assumption.

Thanks for any feedback.

Does yours not have the holes dotted around each of the six tube sockets?

Close to it.  And only on low gain.

There are holes around the tube sockets for the heat to escape. That roughly 60 holes on the top.
