Excellent Value Tube Buffer Bluetooth Streamer

Just received and connected to my Dynaco tube system. Very happy so far, easy pairing sounds great, I'll do some performance testing in a few days after the bulbs burn out a bit. This review and attached photos are of the TUBE-03 Mk II with built-in Bluetooth. I chose it because of the latest generation Bluetooth chip as well as the ESS D/A chip. Both are used in much more expensive Bluetooth streamers that do without a tube buffer stage. As such, it represents great value and the construction,

  • Home Audio

  • Expensive

Nice tube sound that won't hurt your wallet.

If you want tube sound, this might be for you. I was looking for a tube amp and initially decided to buy it as a preamp to see how my system sounds. Well I got a lot as it works great with my system and I got tube sound almost for free. Bluetooth works great. There's plenty of power for headphones, more than you need. I've used it primarily as a bluetooth preamp for my speakers and couldn't be happier. For the price it's more than ok, if you're looking for the best of the best hi-fi tube amps…

so far it's a clean sounding tube buffer

SNR: 100dB (higher is better) THD+N: 0.001% (lower is better) Look at the numbers above, this thing sounds very clean. I tried 5 different ones and this one wins. Always look at the signal-to-noise ratio (decibels) when purchasing Hi-Fi audio equipment. and total harmonic distortion THD % . THD indicates how much pure sound is lost in the device. 1.0% or 1% is terrible. 0.1% bad, 0.01% normal. 0.001% is very good. If you want really clear sound, buy a good USB DAC like the E30 with a THD of…

Pros
  • Preamp
Cons
  • Compatibility

Before deciding on this I bought four different tube preamps. All of them were from advanced Aiyima/FX/Fosi/etc. the family. They are all *very* similar, but each has a unique sonic/aesthetic quality. It has a great combination of a fully brushed aluminum body (front and sides), GE bulbs (which clearly sound better than the Chinese bulbs that came with others), Bluetooth with an unobtrusive antenna, warm and clear sound, and the dials are very beautiful the touch and movement good. The price…

Pros
  • Receiver and amplifier
Cons
  • Requires an outlet
