Contact showroomExplore vacuum-tube amplification built around the music. Audio Exchange can help you choose a VAC integrated amplifier, separates, or phono stage around your speakers, sources, and listening room.
Start with an integrated amplifier, combine a line stage and power amplifier, or give your vinyl system a dedicated phono stage. We’ll help compare the roles before choosing the components.
A complete amplification starting point
Combine source selection, volume control, and tube power amplification in one component. Sigma 170i includes VAC’s iQ automatic bias system and offers optional MM/MC phono and balanced-input configurations.
We’ll confirm the exact unit and fitted options. Phono inputs, balanced connections, Special Edition details, and finish should be checked individually.

Separates · Match the speaker and room
Explore VAC’s power-amplifier range, including Statement 455 iQ, Master 300 iQ, Signature 202 iQ, and Essence 90 iQ Monobloc. Start with your speakers and the listening levels you want.
Musicbloc operating modes and output connections vary by model. We’ll review stereo or mono configurations, the partnering preamplifier, speaker loads, and equipment space. Master 300 iQ shown.

Separates · Sources, control, and volume
Compare Statement Line, Master, Signature Mk IIa SE, Renaissance Mk V, and Essence line-stage options. Choose the source connections and control arrangement that suit the rest of your system.
A line stage needs a power amplifier or suitable active speakers. Phono capability is model- and configuration-dependent. Renaissance Mk V shown.

Vinyl · Match the cartridge
Explore Renaissance Phono and Statement Phono for a dedicated approach to vinyl playback. The cartridge, turntable, gain, loading, and amplifier inputs belong in the same conversation.
A phono stage amplifies and equalizes the cartridge signal; it does not replace speaker amplification or the system’s volume control. Renaissance Phono shown.

A considered match
Speaker demands, source levels, cartridge output, and the listening space guide the choice. We’ll also review the practical details of living with tube equipment, from placement and ventilation to future service.
Share speaker sensitivity, impedance information, room size, and listening distance. Amplifier selection goes beyond comparing nominal wattage.
For vinyl, tell us the cartridge model and output. We’ll check MM or MC requirements, gain, loading, and whether a fitted phono option or separate stage is appropriate.
On equipped amplifiers, VAC’s iQ system continuously manages output-tube bias and provides tube-status monitoring. It does not remove the need for appropriate placement, care, and tube replacement over time.
Allow suitable ventilation and safe clearance around hot tubes. Review rack load capacity, cable access, protective covers, and service needs for the chosen model.
Audio Exchange · Richmond
Send speaker and source models, your room dimensions, and what you want to improve. Include the cartridge if you listen to records.
Discuss an integrated amplifier or separates, connection needs, phono options, component placement, and how the system may grow.
Review current availability and a tailored quote. Contact us before a visit if you want to hear a particular VAC component so we can confirm what is available to demonstrate.
An integrated amplifier combines source selection, volume control, and power amplification. Separates use a line stage or preamplifier with a power amplifier, allowing those roles to be chosen independently. Speaker demands, connections, available space, and budget guide the decision.
No. Some offer optional phono configurations, and VAC also makes dedicated phono stages. We’ll confirm the exact model and fitted options, along with the gain and loading requirements of your cartridge.
No. On equipped models, iQ manages output-tube bias and helps monitor tube condition. Tubes remain service items, and correct ventilation, handling, and the model’s care instructions still matter.
Possibly. Tell us the speaker model, room size, listening distance, and preferred volume. We’ll review sensitivity, impedance, amplifier configuration, and output connections rather than assuming every tube amplifier suits every speaker.
Selected VAC Musicbloc amplifiers support different stereo, dual-mono, or mono operating configurations. The available modes and connection requirements depend on the exact model. We’ll review an appropriate expansion plan before specifying the equipment.
Yes. Call our Richmond team or use the form below with your equipment list and the VAC components that interest you. Contact us first about demonstrations so we can confirm the available equipment and arrange a useful visit.
Personal advice. A tailored quote.
Tell us about your speakers, sources, room, and what you want to hear from your system. If vinyl is part of the plan, include your turntable and cartridge models.
