California hotel from IWISTAO HIFI M6.5 labyrinth speaker + 300B Tube Amplifier


The song California hotel form IWISTAO M6.5 labyrinth full range speaker plus 300B tube amplifier.

 

California hotel from IWISTAO HIFI M6.5 labyrinth speaker + 300B Tube Amplifier from IWISTAO HIFI MINIMART2 on Vimeo.


IWISTAO M6.5 labyrinth speaker is made of solid cabinet, and the speaker unit adopt mark 6.5 inch one with metal cone.



300B tube amplifier adopt 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 , 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.

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!
