I'm a recent newbie to this too.

1) Decide whether you want a 6L6, 6V6, EL34, or EL84 (or even SS) power amp character. Lately I've been getting into the chimey EL84's. (also whether you want a single-ended sound).
2) Decide on preamp tones needed, and whether you need channel-swtiching.

Then you can choose a kit or design.

Be aware beforehand that this is a way to get very high quality and get what you want and have something flexible and re-configurable. It is often not a way to get it cheaper. A Ceriatone EL84 amp will have big durable high-quality pots and good transformers, sound great and last a long time. But you can pick up a used Peavey Classic head much cheaper. If you have a lot of parts handy, that's a different story. I like kits because I hate making a list and ordering, dealing with backorders, etc. On the other hand, next time I want to use 3 chassis: 1) power supply to mount low 2) power amp to mount chassis-down/tubes up, 3) preamp & reverb with controls convenient.

So what do you lust for? Go to a good boutique store on a rainy day when nobody is out, and try some. If you know you want a Matchless or Vox AC30, for instance, that makes it easier to choose a kit.

say you have a 4x12 loaded with the gbs at 103db more like 105-6db coming out all together with 1 watt.... I don't know about you guys but I think 120ish db is getting up there and starts the point to where it and everything above it is Fing loud lol. its tonal bliss though lol

Unmiked? Outdoors with a bandshell maybe. For a pool party at home maybe. Yes, speaker efficiency helps. But outdoors an open back cabinet doesn't help, unless there's half the audience behind you, and closed-back cabinets are going to be less efficient. Outdoors in an open field with amps facing forward the other side of the band often can't even hear you to play together. Depends on the noise of the venue, crowd, area etc. too. For a rock show you're not going to get very far with the volume of a spherical wavefront going down with the square of the distance. Some of the problem can often be handled with an extension cabinet rather than more power, so at least the band can play together and the near audience get a nice direct stage mix too. But nowadays even a lot of small bar bands mic everything. I have (but not necessarily use) 15,000 watts tri-amped for my home stereo in 2-channel mode so I'm the wrong guy to ask.

that's exactly what I think of with el84s is a wild top end chime, it sounds quite a bit different than all the others to my ears. Just a chime, while I would describe most 6v6 as sweet on the top end if not slightly piercing. but 6v6 are crazy because of the different characters. the RCAs have a really nice defined lows and a more smeared mid range to me, the sylvania's are pretty bright but they have this interesting mid/upper mid snap/zing thing that the RCAs I had were lacking in. the GEs were really different, tight lows, the mids were really detailed but the highs were quite a bit more laid back. the JJ 6v6 kinda reminded me of an RCA but more sterile sounding lol. A lot guys would love the JJ though because of that 6l6 like low end wahhh/warble thing lol, it was too harsh on the high end to me though.

If a 4X12 is loud at 50 meters, its because it's beaming straight like a laser and you'll need one on each side of the stage or outdoors with no room reinforcement or the rest of the band won't be able to play along unless your backline is way behind the whole band and pointed across.

I don't even know what kid of 6V6 are in my champ. I'm still learning its essential character but I like that it has no tone control just 2 volume (one early, one late). And I already lust for parallel single-ended more than for another gain stage.

But...what does the orignal poster dream of?

I don't know maybe I perceive loudness quite a bit lower than other people, wish I could hear stuff through other peoples ears lol. my ears are very sensitive I can pick up a 3db change easy I swear I think I can pick up like a 2db change sometimes. but for someone that doesn't have a trained ear whats the threshold or level when they start really noticing a difference 6-7db? or even 10db?..... that sounds crazy to me lol...so like you would hear something then you would hear something totally different would it be twice as loud or twice as quiet? lol
