Trafomatic Audio Pandora
When opening Pandora’s box Greek mythology tells us to expect “Any source of great and unexpected troubles”. Now imagine you must open 2! Even more sources of trouble?
Not when those boxes of Pandora are delivered by Sasa Cokic. Each of these boxes contain one of the finest tube mono amplifiers on the market, presented to you under the name Pandora. Designed to bring you the ultimate musical experience and joy.
Beautifully hand crafted designed housing, technically based upon the Svetlana 811-10 power tubes these mono amps deliver you up to 40 Watts in pure Class A each.
Sonically the Pandora mono amplifiers present a grand palette of musical textures in the best Trafomatic fashion. Bass is tight and fast, the mid-range glorious, the high frequencies liquid and airy.
Features:
Imagings are superbly holographic and the soundstage vastly layered and wide. While sonics are stunning, they will never be in the way of the music’s embedded emotions. The Pandora mono’s are dynamic amplifiers with a firm grip on the beat to convincingly portray musical motion and faithfully capture how live music flows over time. They recover plenty of detail, provide very good articulation of vocals, produce a large sense of space and build their virtual stage on rock-solid imaging.
Pure and elegant in design, circuit minimalism with very high quality parts preserves the primal qualities of reproduced sound and opens up new dimensions for the playback experience.
The Pandora monoblocks run two drivers tubes 6N30P called also “super tube” and two direct heated triode made by Svetlana 811-10. Each amp houses an epoxy resin-potted 6kg double C-core output transformer, 10Kg main power double C- core transformer , one high inductivity filter choke and an interstage transformer for driving SV811-10 tubes all made by Trafomatic Audio
High-level line input transformer LL1592 provide phase splitting with high degree of simetry.
All tubes are with DC heating to improve signal / noise ratio .
Pandora used -3dB of NFB just in output stage ( cathode feedback )
Pandora doesn’t use capacitors in signal way .

Trafomatic Audio Pandora — Push-Pull DHT Monoblocks
The Pandora pairs rare direct-heated SV811-10 triodes with a transformer-centric topology to deliver a transparent, highly controlled tube presentation. Reviewers at Marja & Henk highlighted a very low noise floor and an authoritative transient grip that belies its 40W per channel rating. Key engineering choices — a 26-winding interstage transformer, double C-core output transformers and just 3dB of local feedback — support tight dynamics, coherent imaging and minimal tube-induced coloration. The monoblocks are boutique-built (resin-impregnated plywood, DuPont rubber finish, back-lit Kyoritsu VU meters, WBT binding posts) and suit efficient or highly resolving speakers. For listeners seeking hand-crafted transformer engineering and tonal purity rather than maximum wattage, the Pandora is a compelling, high-end choice.
Pros
- Exceptionally transparent, low-noise presentation with minimal tube coloration, allowing fine detail to come through.
- Strong dynamics and control for a 40W DHT design — retains authority and headroom at realistic listening levels.
- Outstanding transformer and mechanical engineering (26-winding interstage transformer, double C-core outputs, DuPont finish) that supports sonic transparency and build solidity.
- Thoughtful connectivity and ergonomics — true balanced XLR/RCA inputs, ground lift, WBT posts and useful VU meters for a refined user experience.

Cons
- Large, heavy monoblocks (about 32 kg each) require significant space and careful handling during installation.
- Positioned as a boutique, premium product — review sample listed at €24,000/pr, so cost may put it beyond many buyers despite its engineering merits.

Dynamics
91/100
Push-pull DHT Class A monoblocks delivering 40 Wpc showed notable headroom and control in listening. Reviewers described the sound as "clean, dynamic and powerful" and noted the amps remained dead-silent up to high levels, with the design's low feedback (3 dB) and transformer engineering cancelling 2nd-order harmonics and contributing to authoritative transient grip. Monoblock construction, large transformers and the ability to expose detail on very efficient speakers were cited as evidence of strong current delivery and speaker control.
Soundstage Imaging
89/100
The Pandora produced realistic instrument sizing and convincing scale at realistic listening levels (reviewers mentioned 87–90 dB in the sweet spot), with an expansive, stable presentation that handled dynamic material well. Imaging remained coherent even when driving demanding program material, giving sense of space and depth without apparent smearing.

Build Quality
94/100
Robust boutique construction: heavy 32 kg per mono chassis, resin-impregnated plywood panels, DuPont rubber/coating that damps micro-vibrations, large double C-core output transformers and a complex interstage transformer with 26 windings. Premium touches (WBT binding posts, back-lit Kyoritsu VU meters) plus the monoblock layout and evident attention to thermal/mechanical detail justify a very high build score.
Value for Money
86/100
Review lists the loaner pair at €24,000/pr and the spec'd output is 40 W per channel (push-pull DHT Class A monoblocks). The reviewer offers no explicit value judgment, so a neutral baseline is applied: the Pandora is clearly a premium, boutique product with exceptional build and transformer engineering, and is priced in line with high-end tube monoblocks; compared with solid-state alternatives at similar money (which deliver far more raw watts) the Pandora is a boutique, lower-power offering best justified to buyers prioritizing DHT tube character and hand-built engineering rather than maximum wattage.
