product description
Every time at a large-scale audiophile equipment exhibition, the well-known manufacturer Pass audiophile equipment makes the enthusiasts' blood boil! But the price stops most working audiophiles.
I am also a Pass fan. I have made many large-scale fever pure Class A power amplifiers for enthusiasts. I have a certain persistence in Pass power amplifiers. , well received by enthusiasts!
Pass is undoubtedly one of the world's high-end transistor audiophile amplifiers, and the old man Nelson Pass is undoubtedly one of the designers of the world's ultimate transistor amplifier circuits. The PASS series circuits he designed have always been the most popular among enthusiasts. One of the most imitated power amplifier lines, the reason is simply that the line is simple and the sound is good! However, the imitation of fans often cannot achieve excellent sound quality due to various factors such as the layout of the PCB board, the direction of the circuit, the matching accuracy of the power tube, and the matching of materials and tuning!
For this reason, we have launched this low-cost, high-performance single-ended pure class-A power amplifier. The materials used are feverish, the price is low, and the design and deployment are reasonable. At one-tenth of the price of the original machine, you can enjoy the same PASS A5 Single-ended pure class A mellow and beautiful sound quality!
This machine adopts the famous PASS ALEPH 5 single-ended class A power line, and the original machine is the HI-END power stage with more than 20,000 dollars. It adopts a large all-aluminum chassis similar to the PASS style, and the two-channel mirroring design makes the wiring more reasonable! The board adopts military 718 factory resistors, high-power imported non-inductive resistors. Electrolysis adopts nichicon (Nikon), electrodeless electrolysis, the sound is transparent and clear, the sound bottom is clean and neat, the level is good, the low frequency dives well, and the high frequency has penetrating power. The power amplifier tube adopts the new IRFP250 high-power field effect tube of the American IRF company. Each channel uses 6 pairs of 1% precision matching tubes, and the static current of each channel reaches 2A! Each channel is powered by an independent power board, which is composed of 12 Novartis 10000U/50V electrolytics and imported non-inductive resistors for CRC filtering, lower power supply ripple, and the total filter capacitor capacity of two channels reaches 240,000 UF! The transformer uses two 300W high-quality toroidal transformers A-grade silicon steel to be wound without fracture! (copper wire cattle), making the signal-to-noise ratio of the whole machine extremely high! The AC winding of each channel is independently powered, providing a strong power reserve for the rear stage. This machine is equipped with a balanced input interface and an unbalanced input interface, which is convenient for connecting balanced equipment. The whole machine is equipped with a high-power soft-start circuit and a horn protection circuit to ensure the safety of the transformer and the horn. The true dual-mono independent channel, each channel adopts independent rectification, independent protection device, independent transformer, each transformer uses a shield to isolate magnetic interference, the sound characteristics of this machine: high-frequency elegant and beautiful, intermediate frequency thick and sweet , the low frequency is elastic, and the driving force is strong, the control is super good! Long-term listening will not feel noisy, there is a tendency to attract you to want to listen to it, it is absolutely super durable! The signal-to-noise ratio is very high, and the humming sound cannot be heard even when the ear is close to the speaker. The temperature of this machine is high, please pay attention to ventilation and heat dissipation.
