Vincent SP-T700 Hybrid Mono Power Amp Black (each)

The Vincent SP-T700 is a mono power amp (monoblock) using hybrid technology: a tube input stage meets a transistor output stage that operates in Class A. Each SP-T700 amplifies exactly one channel – so for a stereo system you use two units. The price is per monoblock.

Why the SP-T700?

Because the mono principle gives each channel its own, completely separate unit – with its own power supply and no crosstalk from the neighbouring channel. This benefits spaciousness and speaker control. The tube input stage uses 100% selected variable-mu tubes from military stock (rated for 10,000 operating hours), while the transistor output stage delivers up to 10 watts at 8 ohms in pure Class A, with strong reserves above that of up to 150 watts at 8 ohms or 300 watts at 4 ohms. This lets the SP-T700 combine refined reproduction with the punch you need.

What you get

• Mono power amp (monoblock) – one unit per channel, price per unit
• Hybrid technology: tube input (selected military variable-mu tubes) plus transistor output stage
• Class-A operation up to 10 watts at 8 ohms, above that up to 150 W (8 Ω) / 300 W (4 Ω)
• RCA input (mono) for connection to the preamp
• A/B speaker terminals, bi-wiring capable
• Tube viewing window with dimmable lighting
• Power Control and switchable auto-standby

Who is the SP-T700 suited for?

For anyone who wants a genuine mono power amp solution – the ultimate in channel separation and speaker control. Ideal paired with a high-quality preamp like the Vincent SA-T7 MK. Honestly: you need two units for stereo, so double the budget and double the floor space – and being a Class-A unit, each monoblock generates noticeable heat and wants to stand freely. If you prefer something simpler and cheaper, the stereo power amp SP-332 serves you well.

Our verdict

The SP-T700 is Vincent's offer to anyone who wants to build a consistently mono system: separate amplification per channel, tube warmth at the input and Class-A finesse at low levels. Paired with a Vincent preamp, this creates a genuine reference chain. HiFi.Test praised the powerful hybrid circuit and the extremely solid construction in its review.

Frequently asked questions

Do I need two SP-T700s for stereo?
Yes. The SP-T700 is a mono power amp and amplifies exactly one channel. For a classic stereo system you need two units – one for left, one for right. The listed price applies per monoblock.

What does Class-A operation mean?
In Class-A mode, the transistors remain permanently under current, which eliminates switching distortion – considered especially clean-sounding. The SP-T700 delivers up to 10 watts at 8 ohms in pure Class A; reserves of up to 150 watts are available for higher levels.

Is the SP-T700 a tube power amp?
It's a hybrid power amp: the input stage works with selected variable-mu tubes, while transistors handle the power amplification. This combines tube character with the power and control of a transistor power amp.

Which preamp suits the SP-T700?
Classically, the Vincent tube preamp SA-T7 MK – as a matched reference chain from one house. Via the RCA input, though, the SP-T700 can be combined with any preamp that has a clean pre-out. This model does not have an XLR input.

Why buy the SP-T700 from HD Zürisee?
Because we advise you on the right combination of preamp, monoblocks and speakers before you commit. As a Vincent specialist dealer, we take care of setup and service and are personally there for you in Wädenswil on Lake Zürich even after your purchase.
