Power Class and Output Comparison
Output Power
Edge: Oilily A88 KT88 Tube Amp
The Oilily A88MK delivers 45 watts per channel in its Class AB design, while the A300B MK provides 8 watts per channel in pure Class A single-ended operation. This significant difference in wattage means the A88MK can drive more demanding speakers or fill larger rooms with higher volume. The A300B MK trades raw power for tonal purity, a common trait in Class A amplifiers. You should choose the A88MK if you need higher output levels, but the A300B MK is designed for listeners who prioritize the specific warm character of single-ended Class A over sheer volume capability.
Amplifier Class
Edge: Oilily A300B MK 300B Tube Stereo Amp
The A88MK operates in Class AB mode, offering a balance between efficiency and sound quality. It allows you to switch between Triode Mode for soft, pure vocals and Ultra-Linear Mode for dynamic, large-scale sound. The A300B MK runs in pure Class A single-ended mode, which is known for its classic 300B topology and tonal purity. Class A amplifiers are less efficient and run hotter but are favored for their specific sonic signature. If you want versatility in sound character, the A88MK offers dual modes. If you prefer the traditional, consistent warmth of single-ended Class A, the A300B MK is the better choice.
Tube Configuration
Edge: Oilily A88 KT88 Tube Amp
The A88MK uses four output tubes, specifically KT88 or EL34, driven by 6SL7 and 6SN7 preamp tubes. This configuration supports its higher power output and allows for tube rolling between KT88 and EL34 types. The A300B MK uses a pair of 300B output tubes, driven by 6N11 and 6N6 in the voltage stage, with a 5AR4 rectifier. The 300B topology is a classic design that emphasizes midrange detail and tonal purity over high power. The A88MK offers more flexibility in output tube selection, while the A300B MK sticks to the traditional 300B single-ended setup.
Connectivity Options
Edge: Oilily A300B MK 300B Tube Stereo Amp
