The Parasound NewClassic 275 v.2 is a high fidelity two channel power amplifier.
A new classic in every sense of the word, the 275 v.2 is the most compact member of Parasound's NewClassic line of high end home theatre and two channel audio products.
Each of this cool-running power amplifier’s two channels can deliver 90watts into 8 ohms, 150 watts into 4 ohms (also 150 watts into 2 ohms when set up correctly) and 200 watts when bridged to mono into 4 or 8 ohms. This exceptionally rugged amplifier is equally capable of driving high quality home theatre and stereo loudspeakers, or chains of in-wall and ceiling speakers. The heart of this flexibility lies in the amplifiers design and high level internal components, and the fact that the power amplifier has been designed with Parasound's proven class AB amplifier technology. The amplifier benefits hugely from fully discrete circuitry with toroid transformers and an efficient, low heat design.
The NewClassic 275 v.2 is a great performer for low impedance loads as the unit has a dedicated impedance selector switch for 2 Ω operation, meaning that it can drive the most demanding of loads if required. If you are working the unit in a higher power set up the unit can be set to drive more power into single loads as it also has a dedicated switch for bridged mono operation as well. The amplifier also has both speaker A & B outputs as well - meaning that you need not use two amplifiers to use in bridged mono mode necessarily (but be clear - see the manual outlining the 'bridged mono' set up!), making it a great slim-line and compact power house for high performance systems where rack space might be limited. If things get too harsh - the amp also benefits from both high temperature indicators and DC Servo with relay protection circuits.
This unit is a very adaptable performer, as it can also be used in a home theatre for instance (as alluded to before - not just in 'standard' stereo or distributed audio applications) as the 275 v.2 also has a 18dB/octave high pass filter, with switchable 20Hz or 40Hz. Why? Your speakers commonly have greater dynamic range and far less distortion when they don’t receive frequencies which are lower than they are capable of reproducing. Because the 20 Hz filter also has a steep 18 dB per octave slope, it is essentially a sub- sonic filter, and you probably won’t notice any loss of low bass unless you’re using very large speakers. This means that you can route all lower frequencies to a dedicated sub and really let your speakers get the best detail from the source material through the mid to higher frequency range in any application that will be geared around a 'sub/sat' system - 2.1 or 5.1 etc.
Like most Parasound amplifiers the 275 v.2 has great custom installation pedigree, with flexible power adaptability provided by automatic on/off by DC trigger with looping output and also automatic on/off by audio signal with adjustable sensitivity
The NewClassic 275 v.2 is a crystal clear example of why Parasound has a long history of dedication to superlative overall quality. The Model 275’s quality of sound, quality of performance and quality of construction will bring you listening pleasure for many years to come, as Parasound quality is also matched with their legendary reliability.
The Parasound 'NewClassic' 275 v.2 is available in black only.

Parasound’s Halo A 23 Amplifier is the ultimate combination of cutting edge technology, superb craftsmanship, and stunning industrial design. With high current Class A/AB amplification, smooth sounding MOSFET drivers, and balanced XLR inputs, this mighty amp will make any speaker sound better than ever before. The A 23 two channel amplifier boasts 125 watts of THX Ultra 2 certified power per channel, and it looks as amazing as it sounds. Whether it’s movies or music, the A 23 will knock your socks off!
As the A23 is based on a John Curl design (akin to the A21, A31 and A51) it boasts the exemplary qualities you'd expect - but at a lower price point than the more prominent A21. The A23 like it's two channel stable-mates can be used to stunning effect with the Parasound range of pre-amplifiers such as the JC3+, P5 or the larger and flexible P7 - perhaps within a multi-channel application. It can of course be used effectively as a 'mono-block' in bridged mono mode as well meaning that you can get a very dexterous 400 watts into an 8ohm load for those of you requiring huge power into larger more challenging loads or larger spaces.
As you would expect the build quality and components used in the A23 are like all of Parasound's range - very high quality. The A23 features both balanced and unbalanced inputs (RCA's are gold plated) with a designated ground lift switch, and these high quality inputs are matched with heavy-duty 24k gold-plated 5-way speaker terminals on the output stage. For those also wanting to tweak their systems to THX certified installations the A23 features adjustable gain pots for up to THX Reference level.
Despite it's impeccable 'HiFi' credentials (as it has like a host of Parasound's amps - been extremely well reviewed) - the A23 also can be mounted via a set of optional rack ears and has a choice of power activation (front panel, auto sensing and 12v) to ensure that for those wanting the best sound in a custom installation, the A23 becomes a mandatory option.
The Parasound Halo A23 is available in black and silver finishes - please specify on order.
