Schiit Saga which tubes to order?

I should clarify.. a Russian 6N8S (NOS) is the stock tube for $349.00. The Tung-Sol 6SN7 is available at $374.00 and both the Tung-Sol 6SN7 and the LISST is available for $414.00.

I appreciate the feedback. I’m trying to determine wether to buy the upgraded tube packages with my Saga; or just buy the stock tube that is included from Schiit for $349.00

Marco1 thanks for your response. Since you have a Schiit Freya you understand the question I was asking. I don't think I did a very good job of articulating what I was wanting to know. I think I'll order the stock tube. Then I'll order the Early Russian from Upscale. Have you enjoyed the Freya?

Which DAC did you buy?
Lowrider57 thanks for the tube guide.

Low rider I appreciate it. I’m a newbie and am getting an education.

My Schiit Saga came in the mail today and after several hours of listening, I am extremely pleased. I had been using My NAD C326bee’s preamp section with my Nuforce sta200.
What a difference! It sounded like a vale had been lifted from my Zu Omen’s. There wasn’t a huge difference between the passive and active preamp, but I plan to buy the Early Russian 6H8C from Upscale audio in my search for a tad more warmth. What a great little preamp for $350.00. My next step is to upgrade my Peachtree Dac-itI and some interconnects. I appreciate and welcome all  comments! Thanks again!

Thanks lowrider57.It ads a touch of warmth. It will be interesting to note if it sounds different in a couple of days.
