Cayin HA-3A, a Compact 6V6s Transformer-coupled Tube Amplifier
Ultron5 actually has no Telefunken or Gold Lion tubes, only the stock ones. He just quoted TheAbyss2022.- DrDen

I see the sticker “Burn in…”, so you should hear the difference right off the box. Really interesting how do these compare to Reflectors.- DrDen

Cayin HA-300MK2 (2022) TOTL Transformer coupled Direct Heated Triode Tube HeadAmp (Page 91)
Mine were bought on AliExpress from China, no warranty period (at least as far as I know). I bought them from seller who sold me tubes before, replacing defective tube with another one, perfectly matched. Of course, WE300b should last longer, but it costs 3 times more here, and warranty is quite...- DrDen

Great to hear you like Acme 300b so much! I’m absolutely in love with my current tube combo. The latest addition was 6su7gty (many thanks to Jamato8 for recommendation). Violin sounds piercing in a good way, as it should. Bass is great. Please everyone take in account my speaker amp isn’t HA300...- DrDen

You better get used to the sound with stock tubes, while burning in you can read the thread from the beginning. No one can recommend you other tubes until you realised what you want.- DrDen

Totally agree with you about the importance of clean power for hi-fi. Thank you for reminding me about Puritan. After brief reading I have ordered the PSM156. Costly, but I have no idea what else to improve (for reasonable money). Will see if it can solve some minor issues with my tube amps...- DrDen

Again, I think it’s not the thing you need first. Someday you will try some, and if you hear improvement then it works for you. I have only basic and affordable power accessories.- DrDen

Well, this noise meter seems to be very useful thing :) IMO power conditioner isn’t mandatory unless your mains is problematic (noise, unstable voltage, DC offset). Since you are okay with your SS gear, probably it would be the same with the HA-3A (tube gear is more sensitive to EMI though).- DrDen

I have to mention that powering the audio gear from different outlets may cause ground loops. HA-3A isn’t that power hungry to be necessarily fed from dedicated outlet. Anyway you definitely should try this amp. Even with stock tubes it will be a real step up for you (just the way it was for me).- DrDen

Just got the inexpensive Gustard 1,6A fuse (ceramic, sand filled), but haven’t inserted it yet (rarely listen to headphones). Stock fuse is 1,0A, but the difference isn’t that big. I’m using these fuses in the rest of my gear (3,15 and 0,63A) and feeling no need for upgrade so far.- DrDen

As far as I know the headphone amplifiers built in budget tube speaker amps are usually just SS small circuits. MT-45 internals look different though, but dedicated SE headphone amp seems to be superior for sure.- DrDen

Actually no matter what do you listen to, speakers or headphones, the good DAC is essential. I’m using my DAC with the speaker amp via RCA, and the headphone amp via XLR. Enjoying them both.- DrDen

Given the lack of information about Lampizator it’s really hard to answer. As both pieces allow tube rolling, you probably can eventually find the result you want. Too many variables in this equation.- DrDen
