Purchasing, listening and delivery
Ordering and system matching
Ask about the selected version and matching with your amplifier, sources and room. Supply arrangements will be confirmed in the quotation. An enquiry does not confirm a sale.
Listening sessions and demonstrations
You can request a listening session by appointment at our Barcelona office (Carrer de Modolell, 57). When we arrange the appointment we confirm which equipment is available to hear, along with the date and time.
Home demonstrations are not offered for this product.
Delivery and setup
Delivery, its cost and the estimated timing are confirmed in writing in your quotation, for your delivery address and before you accept it.
Installation and setup can be requested as an additional service. We assess feasibility and quote it separately.
Planning your system
The SLI-100 combines a preamp and push-pull ultralinear output stage with four KT150 valves. Cary rates it at 100 W per channel and lists four pairs of RCA line inputs; the nominal rating is distinct from a measurement with a defined load and distortion threshold. For the 4 or 8 Ω output setting, provide your speaker model, listening distance and usual level. The manual documents a 6.35 mm headphone socket and full-range RCA output for an active subwoofer. Ask about availability and listening arrangements for your system.
Editorial Reference
Model context
Position within the Cary range
Push-pull ultralinear integrated amplifier with four KT150 output valves, rated by Cary at 100 W per channel.
Why choose this model?
Compare its Cary-rated 100 W per channel ultralinear output and four RCA input pairs with the modes and three RCA pairs of the SLI-80HS. Provide your speaker model and load, listening distance and usual level to assess the combination.
For which system does it make sense?
- Systems requiring four pairs of RCA line inputs; speaker choice requires checking the load, listening distance and usual level.
- Four line inputs and a headphone output for versatile use in the living room.
- Integration with active subwoofer.
Differences compared to similar models
Greater ultralinear power than the SLI-80HS and fixed KT150 tubes; does not feature triode mode. The top entry point in the SLI family in terms of power.
Architecture and Design Decisions
Push-pull ultralinear configuration with four KT150 output tubes, two 6922 input tubes, and two 6SN7 driver tubes. Four RCA inputs, subwoofer output, and a 6.35 mm headphone jack; speaker terminals for 4 and 8 Ω.
Compatibility and Use
Compatible with RC-300. Pair with VT-500 or SLP-98P if vinyl is the primary source.
Official specification limits
Cary Audio does not publish triode mode for the SLI-100. Headphone impedance is not stated on the web specification sheet.
