The KEF Q300 is an 8-ohm, 87dB-sensitivity bookshelf speaker that KEF itself rates for 15-120 watts — a fairly bright-leaning speaker that pairs well with a warmer, laid-back amp rather than another bright component. These 9 are real, currently-sold integrated amplifiers pulled from live retailer listings, from a $499 NAD entry point to a $1,199 Cambridge Audio flagship.

The picks, in detail
NAD C316BEE V2
Frequently recommended in Q300 owner threads as a warmer counterweight to the speaker’s brighter character, with enough clean power on tap to drive the Q300’s 87dB sensitivity comfortably.
- 40W per channel (8 ohm)
- Built-in MM phono stage
- Compact chassis
- Well-matched warm tonal balance for a bright speaker
- Includes phono input
- No digital inputs or DAC on this entry model
Yamaha A-S501
Yamaha’s laid-back house sound is often cited as a good contrast to the Q300’s brightness, with 85W per channel and a built-in MM phono stage for a fully analog setup.
- 85W per channel
- Built-in MM phono stage
- Continuously variable loudness control
- Laid-back tonal balance suits a bright speaker
- Strong power reserve for the Q300’s 8-ohm load
- Styling and feature set skew toward a more traditional hi-fi look
Denon PMA-600NE
A modern Denon integrated with 70W per channel, Bluetooth and a built-in phono stage — a versatile all-rounder for a Q300-based system that also wants wireless streaming.
- 70W per channel
- Built-in Bluetooth and DAC
- Built-in phono preamp
- Wireless streaming built in
- Good all-around value
- Less headroom than the higher-power options here for large rooms
Marantz PM6007
Marantz’s house tuning leans warm and musical, which several owner threads point to as a good complement to the Q300’s forward top end, with 45W per channel and a built-in phono input.
- 45W per channel
- Reference-class AK4490 DAC
- Built-in MM phono input
- Warm Marantz house sound
- Strong DAC for the price
- Lower rated power than the NAD or Yamaha options
Rega io
Rega’s smallest integrated amplifier — a simple, musical design with a built-in phono stage, aimed at listeners who want a straightforward two-input setup rather than a feature-heavy amp.
- 30W per channel
- Built-in MM phono stage
- Two-input simplicity
- Rega’s musical, rhythmic house sound
- Compact footprint
- Least powerful amp on this list, closer to the Q300’s minimum recommended wattage
Rega Brio Mk7
Rega’s flagship compact integrated, with meaningfully more power and refinement than the io for listeners who want the same house sound with more headroom for the Q300.
- 50W per channel
- Built-in MM phono stage
- Class AB design
- More headroom than the entry-level io
- Same musical Rega tuning
- Among the pricier options on this list
Audiolab 6000A MkII
Audiolab’s well-reviewed 6000A gets a MkII refresh with an upgraded DAC chip and power supply, delivering serious current into an 8-ohm load — good headroom for the Q300 with digital inputs built in.
- Improved ES9038Q2M DAC
- Upgraded 200VA toroidal transformer
- Multiple digital and analog inputs
- Strong current delivery for a full-bodied bass response
- Comprehensive digital connectivity
- Newer MkII revision has a shorter used-market track record than the original
Cambridge Audio CXA81 MkII
Cambridge Audio’s mid-tier flagship with 80W per channel of Class A/B power, a resolving ESS Sabre DAC and Bluetooth aptX HD — the most powerful, feature-rich option here for a larger room.
- 80W per channel, Class A/B
- ESS Sabre DAC
- Bluetooth aptX HD
- Most powerful amp on this list
- Full digital hub with high-res Bluetooth
- Priciest option here
Arcam A5+
Arcam’s current entry-level integrated with Bluetooth 5.4 and Auracast support, giving 50W per channel in a compact package for listeners who want a more contemporary feature set.
- 50W per channel
- Bluetooth 5.4 with Auracast
- Multiple analog and digital inputs
- Modern wireless feature set
- Solid power for the Q300’s sensitivity
- Newer to market with fewer long-term reviews than Rega or NAD
Buying tips
- KEF rates the Q300 for 15-120 watts into 8 ohms — every amp on this list falls inside or near that window, so power isn’t the deciding factor; tonal balance is.
- The Q300 is a bright-leaning speaker, so several owner threads specifically recommend a warmer amp (NAD, Yamaha, Marantz) over a similarly bright one.
- If you play vinyl, prioritize an amp with a built-in MM phono stage (NAD, Yamaha, Denon, Marantz, Rega) to avoid buying a separate phono preamp.
- The Q300’s 87dB sensitivity is on the lower side, so avoid pairing it with a very low-power amp in a large room even if it falls within KEF’s rated range.
