those are good tubes but a lot of people aren't crazy about them. To me the highs are to piercing . Better can be had for less. E188ccs and even Cca s sometimes, For what you generally have to pay for the best Russian tubes. Rob seems like a good guy. He has a lot of great gear. None of that means he has the same listening tastes as you.

Thanks for confirming.... I purchased those as well to use with my ordered MJ2 .. I'm hoping it is sent out soon

I've been waiting for over two months

  Has anyone tried Amperex 7308 tubes?
 
rb2013 rates the Amperex 7308 highly in his tube review. Actually 2 different 60's vintage Amperex 7308 tubes make his top ten.
 
Upscale Audio has 1960's Amperex 7308's for $129 each (platinum grade).

I have both his 7308's and e88cc's. They sound very good. to me.

I agree.

Do you guys use the stock power cable that comes with Mjolnir 2, or an aftermarket one?

I know this topic is controversial, but I thought I'd ask.

I agree.

Thanks. How would you compare the Amperex 7308's to the iFi NOS 5670's?
 
Uncle Kev at Upscale describes the 7308's as "Ever so slightly relaxed on top. Liquid, smooth midband. Fabulous, slightly full bass."
Elsewhere on the site he refers to their warmth ...

Thanks very much. It's startling how expensive some of the rare tubes can be.

Thanks very much. Which E88CC's? I've also been looking at the Telefunken E88CC's but they run over $400/pair for Platinum Grade.

Going to be my first time tube rolling here. I think I might have purchased a few too many matched tube sets. I guess I'm pretty well set for a very very long time (see below)
 
Also, I have a Gumby. What way do you all connect your computers to your Gumby? I'm using USB into a Wyrd and then balanced between the Gumby and a Liquid Carbon --> waiting for MJ2 to come.

In my MJ2 I would say the 5670's are not as warm as the 7308's, a bit dryer more analytical sound than the 7308's. Both pair are very quiet, noise free, and I'm happy listening with either.

Anyone know of a cheaper XLR Balanced Stereo A/B switch?
 
http://www.goldpt.com/sw2x.html     The model: SW2X-O looks like the perfect fit but it's a bit high in price

IMO aftermarket cords are mostly in the realm of tiny improvements where you are trying to do everything you can to get the very best sound.
 
There are affordable aftermarket cords; I'm using an aftermarket cord for my Mjolnir 2 from Signal Cable ($69 for 3').
 
Signal Cable also offers a very competitively priced digital cord ($79 for 3') which I use on both my Gungnir MB and Bryston BUC-1 USB to S/PDIF convertor.
 
I use a Furman PST8D conditioner which has separate outlets for analog and digital sources.

Wow that's a lot of tube goodness. I'm salivating. I hope there's a pair there that you fall in love with!
 
I'm using a Bryston BUC-1 USB to s/PDIF convertor which afforded noticeable improvements in clarity and soundstage vs a Schiit Wyrd, via both Coaxial and BNC.
 
The Wyrd is capable device and I use one to decrapify the USB feed to my Bifrost 4490 in the office at work but swapping out the Wyrd for the BUC-1 took my Gungnir MB + Mjolnir 2 to a whole other level. Bryston put a lot of thought into the linear power supply for the BUC-1 and its outputs are also galvanically isolated.
 
There I go talking about power again ......

I was lucky as I was able to figure out the tubes I liked when I had my Vali 2. Buying one matched triode tube is easier and obviously cheaper than buying a pair of tubes with matched triodes. Unfortunately, I ended up finding that I liked Siemens and Telefunken CCa tubes. I also like the 1975 Reflektor 6N23P SWGP Silver Shields tubes as well. I have three sets of Siemens CCa tubes, one set of Telefunken CCa tubes, and three sets of 1975 Reflektor tubes. I am rolling with a set of 1975 Reflektor tubes in my Lyr 2 right now. I sure hope all these tubes sound the same or better in my Mjolnir 2 when it arrives!
 
I have set of XLR interconnects to connect my Yggdrasil to the Mjolnir 2 and XLR headphone cables for my HD 650 headphones coming on Monday. Now I just need Schiit to send out my Mjolnir 2!
