TMR Safe Pack & Ship Guarantee

Our Safe Pack and Ship Guarantee means we guarantee its safe arrival. Items are carefully double-boxed or custom foam-molded. For larger pieces, we palletize to ensure secure, upright delivery. In rare cases of loss or damage, we fully protect your purchase.

Shipping Cost

Shipping within the Continental USA is $799.00—this includes securing to a pallet with adequate protection and shipping via FedEx Freight to a residential address anywhere in the Continental USA. This rate can be reduced by $60 if a commercial delivery address is available or if the item can be picked up at the nearest FedEx Freight depot. FedEx Freight charges a residential delivery fee otherwise, which is included in our flat rate charge.

We DO NOT offer international shipping.

Product Highlights

No factory remote. Unit is self-biasing.

Specifications: Output Power of 450 Watts per channel into 5 ohms in Tetrode mode and 220 Watts per channel in Triode mode. The VTL S-400 Reference Series II is a flagship stereo vacuum tube power amplifier engineered to deliver immense power with high-end musical delicacy. Built around a fully balanced differential circuit topology and a massive energy-storage power supply, it effortlessly drives demanding loudspeaker loads. Microprocessor-controlled automatic biasing and active fault sensing eliminate routine manual maintenance, while on-the-fly Tetrode to Triode switching allows tailored sonic presentation for any genre.

Reviewers consistently praise the S-400 Series II for combining the sweet, fluid textures and holographic imaging of fine tube designs with the speed, slam, and authoritative bass control typically reserved for high-power solid-state amplifiers. Critics highlight its ultra-quiet background and uncanny ability to resolve delicate micro-details within complex musical passages. The automated biasing system is widely celebrated as a triumph, making reference-level tube performance completely hassle-free for daily listening.

Integrating this powerhouse into your audio system secures an ultimate balance of visceral dynamic impact and refined acoustic transparency. It stands as the definitive upgrade for audiophiles seeking pure musical realism, limitless headroom, and uncompromising loudspeaker control that breathes vivid life into every recording.
