A New Reference in High-End Amplification
The gaissei ultima2800MK3 MAX was created for serious audiophiles who demand the scale, control, and authority of the world’s finest amplification systems — without sacrificing musical soul.
It is not merely designed to play loudly.
It is designed to reproduce music with the effortless realism, emotional depth, and limitless dynamic authority of a true reference-class amplifier.
The silver-grey finish combined with contrasting black heatsinks gives the amplifier a bold three-dimensional visual presence that resembles modern industrial art more than traditional audio equipment.
For discerning owners seeking exclusivity, SP-AUDIO also offers optional custom finishes including black and red private-edition versions.
Intelligent Mechanical Grounding
The amplifier is equipped with SP-AUDIO’s exclusive air-suspension isolation footers designed to channel unwanted vibration away from the chassis structure.
This significantly lowers mechanical coloration and enhances clarity, imaging precision, and low-level detail retrieval.
For maximum performance, SP-AUDIO recommends installation on rigid flooring and high-mass equipment racks.
Sound Signature
The sonic character of the ultima2800MK3 MAX embodies SP-AUDIO’s core philosophy:
Naturalness. Musicality. Texture. Dynamics. Emotion.
Its presentation combines:
* Deep, authoritative, highly controlled bass
* Rich and magnetic midrange density
* Exceptionally refined treble extension
* Massive soundstage scale
* Explosive macro-dynamics
* Delicate micro-detail retrieval
Unlike many ultra-high-power amplifiers that prioritize brute force over musicality, the ultima2800MK3 MAX preserves warmth, liquidity, and emotional engagement while maintaining absolute control over the loudspeaker.
The overall presentation is effortless, transparent, fast, and highly immersive.

Massive Power Supply Architecture
Each monoblock is built around an enormous dual-transformer power supply design using:
* 2 × 2500VA ultra-high-current toroidal transformers
* Total transformer capacity: 5000VA
* 12 × custom SP-AUDIO 22,000µF capacitors
* Total capacitance: 264,000µF
Every transformer is individually housed inside its own metal shielding enclosure to minimize magnetic leakage and electrical interference.
