I want to ask about deutsche grammophon's new lp vinyl.
I’ve got quite a few OEM DG LPs that I bought new in the 70s. All analog, and many of them could make your ears bleed. 
What is it about spinning vinyl?
Maybe you should take up smoking until your Cosmos arrives. Now there’s a habit former. 
Do small preamp tubes 12ax7 need to be matched?
It might be that in the case Chakster cites, the tube is used as a cathode follower. Or a phase splitter.

Thanks, Raul. I knew you had experience with those things. 
Do small preamp tubes 12ax7 need to be matched?
You can "use" a 12AT7 to replace a 12AX7, in that the pin connections of the two tube types are identical, but that would be far from ideal.  The 12AT7 has less gain, a lower plate resistance, and a higher transconductance compared to a 12AX7.  In...

I think they were pretty good when on the market. But now they’re old and prone to lose vacuum due to air leaks in the system. Given your observations I’d worry about that. If you could localize the leak, you may be able to effect a repair.

Neon, it seems you have anxiety about repairing a cartridge that at the moment sounds “glorious”. Unless something has changed since you initiated this thread. If not, why not just relax and enjoy?Factoid: two years ago while cartridge shopping in...

Who said VTA adjustment was unimportant or makes no significant difference?Mijo, you’re thinking of SRA, not VTA, when you mentioned 92 degrees. I’m sure that was just a mental typo. Me, I never have even tried to visualize SRA. I just set VTA so ...

Blackbird 12.5" Tonearm: revised with DIN Connector.
Elliot, You figured it out. To strip those very thin gauge Litz wires, best to either scrape off the insulation with an exacto knife or burn it off with solder. I do the latter. However, if the Litz wires are silver, there is a risk of melting the...

Yet another vote for the Kuzma, among those on your list. I did have extensive experience with the Well Tempered Reference and its tonearm, when it was owned by a close friend who developed dementia in his last years. Thus I was doing the work for...

Hard to avoid LPs with at least one digitized step in their production these days. And many sound great. Judge by the quality of the final product is my advice. 
Origin live Cartridge Enabler - a review
elmo and hifi, It would be informative to know what cartridge(s) you are using with the Enabler, because cartridge compliance can have a lot to do with the results achieved, up or down. 
Origin live Cartridge Enabler - a review
tomic nailed it better than I did, on the subject of increasing the effective mass of your tonearm.  I should have noted, as he suggested, that the closer you are to the headshell directly over the cantilever, the more the added mass adds to "effe... 
Blackbird 12.5" Tonearm: revised with DIN Connector.
Those UNsoldered Litz wire leads provide an opportunity to run an interconnect direct to the phono stage inputs without a DIN plug in between. Or even to use a balanced connection direct from the cartridge if the phono stage is balanced.
