Tube heads let see what you say

I may have just acquired a Dared SL2000a. The seller has stated the tubes are new ( less that 2hrs. on them), but like anything else there are tubes to chase.
Two questions
1. What have you found to be the most musical 12AT7 tube to use and why.
2. Which rectifier have you used in the 5Z4 group that is just stellar and which to stay away from?
For now the seller has 2 Mullard 12at7 (m8162) and a 1970's Brimar CV1863 5Z4G rectifier
any 12at7 equivalents I should also be on the look out for ?
I've used a ton of 6sn7 tubes so I'm getting my learn on for these new tubes.

HT - Polk 703's * NAD T-758 * Adcom 5503 * Oppo 103 * Samsung 60" series 8 LCD
- Telefunken 5965 - great detail, tight bass, H9's "Holy Grail" (see thread https://forum.polkaudio.com/discussion/117770/holy-grail )
- '59/'60 Amperex Bugle Boy ECC81 - Long arm "D" getter w/foil strip - made in Holland (bt from H9) tight bass, lovely mids, probably expensive (codes would be critical in confirming legitimacy if not buying from trusted seller)
- Mullard ECC81 - warmer sweeter tone, looser bass, liquid, musical, gooey-in-a-good-way
- Raytheon 6414 - I remember really liking these, but I don't have any notes on them and they're in storage
- Brimar 5Z4G - pretty sure I used both brown and black base, recall slight preference for brown but may have have been due to other factors (different Dareds, signal tubes)
- Mullard 5Z4G - remember this as almost as good as Brimar but don't see any notes
- Tungsram 5Z4G - remember liking, but the one I used had very little life left
For good reading on Dared tubes, start with Holy Grail thread and maybe look at other H9 tube threads and comments. He had the SL-2000 (among other Dareds) for a long time, has tested a gazillion tubes, and has a deep knowledge of NOS tubes.

The Dared should be here tomorrow. Hopefully it was packed well and FedEx handled it carefully as well.
Ok so the Dared SL2000a arrived as of 15min. ago.
First impression are HOLY SHIITE!
This thing drives the the Aragon 4004mk2 like a stolen Vette.

yea Don I'm all ears. I'm new to these tubes 6sn7 is my knowledge base. Yes I'd like to be able to roll tubes and a couple of rectifier's just to kind of get my bearings on these tube types. At the same time I do not want to waste time and money on those tubes that others found distasteful IF you know what I mean. Some good outstanding tubes to roll to see what jives with my ears and gear.

Thanks Mikey
Josh I have not had time to really sit and listen. Too many outdoor stuff to do today.
I'll get into it but I will say it really drives to Aragon. The Adcom 565 pre did a good job no complaints except that it may of been a little low on the output side since there were many times i was past 12 o'clock on the volume knob. The Aragon never broke a sweat. The Dared well i was at 9 o'clock on the volume at it was VERY VERY LOUD and I thought the drivers were going to jump off the 2.3tls.
Tubes man need some tubes to roll. I just bought a pair of these for 70.00 for the pair. The seller sent me a special offer after they were in my cart for a day. Maybe the others will do the same.

So we will see I'm looking at others and have two sets in my cart.
Anybody else have some good tubes reach out.
Well if you want to thin the tube herd let me know. I'm not for from you. I can maybe take a few off your hands if you'd like.
thanks Bruce
Yep I'm enjoying it. Just ordered 2 early 50's Brimar 5z4g foil getter rectifiers. Brand new never used seller has a case of them. I thought he was pricey but he made me an offer on 2 shipped from down under. I had to give them a try for the price he shot me. Between the Sylvania 12at7 triple mica from you and a Raytheon 6414 I picked up too close to call.
I'm digging it.
