Spatial Europe AMP No2

Spatial Europe AMP No2 – single-ended EL34 tube amplifier with bespoke output transformers

The EL34 at its most direct

The Spatial Europe AMP No2 is a single-ended stereo tube amplifier, built exclusively by British valve specialist Audion for Spatial Europe. Two EL34 output tubes operate in class A, delivering 2 x 12 watts at 8 ohms — more than sufficient for the high-efficiency Spatial Europe loudspeaker models. Audion founder Graeme Holland personally matches the output transformers to the impedance and Qts of the chosen loudspeaker model, consequently optimising the electrical and mechanical relationship between amplifier and speaker from the outset. The AMP No2 is available at Novus Audio in Kampen.

Single-ended topology without negative feedback

The AMP No2 operates without negative feedback, thereby preserving the directness and expressiveness of the musical signal throughout the amplification chain. Class A operation maintains a constant current through the output tubes at all times, contributing to a consistently even, low-noise presentation. The EL34 is widely regarded as one of the finest output tubes for midrange purity and tonal warmth — qualities that single-ended operation brings out more fully than any push-pull topology. Furthermore, the wide frequency response of 14 Hz to 40 kHz ensures that neither bass weight nor high-frequency air is sacrificed.

Bespoke output transformers as standard

Graeme Holland matches each AMP No2's output transformers to the specific Spatial Europe model it will drive — a service included at no extra charge. This means the pairing between amplifier and loudspeaker is engineered rather than left to chance, above all in the critical areas of impedance matching and mechanical resonance control. The AMP No2 is recommended for the Spatial Europe Zero, No1, No2 TSE, and No3 TSE. For the larger models No4, No5, and No6, the AMP No3 with 300B output tubes is the recommended choice.

Tube rolling as a tool for personalisation

The AMP No2 is supplied without tubes, making tube rolling an integral part of the ownership experience. Different EL34 variants — from NOS Mullard and Telefunken to current-production Electro Harmonix or JJ — each bring a distinct character to the amplifier's presentation. Moreover, the choice of driver tubes offers a further layer of refinement. Our specialists at Novus Audio are happy to advise on the best tube complement for your system and musical preferences.

Frequently asked questions

What is the difference between the AMP No1 and the AMP No2?

The key distinction is the tube configuration — eight EL84s in parallel single-ended for 2 x 13 watts in the No1, versus two EL34s in classic single-ended for 2 x 12 watts in the No2. The EL84 sounds slightly livelier and more dynamic; the EL34 offers greater warmth and body in the midrange. Both amplifiers are recommended for overlapping Spatial Europe loudspeaker models.

Which Spatial Europe loudspeakers suit the AMP No2?

The AMP No2 is recommended for the Spatial Europe Zero, No1, No2 TSE, and No3 TSE. For the larger models No4, No5, and No6, the AMP No3 with 300B output tubes is the preferred choice. Contact Novus Audio for personalised advice on the best amplifier and loudspeaker combination for your system.

Are tubes included with the AMP No2?

The AMP No2 is supplied without tubes. Tube selection meaningfully influences the sonic character of the amplifier and can be tailored in consultation with Novus Audio. Our team is happy to advise on the most suitable options for your system and listening preferences.
