I recently got a xduoo TA-20 and I love it. I want to upgrade to the TA-20 Plus and see if that power tube helps.

Wow that is not suppose to happen it is suppose to be out in over a week from now.  I wish I was in your shoes cause I've been waiting for them since CES.  Will definity be passing by my local best buy tomorrow in hope that they have them too.

So the ressonessence labs website is down. And I accidentally deleted the drives needed to use my concero.  If anyone has the software to share I will be grateful.  Or if anyone knows if the website will be coming up anytime soon.  My entire set up is useless without the dac currently :(

I love solid state drives. Can't go back to old hhd.

I personally would love to see the perfectwave in here.  As a owner of the a concero.  I'd love to see how it would stack up.

Ive listened to a few vinyl setups with headphones that run around 3k-5k and one actual speaker set up.  Your right that the lowest hz are emp/body shaking/ambiance. I even own a few records from my favorite albums just to decorate the walls. And personally I won't recommend a CD setup either...

If you throw enough money at it a lot of vinyls noise factors are cut dramatically.  It ends up being that some people prefer vinyl because of its lush sound signature. That 80hz cut off ends up not being so bad when you remember that due to age you probably can't hear 20hz or 30hz, and...

I agree I think it is this thread that pulls in the younger crowd.  While lets say threads on summit-fi pulls in a older crowd.  I am 19 years old.

Remember you can get the speedball upgrade when ever you want.  Personally I would invest in upgrading the stock tubes by just putting in $40ish bucks.  Then worry about the speedball then worrying about upgrading the dac. 

My vote is to keep the schiit.

Sad to see the company is called line5  which seems like a bootleg of line6 even sharing the same logo style.

 Comfort is a big part of why it was ahead.  With artist to artist it goes in favor of one or the other.  To me the hd650's won some of my favorite artist so that is why it is number 1).  I am currently saving up for some hd800's but I wont get them till the summer.

I actually have to change my answer to BenF.  The dac's I mentioned use a lower level chip compared to what BenF recommended.
