Adelz said:I recently finished my Crack and want to try out some other tubes. What are the most reliable places to buy tubes online? Also, would something like a 5814A and 5998A be a good start? Having no experience with tube amps other than the Crack, I feel a little in the dark regarding how much of a difference I can expect from different tubes and what a reasonable amount to spend on a tube is (there appears to be a huge price range for seemingly similar tubes).

I added a dedicated DAC (Schiit Modi) instead of the Fiio E10 I was using and I have to say it feels cleaner. Only problem is prying myself away from the music
Thinking about ordering the 5998 from vacuumtubes.net
I highly recommend thetubestore.com, they are Canadian. Tubes arrived 2 days after I ordered them.
InXcesS said:Has anyone ever bought from vacuumtubes.net? I filled in an order form for a 5998 but it just leads to a confirmation page but nothing else, they didn't take payment details or send an email to confirm, should I be waiting for something?

One vote for the RCA Clear Top 12AU7 for HD600s. Any others?
John EH said:I have a Chatham 5998 and I for the life of me don't like it anymore. Although I do concur with you that for some reason the relatively low end RCA Clear Top is a perfect fit in the Crack circuit. That and the Mullard CV4003.
I put my 5998 in yesterday and tried to listen and I couldn't stand it. My Winged C Svetlana sounds better to my ears. My 5998 tests strong as well on my TV-7 tester.
Jimb0 said:What do you have in the input with the 5998's? The Winged C Svetlana sounds interesting. How can you compare them to the 5998's?
