Two more:

• Coincident Dynamo MKIII (available on special order optimized for 300B output tubes instead of the EL 34 which is still standard)
• Transcendent Sound Masterpiece 300B Preamp/Headphone Amp

Despite it is discontinued, Fostex HP-V8 should also be included.

I have a pair of Western Electric 300B (2021 version) for my Little Dot LD-Y2 and a pair of Takatsuki TAK300B for HP-V8. The Takatsuki has amazing airy mid and high and perfect imaging, while the Western Electric is strong at low, sweet mid and excellent dynamics.

Transcendent Sound Masterpiece 300B Preamp/Headphone Amp added*
Re-added Fostex to 300B list.

Fostex HP-V8

I had it in the non-300B, didn't realize it took 300B! Impressive looking amp.

Manley Audio Labs Neo-Classic 300B pre owner

Is it great with headphones? or it is only amazing with speakers?

 

[kvik]

ADDED* Thanks....

Could not find the proper model for Sinus Audio?

@Haidar
You found a treasure chest!! Zeus almighty! This might take me a few days or weeks to sort through.

The Sinus amp is called OTL 300B, it's a sibling to OTL 2A3 ProAudio, it's not on his website, but there's a photo on his facebook page.

Added*
With 20 more amps

I can sort of understand the 300B interest, but what is the criteria for the non-300B entries? Wouldn't it be more interesting to sort everything into for instance directly/ndirectly heated; triode/pentode/tetrode; power/driver/rectifier; or sort by popular/well-known tubes like 300B/2A3/EL34/EL84/6080/KTxx/etc? Just stating name and price doesn’t provide much incentive to investigate further, at least not for me.

Something like this:

https://en.cayin.cn/features/8/57/73/369.html

I looked really hard at buying that listing over the HA-300Mk2 ... has 300B and 845A tubes in the same unit. Would have run to hp's via speaker taps.

@protoss do a list of 300B preamps for me please.

I have LD-Y2 and did two repairs already. Basically no warranty living in USA unless you can make the investment in shipping to China.

Two resistors blew and toggle switch burnt. Do all the fixings myself.

Is it great with headphones? or it is only amazing with speakers?

With both, definitely, it's just one of the amp's strongest features is the gargantuan and holographic soundstage, something that headphones struggle with compared to speakers. Regardless, the Manley is a reference performer regardless of what you're listening to.

what is the criteria for the non-300B entries?

I will use the Woo Audio WA33 as an example to explain.

I placed the WA33 as a 300B amp. Poster 1 explained that it was not a 300B amp. I had to recheck and found out it is in fact not a 300B amp. This surprised me and maybe to others too. So, to prevent future poster to repeat and ask me to put the WA33 as a 300B, I made a NON-300B list. This not only help us but give everyone an example of how many amplifiers there are and an idea of other companies. https://wooaudio.com/amplifiers/wa33

My primary goal is still for the hunt for 300B headphone amplifiers.

stating name and price doesn’t provide much incentive to investigate further, at least not for me

I am only 1 person. This is enough to tickle a person interest to further investigate their amps. With my list or our list, I already have 2 amplifiers I am ready to buy
