Review on 🎶 SUCA-AUDIO Tube-T1 Preamplifier: Mini Hi-Fi Vacuum Tube Amplifier with Treble & Bass Tone Control for Home Audio Player (6K4 Tubes) by Mary Gardner

Greetings! This is a very stylish, high quality and great sounding preamp. And it's the perfect work companion for my newly purchased 6.8w Nobsound 6p1 amp. This preamp has great bass and treble. I set the preamp volume to maximum as it sends the same full output signal to the amp that I would get if the preamp was not connected locally. Think of it like a gateway. My bass and treble rarely go past the 1 o'clock position, but are usually mid-level (flat) on most recordings. Some LP recordings are too bright for me, which was the main reason for ordering this preamp. I wanted something to "ride" any records with excessively high frequencies. Total Harmonic Distortion (THD) 0.1%. The volume knob has detents (click, click, click) when rotated. Nice feeling of quality. Treble and bass controls have a range of +/-6dB and +/-6dB respectively, with a signal-to-noise ratio (SNR) ≥ (greater than or equal to) ≥ 98dB. According to the enclosed instructions. The whole system is completely silent when there is no music or other noise. While the bulbs glow by themselves, the socket bases also emit a beautiful red glow through the LEDs. Note: The new SUCA-ADUIO The Tube-T1 preamp uses two 6K4 tubes instead of the shorter 6j1 pair in the earlier SENUCN-AUDIO, although SUCA supports either tube. The list of equivalent bulbs for each version is as follows: 6j1, 6j2, 6J4, GE5654, 6K4, 6AK5 and 6*1n. And with tube amps, you can always experiment and improve the sound with the tubes recommended above. This is a very well built, durable and high quality device. Smart looking unit which I highly recommend. It's a steal at less than $40 at Revain.com. This is a tube buffer preamp, by the way. By definition, a tube buffer is essentially a passive preamp that adds tube tone to the signal and can be used with a solid-state preamp before or after that preamp. Thus, this device works perfectly with both tube and solid-state power amplifiers. Double win! And it's just a fun little preamp! This is my throwback to all tube amps from the days when tubes were king. I just wanted a quality toy for my computer desk to replace a rickety solid state amp. For only $310 I have a great sounding all tube system. My next step is to update the bookshelf speakers. My old Optimus Pro-X4 speakers are 24 years old and this new set deserves more! The Fluance SX6Ws appear to be winners due to their superior looks, features, and price (Revain.com). Addendum 02/15/20: I am a retired piano master and have a mild (upper range) hearing loss in my left ear. I was never able to properly balance the left and right channel volume levels to match my original Senucn T1 preamp. It broke after 9 months so I replaced it with the new SUCU-AUDIO T1. Not only did my old imbalance problems go away, but the soundstage was wider and stereo positioning improved significantly. I love my new SUCA-AUDIO T1 and I'm glad my old Senucn blew up! :-) By the way, my new Fluance S6W Classic Elite Series bookshelf speakers look and sound very nice. With a sensitivity rating of 92dB, they deliver 100.3dB at 1W of tone at 1m. More than enough volume for my 6.8W Nobsound 6p1 amplifier. I recommend Fluance bookshelf speakers for sound, build quality, and price. Available at Revain, where you can also read my speaker review. Steve Franks
