The Perfect Upgraded 845 tubes : COSSOR 845

1.pure female and male voice stretch from medium frequency to low frequency, replenishing double bass and the drum set. The sound, full of thickness, power and dynamism, did never perform loosely even when rebroadcasting mass drum record......

2.Some loudspeakers with a power up to 90 dB turned out to be consuming. In this sense, High-voltage triodes are in request to successfully achieve the balance. COSSOR 845 can be one of the good choices.

3.Domestically-produced high-voltage triodes, the best partner of loudspeakers

4.Return of Time-honored UK COSSOR
COSSOR old players should be very familiar with COSSOR where vacuum tubes under GEC, OSRAM or other UK famous brands have been produced under commission, a proof of COSSOR’s good craftsmanship. And 52 KU can be the hottest under the category of U52 rectifiers and has been treasured by many antique tube users. Recently returned COSSOR has collaborated with PSVANE and rolled out a new series of vacuum tubes, among which the vanguard was COSSOR 845.

5.Large glass shield, specific coating, greater sound effect
Take COSSOR 845 from the box, you will find that the glass shield is relatively bigger than the 845, which can, as told the the rule the thumb, rise up sound effect. The black material coated in the internal layer also speed up the heat conduction, enabling a greater sound effect. Users can only notice the bright filament on the top of the tube, yet lost in stark darkness when they took a close look along “sweet spots”, which enables them stay outside the music.
Moreover, as revealed, the manufacturer has taken full consideration the damping coefficient, welding position, material and capacities to continuously upgrade COSSOR, in the hope of effecting its greatest performance in both dynamic and static operation.

Conclusion
Should COSSOR 845 be tested by stricter standard, it is expected to create a grander sound stage and greater stretching to sweet spots in low frequency, more bright in high frequency. It is supposed that only high-end tubes even the top ones are able to produce the features.But COSSOR 845, a high-voltage triode and a cheap entry level has displayed a far greater sound unmatched by attached tubes so that triode users can appreciate the same greatness as they did with 845 tubes.
