ITOK Media Limited’s innovative Hi-Fi brand “Trends Audio” launched its new innovative Hi-Fi product – Trends PA-10 GE Tube Headphone/Pre Amplifier. It is a hybrid design utilizing a single 12AU7 input vacuum tube and two MOSFETS as the output drivers. Integrating new electronics technologies with traditional wisdom, Trends PA-10 GE Tube Headphone/Pre Amplifier brings audiophiles and music lovers the outstanding Hi-Fi gears in affordable price and compact hybrid Swiss army knife type of pre amplifier.
“After our successful release of Trends PA-10 Tube Headphone/Pre Amplifier in 6DJ8/6922 tube type, we got very good response and sales in Headphone and Hi-Fi field. Many users or dealers eager to have a 12AU7 tube type so that they need not adjust the jumper settings and let the audiophile enjoy the sound from different 12AU7 tube type” says David Ho, the marketing director of Trends Audio. ” We have already pre-set the jumpers and fine-tuned the DC bias voltage of each Trends PA-10 GE tube before shipping. However, changing different tubes to taste for different sound is the great fun for many audiophiles and also a great feature of Trends PA-10. The users can download our Technical Notes if they want to change the tubes. Trends PA-10 GE is one of the best choice to consider for audiophile or music lovers who like to listen to quality music while you work, or pair it with any power amplifier and you can play your music from PC/Mac/iPod through some good quality high efficiency speakers.”
Trends PA-10 supports two major tube series:
- 6DJ8, 6922, 6N11, 6H23n, ECC88, E88CC, etc., and
- 12AU7, 5963, 5814, ECC82, etc.
If the users change the tube within the same series, it needs to re-tune the DC bias voltages ONLY. If you change the tube from another series, it needs both to re-tune the DC bias voltages and re-set the jumpers. The audiophile and music lover is immediately evident that the Trends PA-10 GE is much warmer, more laid back and excellent female vocals and it would be another new revolution of Hi-Fi community.
