Swapping Psvane EL34 into Gold Lion KT77 tubes on an Old Chen AIQIN EL34 Single-ended Class A 10Wx2 amplifier & comparing it to a Fosi BT20A w/2xDual Sparkos op-amps Tube Source w/fast shipping: https://www.ebay.com/str/tonaltubes ************************************ So in case you didn't get everything from the title, I was upgrading my amplifiers and I thought you might like to see the process and hear what you can with my phone mic. The speakers are all on at once and are balanced (to the way I like them.) I have professional microphones that I will use if requested, but since I am just testing this out I am keeping it simple and unedited. Let me know if you want to see more technical things that I enjoy working on. I will do a kt88 swap on request. I have a Willsenton R800i 300b amp to show you in future videos. My intention is to have 4 of the best sounding amps for my living room optionally when I like a certain sound. I'll use a good class D power amp, like the Fosi bt20a w/sparkos op-amps, in case I want to turn the house into a nightclub but generally I will use a 300b, KT77 or KT88 at around 3 real watts (10 advertised) for room filling, but not ear splitting, sound from my Bose 901 resto-mods, super tweeters, Klipsch Reference series bookshelf speakers and matching powered subs on the passive out of the Fosi w/Sparkos upgrades. Source is a Zen signature series DAC or Zen Phono. I change the speaker connections and or use EQ to change the sound regularly. The main thing I was going for here was minimalism, second was versatility; and I was unwilling to sacrifice sound quality, but considered really budget friendly options wherever possible.

I could not understand why LDAC over bluetooth could not deliver perfect audio, but the biggest upgrade to my system was when he convinced me to use Tidal and a laptop and stop using my cell phone as a source no matter what the specs say... I listened and it's better for reasons I learned about afterwards and will not bore you with here. There are already great videos on that. I'm doing this for fun and to share w/friends.. if you are not both of those things then this video is not for you. "Be excellent to each other" -WS
