The Love Riverside from 300B Tube Amplifier plus IWISTAO 6.5 inches full range labyrinth speaker

The Love Riverside from 300B Tube Amplifier plus IWISTAO 6.5 inches full range labyrinth speaker

The Cantonese song "The Love Riverside" from 300B tube power amplifier + CD player + passive preamplifier + IWISTAO 6.5 inches full range labyrinth speaker.




This 300B single-ended tube amplifier adopts the famous Audionote circuit. Its power transformer carefully wounded by British Red Bull iron core. The advanced HI-FI design without large loop feedback makes the sound delicate and lingering, and rich musical.

 And, The 300B single-ended output transformer uses British amorphous high-grade C-type iron core that has a unique advantage, especially when he static operating point is 80ma or below , it can give full play to the advantages of the output transformer. After actual measurement and listening, the voice is very vivid, clear, low-frequency tension is very balanced in three bands, excellent permeability and atmosphere feeling. Using high-quality enameled wire, lamination process, CNC drying, vacuum impregnation, well-designed 8C structure, to design to a perfect coefficient.

Passive preamplifier is made of GEC 48A original authentic 600:600 input transformers (second-hand disassembled one) ,which oscilloscope test bandwidth 20-20KHz;

See who's singing from Tube Preamplifier + IWISTAO 6P1 Tube Amplifier

See who's singing from Tube Preamplifier  + IWISTAO 6P1 Tube Amplifier


When you use your mobile phone or computer to listen to music, you will find that the sound is small, the details are small, and the dynamic is thin, their sound quality aren’t full and pleasant like as CD player, decoder. This is because the output value of mobile phone and computer is 0.2-0.5V audio voltage only, while the existing power amplifier is generally designed with an input voltage of 0.75-1.2V. This intermediate voltage difference requires a 2x amplification boost value. Now the 1:2 signal boosting transformer solves this disadvantage.

 
1:2 signal boosting transformer, balance transformer, and inverter transformer, that is a passive boosting transformer developed to compensate for low signal output of computers and mobile audio sources in the existing market. Make the ordinary sound source close to the effect of CD player signal one. And, if CD player connected the signal boosting transformer to power amplifier, its sound will be even more powerful. After the audio signal pass the boosting transformer and amplify, it will output a stable impedance, it will lead to its signal transmission is fidelity, and its sound field positioning is better!

IWISTAO Long 4 inch Supper Tweeter Copper Horn Brass Horns Neodymium Copper Film

 IWISTAO Long 4 inch Supper Tweeter 1 Pair Copper Horn Brass horns Neodymium Copper Film 6Ω 30W 625HZ-40kHz


This super tweeter is made of brass integrated stretching for musical instruments. The curve of horn is a natural and smooth parabola with a horn design and good sound field positioning. The driver unit uses a 70mm diameter neodymium copper film one with a copper short-circuit ring, a high-permeability liquid, and an ultra-lightweight 40mm diaphragm made of beryllium copper to ensure that vibration quality is lighter and more air can be pushed at the same time. Makes the music spiritual and the details more real.


The drive is a powerful magnetic circuit composed of 8 rare earth neodymium magnets. There is a 0.15mm copper short-circuit ring at the T iron position, which can obviously eliminate the influence of the voice coil inductive reactance and suppress the increase of the voice coil inductive reactance with frequency. Improve high-frequency radiation and reduce distortion.



The voice coil is filled with a cooled and highly permeable imported magnetic fluid with damping and positioning effects. Magneto-fluid has a great influence on the audio curve. It not only cools the voice coil, but also has sealing performance. A good magneto-fluid plays a decisive role in smooth sound at high frequencies. The ring reciprocates in the magneto-fluid, and the magneto-fluid plays the role of automatic centering, which greatly changes the internal resistance of the horn, especially the air sensation of the sound, and the burr sensation of the speaker without the magneto-fluid is obvious in comparison.





This version is that Crystal binding post is fixed if you don't need connect it to a professional crossover. You can use this one connect with your full range or bass speaker directly in parallel.
