Tannoy Turnberry vs Fyne 502SP?
Like Jim Smith, my main stereo speakers are Fyne F703s. Best sound I've had in my home. I've owned a number of more expensive speakers in the past. Weiss DAC, Zesto electronics, SME table.

Experience with Puritan Audio 136 Purifier
Most audiophiles will not be able to tell the difference. Recently, the US distributor increased the price of the 136 from $1600 to $1800 but the 156 remains the same at $2300. With that in mind, an extra $500 (of course, less if discounted) is a... 
Experience with Puritan Audio 136 Purifier
My experience as well with both the 136 and 156.  
I've purchased several. Never a problem. But then, I have the capability to test, modify and repair if necessary.  
Tubes for a pre stage... matched NEW or unmatched identical NOS?
It depends on the circuit design. In most cases, no, you don't need matched pairs or matched triodes within the each tube. Honest tube dealers like Jim McShane will say the same thing.  
Even thought you can specify what DC voltage you want when ordering, there is trim pot inside that you can set to any voltage you want between 5Vdc and 24Vdc. 50W DC Regulated Power Supply

Duelund speaker cable
You're welcome. Yes I did on ATC SCM40 speakers among others. I used DCA16GA for all three. I'm just speculating the DCA12GA would be slightly better on the woofers. BTW, Jim Smith of Get Better Sound uses DCA12GA speaker cable, which he prefers ...

Most folks with a R26 find that it sounds the best with the LAN connection. There is a huge thread over on head-fi: Head-Fi Gustard R26 Thread and an interesting master clock thread: Head-Fi Master Clock Thread

@soix is correct. It's rarely mentioned in these discussions that I2s specs say no longer than a 10cm (~4 inches) cable.

A friend of mine is an integrated circuit designer specializing in network products for decades. I asked and was told that the main thing that happens when chaining switches is that you add latency (bad). So the sound probably changes. One of thes... 
ifi iPhono 3 "Black Label" Anyone?
@reidcc In your case, having owned both, properly broken-in, I would strongly recommend the Zen Phono with iPower X power supply. You have an excellent cartridge which, I suspect, you have no idea how good it can sound. The above mentioned combo w...
