MAKING THE BEST BETTER

How do you take an admired and successful integrated amplifier, one that’s won respect and plaudits around the world, and make it even better? Well, if you’re a Cambridge Audio engineer, you examine every aspect of the performance - and then you do everything you can to make it ‘more’. More refined, more precise, more engrossing… more musical.

UNCOMPROMISED AND UNCOMPROMISING

All the research, all the development, all the time and effort that’s been expended on the CXA81 has been for one reason alone: to make this the most accomplished and absorbing integrated amplifier ever offered in its class. Every component selected, and every engineering decision taken, is based entirely on the desire to progress. The CXA81 has been designed and specified without compromise, in order to deliver the complete musical picture.

THE WHOLE STORY

The CXA81 is designed to bring your music to life, no matter how it’s stored. So it features an entirely new digital board, including the cutting-edge ESS Sabre ES9016 digital-to-analogue convertor. Which means digital audio files up to a heady 32bit/384kHz, or DSD256, are brought dramatically to life, with every detail and nuance delivered intact and in full. The CXA81 combines unparalleled accuracy with vivid musicality, without sacrificing convenience.

POWER AND CONTROL

Thanks to numerous improvements and upgrades - and thanks to an overspecified toroidal transformer - the CXA81 delivers a prodigious 80 watts of power per channel. This means the CXA81 has complete authority over even the most demanding speakers, it means big dynamic shifts in music are handled with total control, and it means the whole musical picture is available no matter if you’re playing at discreet background levels or at party-time volumes.

ABSOLUTE FLEXIBILITY

The CXA81 covers all connectivity bases, giving you complete freedom of choice. As well as digital optical and digital coaxial inputs, it features unbalanced stereo RCA inputs alongside balanced XLR sockets - and wireless connectivity via Bluetooth’s cutting-edge aptX HD standard is on board too. So there’s no need to compromise on performance in the name of convenience.

UNMATCHED SONIC INTEGRITY

At the heart of the CXA81 beats a completely reimagined and redesigned power amplifier stage with optimised capacitor values. The resulting sound is pristine but not clinical, with unrivalled musical coherence no matter the source.

User questions & answers

Question:	The appears to be 2 large capacitors - what are their temp rating and capacitance rating? What brand
Answer:	I've reverse engineered the circuit. The tubes are implemented as cathode followers post fade and feed the power amp inputs. The cathode follower implementation is a little strange in 2 ways: 1- Triodes are paralled but one plate is disconnected (pin 1) 2- Both channels are connected to B+ via a shared 220K resistor (haven't bench tested yet but CROSSTALK?!?!). Subwoofer outputs are on a separate path and not routed through the tubes.
Question:	Can i use this to power my front speakers and sub in a 5.1 through my avr that has pre-outs
Answer:	Hi Ryan J, Yes, the speaker system with 4 to 8 ohms will work with this AV Receiver. https://www.sony.com/electronics/support/res/manuals/4726/55cd375e0f9e7103f2b6baa747ed9072/47269061M.pdf (page 15 - Setting/Connecting Speakers) Regards, David
Question:	I read new stock due Oct will be sub controllable, the volume knob will control a subwoofer... has new stock arrived
Answer:	HI, Chris! Unfortunately, no. The Bluetooth feature of the receiver doesn't support connection of Bluetooth speakers. Regards, Erin
Question:	Are the tubes powering this amp, not just for show and is the sound warm when played
Answer:	Hi Allen W., The HDMI ports are actual HDMI inputs. You may refer to this link for more product information: https://docs.sony.com/release//SPECS/STRDH590_mksp.pdf ~Ralph

User questions & answers

Question:	Can this amplifier connect with 2 Denon home 150 wireless speakers (as surround speakers
Answer:	Nope. There's no logic to read or play the files from the flash drive directly. A computer or tablet or phone is needed to read and play the files, either digitally through the usb port, or analog through the Micca's RCA plug inputs. To the computer, the Micca looks like a sound card. Hope this helps. For what it is, though, the Micca is very high sound and build quality for the price.
Question:	Can it connect to pc
Answer:	Yes. It will work with input of 110-240 Volts.
Question:	How does this pma-150 heat radiation work? i had a little concern about overheating
Answer:	Hi, you can insert bare wire into the leads and then snug down the fastener on top of the wire. Or use banana clips. Both methods work

User questions & answers

Question:	I was wondering if these will drive a pair of pioneer sp-fs52 andrew jones designed floor standing loudspeakers at reasonable volume (small bedroom
Answer:	You can use either a pair of RCA or balanced XLR cables to connect the CXA81 to the CXN-V2. For optimum results, XRT cables are preferred.
Question:	Will this help enrich sound if the source is tidal on mac mini, and the speakers are already "powered" edifier s3000 pro
Answer:	I have not had any issues with volume control. I do make sure that my iphone volume is turned all the way up and use the remote on the unit to adjust.
Question:	Is the subwoofer out line-level or speaker-level
Answer:	Hello, Thank you for your question. All items sold on Cambridge Audio USA's Amazon platform (i.e. amazon.com) are 110V-compatible. The CXA81 is not a switch-voltage unit, and a CXA81 purchased from Amazon USA will be 110V. Best regards, Cambridge Audio USA
Question:	What is the cut off frequency for the low pass filter
Answer:	Highly accurate. Clear, concise sound. Nothing forced or pushed. Very easy to listen to for extended periods. Also very difficult to explain. Notice that this amp has no tone controls. I was dismayed by the lack of this feature at first but after listening, I could tell tone control was not needed. I very much like this amp. DAC and Bluetooth are also exceptional.
