Can someone explain what that means exactly?  If the tube is part of the usb dac functioning does that mean the tube has nothing to do with the headphone amp?  I want to purchase one of these to use with my headphones and eventually will use the dac to connect a pair of krk rokit 5's.  I know that'll be fine because the krk's are powered, but will the tube limit what I can use on the t1's output line?

The T1 is a DAC with Tube buffer that feeds into a headphone amp. If you use the line in only, then the Tube does not come into play. The tube is not part of the amplification signal path.

I guess I have to eat a few of my words now after recieving the Voskhod 6N23P tube and doing som more listening. I certanly can hear the difference in sound, but like Blues Daddy says it's subtle. This is like wine tasting actually. I'll have to learn it by trying. I will be careful to point out what the differences are yet, but I have to correct myself about the openness/soundstage in the Phillips PCC189. And like I learned form Salvatore, listen to one thing at the time while doing A/B rolls makes it easier to hear the difference.

 

In my terms I find that the 6N23P is more "fun" to listen to, and the PCC189, in some genres of music, more relaxing to listen to. Looking forward to learn more :)

Yes that's how it is. There are definitely differences, but they can be very subtle indeed. Sometimes I hear the differences very clearly and sometimes everything sounds the same. I've learned that you don't want to do critical listening if a) sick or b) tired. You might also want to listen one tube for a while before rolling. This way your brain gets used to the sound and the differences could be a lot easier to observe. Oh and maybe you should try combining tube rolling with wine tasting. Some tubes might go better with certain wines. At least it's fun with special beers, lol biggrin.gif

Last week was probably not my best then. I was beginning to get sick and had my head full at work. I was actually home sick saturday throug tuesday this week..

 

I'll guess that combining vine tasting and tube rolling will go in favor of the last tube tested regardless of which it is :)

Okay so can I still use the rca out to a pair of monitors while using the dac with usb?  If so can I use my headphones and monitors at the same time while on usb setting, or will one override the other?  If so I guess I could just unplug whichever I'm not using?  Really I'm only going to be using the usb setting on this dac/amp.

You can use both the headphone out and the line out at once. I just tried it out. Had my DT880s plugged into O2 via lineout and plugged in DT770s into the T1's hp out. Both were outputting.

Very nice, I can't wait to get mine now!

So I bit on one of those cheapo T1s on eBay. We shall see what we shall see. Assuming it's legit, what should I be looking at for my first couple tubes and where should I be procuring them?

All my relabeled tubes have markings on them. I have a Zaerix with Mullard markings, two RCA's with Siemens markings and a RCA that has the Phillips factory code on them and a RCA 6922 that has the USA AMmperex markings/dates on them. I was under the impression that the tubes were made, then restamped with label markings.

Does anyone else's T1 get burning hot to the touch?

It does get hot but not to the extent of scalding. Tubes do warm up a lot, but that's just how they work. They're like mini light bulbs.

My T1 eh 6922 tube gets really hot, but not quite burning..  the amp itself doesn't get hot at all.. it's barely warm.. I use it at 0db gain though
