Absolute top tier DAC for standard res Redbook CD

Very true Andrew. One change can throw off a system so easy. A tube, wire, capacitor modifications and the like can dramatically change the music. Oh my, the amp speaker relationship so much more so.

I am now buying more music as I finally have great synergy in my room. Not just good at times, but satisfying over and over. Hard to find this sweet spot.

Now I have to be careful and not mess with it! Also hard to do:)

Sksos1, I admitt, I am afraid to go down what could be an endless Rabit hole of tube rolling!, I love my sound now!, however, I have followed Jafox's post about tubes, so Steve, what do you think about this? I have a 6z4 recetifier tube in the power supply that is vintage American, how or why this came stock in my vincent player is baffled me,it sounds great, the problem with that tube, there is no replacement for tube rolling, so I will have to go back with the same there, but following Jafox's tube exsperience on the threads, I learned from him that a good tube for the 12AU7 tube replacement is or could be the RCA 12BH7 Red Label tubes, or the 12BH7A Black plates tube, and I suppose the Telefunken 12AX7 tube for the 12AX7 tube replacement, unless any one has a better idea for the 12AX7 position?, Steve, I have incredible Bass and treble extention with the stock tubes now, I would be angry if I lost that part of the sound, I have read that some tubes can have you loose bass, My player has only one chinesse tube inside stock, the other tube that came in the player stock is a harmonix tube and then the American 6z4 tube that I do not know who made the tube?, cheers.

Hi Jafox, your last post is how I compaire audio, great recommendation your post is, but I have been doing this along time, and your post is how I do things, funny though, I really do not have much tube exsperience, so your knowledge is most welcome if you care to share?, Thankyou Jafox.

Matt, I appoligize for the off topic post here, However, If you do not mind, I wanted to take advantage of haveing alot of the Audiogon seasoned audiophile in one place!

Audiolabyrinth, why not start a thread here or at audiocirclce dealig with this?
I recently got some tube experience about this, for the 12xxx tubes, try the european ecc equivalents...ie phillips/ siemens/mullards/brimar/ Marconi/Tungsram(white labels) . Not Telefunken, which are clean but are dull.
Not electro harmonix, not JJ unless very old. Not any chinese either.
Unfortunately, some of the recommended tubes are expensive online, so be patient.

US tubes rule the roost for rectifiers and 45 triodes. PM me if you need more of my 2nd hand info. I learned all thus only this week doing a deep dive.
