Well, the Jinro/Tomei/Ongaku are all great amps - and the Meishu Tonmeister and P3 Tonmeister may be the best 300B amps around - certainly the best I have heard. But they only come with stock readily available tubes. Many other smaller boutique brands that only sell a handful of amplifiers a year will often sell with top-of-the-shelf sounding NOS tubes that cost a lot to replace. So often the comparisons are not exactly equal - AN with their $300 300b from China VS amp B with their $4000 a pair WE tubes is not apples to apples.
You might think this is simple is the Jinro better than the Meishu but the Jinro is around triple the price and has no phono stage or truly active preamp on board (it can be used as a power amp and the volume control as a secondary attenuator (like the P3 Tonmeister). The Meishu as a modified M2 preamp stage on board which makes it separates in one box).
I am in a similar predicament - I love the sound of the Meishu Tonmeister but I already own the M6 and Empress Silver monoblocks (2a3) level 3. I am currently reviewing the P3 Tonmeister. The Jinro being a 211 sounds better IMO with the M6 feeding in than it does on its own. That's my issue with the Jinro - it sounds better to me with an active preamp so the Jinro is now way more expensive than a Tonmeister AND you need an M3 or M5 or M6 to really get the most out of it. So now you're pushing like 6 times the price of the Meishu.
What you may not know is that Audio Note has just released two new 300B integrated amps above the Meishu - a level 4 Konzertmeister which uses a modified M6 Phono stage (this would be equivalent to the Tomei 211) and a level 5 version Kappelmeister (M8 Phono stage) which would be the 300B equivalent of the Ongaku.
I am considering either a move from my M6/Empress to Konzertmeister or trading my Empress monoblocks for a P3 Konzertmeister. The Empress is great but it is a slight preference for what I perceive to be more warmth and body from the Tonmeister Galahad power supply than the leaner parallel 2a3 sound.
The Jinro 211 is more robust - it is a more powerful amplifier but like all of these tubes - I have found that each of the tube types offers a sound the others don't quite muster. Take the Paladin - this is their 45 - it has a kind of sound that is beguiling - it is relatively affordable in AN land - it is also level 3 but it has that somethin somethin I like more than the other amps they make. But at 2 watts - it is hampered in some ways (umm volume/headroom) but it's also worth a listen. I am trying to get one in to try.
Anyway for the ultimate in AN discussions with plenty of owners and dealers - try here
