product description

From the 1960s to the early 1990s, the American audiophile manufacturer Audio Research Corporation (ARC) was known to everyone in the audiophile industry. At that time, the high-level enthusiasts who played Hi-Fi to the highest level often used ARC products.

Senior enthusiasts must remember some of ARC's popular boutiques. In terms of vacuum tube preamps, the SP-3A, SP-6B, SP-8, SP-10 Mark II and SP-11 Mark II are nostalgic. In the latter stage, there are D-52, D-70 Mark II, D-110B, D-350B and M-300 Mark II and so on. These pre- and post-stages, from the 1960s to the early 1990s, were all leading and famous fever boutiques.

Therefore, we have launched a fully balanced valve preamp with reference to the ARC circuit, which is affordable and has good sound performance. This is our design philosophy for a long time.

In terms of listening sense: its high frequency is flat and smooth without being harsh, the low frequency is low but not swollen, and the mid-frequency is slightly thin, but it is just right with the extension of the upper and lower frequencies. Although the analytical power and stage effect are not at the highest level, they are more natural than exaggerated.

Features and details of this product:

1. Customized grade 50VA full copper tape shielded R-type transformer,

2. With volume remote control and signal source switching function, two groups of balanced inputs, two groups of conventional RCA single-ended inputs, one group of balanced outputs, and one group of conventional RCA single-ended outputs.

3. High-voltage power supply: using capacitor array, lower internal resistance of power supply, stronger instantaneous dynamic, and using MOS power supply adjustment tube at the same time, it has a gallbladder smell and will not produce annoying noise of gallbladder rectification and voltage regulation.

4. The left and right channel DC filaments are independently regulated for power supply, which is pure and does not interfere with each other.

5. Fever-grade capacitive-resistance components, a new benchmark for valve pre-stages.

6. Standard all-aluminum chassis, high-end sandblasting design, beautiful atmosphere.

Detailed parameters

Works voltage: AC115V or AC230V for choose

 

Using Tubes: 2pcs Beijing 6N11 and 2pcs PSVANE ECC82

 

buyer also can update with other better tubes, 6N11=6922=6DJ8 ECC82=12AU7

 

Input port: 2 groups balance XLRand 2 groups Single ended RCA

 

Ouput port: 1 groups balance XLR and 1 groups Single ended RCA

 

note: when input Single ended audio. only output Single ended. No XLR output.

 

6N11 is used as cathode output in the output stage, ECC82 common cathode is used for voltage amplification in the first stage, and constant current diode is used as cathode constant current in the first stage. The output of the machine can be balanced and single ended, and the input also can be balanced and single ended.
