REVIEW SUMMARY: A ranking of 19 tube and tube/hybrid headphone amps
I have been asked repeatedly to do this, and I have resisted so far, but I have decided to go ahead and rank all of the tube amps that I have either formally reviewed, or that I have owned for a long time but not formally reviewed.
Note that this is a HUGE range in prices, from $6,000 to $120!!!! And note also that I ACTUALLY RECOMMEND and like EVERY ONE of these amps – understanding the strengths and weaknesses of each. So in some ways this should be looked at more just as a list than a ranking, although I did put them in order of my preference. I should also point out that, IMO, the amps ranked from #5 on down are all VERY close in terms of sound quality. From 6 up, some significant jumps begin to occur.
By request, I have included the price to the best of my ability. Prices are all in USD, and do not include shipping unless indicated.
Note also that I have not included on this list amps that I heard only at a "meet". This is not a long enough exposure for a proper evaluation. So in spite of my having been very impressed with amps such as the RSA Raptor and B-52, and the Eddie Current Zana Deux, since I have only heard these at meets, I cannot include them on a list like this. All of the amps on this list I had on loan for a full review, or I actually bought and owned for some period of time.
I have posted a link to all of my reviews. I hope this is helpful in some way.

Thanks once again for all your excellent work. I've said it before and it's worth repeating: the efforts of you and a small handful of other Head-fi review-giants make this site the wonderful experience it is for so many of us other mutts.
Regarding this line-up of hybrid amps, where would you put the Little Dot 1+? Anywhere? Nowhere? With all the clamour that amp received a few months ago, I'm a bit surprised to not see it listed here especially with the Quinpu getting a look-in.
Thanks,
Don

Thanks! I actually really wish I had ever heard any of the Little Dot amps, but I have not. Their absence from this list is a problem for sure, but I don't want to buy one just to review it, so I'm not sure that there will be a cure.

Awesome compendium and detailed as usual.
Very interesting to see where the PPX3 resides relative to the WooAudio 3+.
Thanks once again for your hard work saving countless people time and money not the mention making our hobby more enjoyable.
In Skylab We Trust.

Skylab I would love for you to review the Ming-Da MC-84C -07. I was skeptical about purchasing this, but I did after a glowing recommendation from you. You were absolutely right. I have about 100 hours burned in on this thing, and I'm very impressed so far. I would like to see if your impressions are similar to mine. Anyway thanks for recommending me this amp. There's not many people talking about this. So it maybe one of the best kept secrets on headfi. It can be had for as little as 350.00usd. Wow.

Yep, the MC-84C 07 is a very nice amp. I played it with my AKG K340s for Ray Samuels at a meet, and even he was impressed  . It does prefer high-impedance headphones, and good tubes for it are a little pricey, but with my all-Mullard tube complement, its an amazingly good amp.

Thanks! Yeah, "borrowing" tube amps is just risky business

Maybe someone should just ASK LD to send a selection of amps to our good friend Rob. He seems like such a nice bloke...

The Red Wine is some serious stuff. The Red Wine Signature amp is one of the best K1000 amps.

I really like the hybrid amps, even the inexpensive ones. When I saw the Red Wine at the top I was interested  ....for about one minute until I saw the price. I didnt expect a $6000 price tag .... ouch. Sure looks nice though.

Yep, seriously good, and seriously expensive. Of course for that price you do get an awesome DAC as well.

Please re-read the first post - I added a note that relates to (among others) the Zana Deux.

Very nice reviews. So the WA3+ is the least preferred; not surprising considering its price. And superb effort on compiling and linking to so many reviews. I read them all!
