Shootout of Nos 6sn7 tubes
Someone tipped me about the manufacturing date on the etched note of the tube.The 1578 that I got was made in 1980.The 1578 that I got was made in 1983 not 70's.8n6s Nos tube was made in 12/78. Even without 1578 notation, some tubes are still p...

LuismaWhat you got is just regular Melz 6n8s tube.Melz 1578 is notation for quality certification for military use and nuclear plant. 
Jadis ja-200 vs ja500
I had used Jadis 500 from 2000 to 2002 to drive B&W Notilus 800.It gave the most powerful and deep bass in my listening room.But I could not tolerate too much heat in the modest size listening room.Thus I let it go.No experience of JA 200.Now ...

@luismaSorry to  hear your bad experience.But I think you did not get Melz 1578 at 10$ per tube.Melz1578 is a special one which cost 100$ per tube or more.I am enjoying Grieg Piano Concerto  through Melz 1578 now.I can definitely claim this is the... 
What to replace an Adcom amp with?
Used Rogue Cronus Magnum II can be had around 1600$.If you spend around 300$ to get Nos Amperex or Mullard 12 Au7 and ax7, then it will sound very good.Rogue does not sound like classic tube amp but has good control for bass and more refined trebl...

It depends your room size and genre of music you prefer and how loud you play music.Sometimes WAF also matters.Most wife does not like Tekton Design speaker which looks ugly like coffin.If OP give more details, I am willing to give my opinion too.... 
Schiit Freya+ vs. high end (e.g., Mcintosh) ?
@ hickamore One person claimed that using 300$ Melz 1578 at gain stage and 600$ TS bgrp at buffer stage in Freya+, he got the utmost sound out of it.My Melz 1578 is staying in Line Magnetic 508, but I may try to duplicate his method.It is best to ... 
Lyngdorf 2170 + 2400 Bi-wired
Crown XLS 2502 has also small footprint.When I use it to drive power hungry Raal Sr1a headphone, I got impressed with speed and clean treble.Now I am using two XLS2502  bridged to drive two Scaena 18 inch subwoofers.Thus I recommend Crown instead ...

1578 tube made in 1970's will be delivered next Wednesday.I will find out!But it is possible that tube made in 80's work better with my system. 
Top 10 epic audio items in my audio history.
Thanks ebm for your kind word.With 1578 tube (250$), it sounds so musical and dynamic, I like system.Most people think it is crazy to include 250$ Nos tube in Epic things.

Lyngdorf 2170 + 2400 Bi-wired
As Lyngdorf 2170 owner I recommend this.Use speaker output of 2170 for high frequency.2170 has high pass function to adjust crossover point if you go through the manual.You do not need to get 2400 but I recommend Crown XLS 2502 which can be fed th... 
Schiit Freya+ vs. high end (e.g., Mcintosh) ?
Freya+ sound decent with stock JJ tubes.It does not sound etched before break but slightly veiled compared with Nos tubes.You can get nice Nos 6sn7 tubes made in 1950's at 50% for pair.I like the remote of Freya+ with click noise while some people...
