The A23+ has improved components and can deliver 28% more power than its predecessor. The Parasound 2100 preamplifier and 2250 power amplifier offer sound quality across the board so good I would have thought you'd have to pay at least $3,000 to get them. The Auralic Aries G1 streamer (streaming Qobuz and Tidal) and PS Audio PerfectWave Transport were the primary signal sources during the review with the digital-to-analog signal conversion performed by the PS Audio PerfectWave DAC II. While the A23+ may not be the best in every respect, it can deliver well above average in all aspects of the sonic performance. The built-in power supply is pretty good, too, with a shielded power transformer, a high-quality bridge diode and filter capacitors. Then there’s the way it handled the driving bass on Girls Go Wild, once again compartmentalising the various instruments while at the same time not separating them out from the mix, but integrating them into the whole. These results make the Parasound Zphono XRM completely compatible with any MM or MC cartridge we’ve ever heard of. The RIAA-corrected frequency response of the Parasound Zphono XRM, as measured by Newport Test Labs, is shown in Graph 1 below. Parasound’s amplifiers are well known and established products, which is of no surprise considering the legendary amplifier designer, John Curl, has been involved in the company’s amplifier product development since its early years. On this graph, the black trace is the response without the infrasonic filter and the red trace is the response with the infrasonic filter deployed. The Parasound Zamp V3 is not the kind of product you might expect to see on a Head-Fi review. By What Hi-Fi? Newport Test Labs measured the signal-to-noise ratios of the Zphono XRM using that input voltage which resulted in a 2V output on the highest gain settings for both MM and MC inputs and, as you can see, the Zphono delivered outstanding S/N results of 95dB A-weighted for its MM input and 81dB A-weighted for its MC input. Overall, the Parasound NewClassic 200 integrated amplifier is a good looking product. The Parasound Zphono XRM provides ample gain for both moving-magnet and moving-coil cartridges, as you can see for yourself from the tabulated results. What Hi-Fi? The A23+ might look lean and rather petite in the power-amplifier world, but it showed no sign of struggle at all in navigating the Ultima Studio through the soft and loud musical passages in a dynamic track such as Hopper Dance by Empire Brass Quintet from their Passage: 138 B.C. ), As luck would have it, we also had problems choosing which gain setting we should use – 50dB or 60dB – because the Ortofon Cadenza Blue’s output (which the specifications say is 0.5mV at 1kHz at a recorded velocity of 5 cm/sec) is right on the cusp of choices… at least it is according to Parasound, which recommends that you use the 60dB setting ‘for low output moving coil cartridges whose output is less than 0.5mV’ and the 50dB setting ‘for high output moving coil cartridges.’. The A 21 amplifier is loaded with usable features above and beyond most other amplifiers. Parasound’s Halo A 31 might get overlooked because it’s a three-channel amplifier designed primarily for use in multichannel home-theater systems -- or because, at $3295, it costs more than a budget multichannel amplifier, if less than what many audiophiles would pay for a two-channel amp. A 2mV input at the MC input, using the 60dB gain setting, results in 1.5V at the unbalanced output (3V at the balanced output). Our Verdict. Though I had inquired of Parasound's Director of Sales, Phil Jackson, back in late 2018 as to my doing a review whenever the reimagined JC 1 might make its way back into the Parasound roster, when the January 16, 2020 Press Release landed in my inbox, I immediately requested a listen! This puts the audio band frequency response at 20Hz to 20kHz ±0.45dB, which is excellent. Even though Parasound is a "high-end" audio company, this seems to be their attempt at mass market product as the retail price from Amazon is … It replaces an old but tough sc-305 JBL center. In that time, Parasound has established itself as a quality manufacturer. They can be switched out of the signal path when not needed, giving a slightly clearer sound. The gain of the moving-coil input can be switched between 50 and 60dB, and that of the moving-magnet input between 40 and 50dB, both via miniature toggle switches. Parasound's Halo JC5 conforms to some of these stereotypes, but there's more to it than just slam There's nothing terribly unusual about a big, hefty US-made power amp: after all, it's almost an archetype of what we think the US high-end is all about. Instead of silk-screened lettering, the ‘Parasound’ brand on the new faceplate has a 3D texture with gold lettering.
