A personal introduction from Sunil at Sunny's Audio Video.\u003c\/em\u003e\u003c\/p\u003e\u003cp\u003eThere are certain products that become part of our customers' lives, bringing countless hours of musical enjoyment and reminding us why we fell in love with high-end audio. For me, the CH Precision P1 Phono Preamplifier is one of those very special products.\u003c\/p\u003e\u003cp\u003eSince the P1's introduction on May 6, 2016, we have had the pleasure of selling several at Sunny's, and many of our customers continue to enjoy them immensely. But CH Precision's engineers never seem content to stand still.\u003c\/p\u003e\u003cp\u003eFollowing the introduction of the two-chassis P10 in May 2023, the team explored how its advances could benefit the 1 Series. On October 23, 2026, that journey reached another milestone with the announcement of the P1.5 Phono Preamplifier and L1.5 Line Preamplifier, joining the D1.5 and A1.5 in the evolving 1.5 Series.\u003c\/p\u003e\u003cp\u003eThe P1.5 brings advances developed for the flagship P10 into an integrated, single-chassis design, with careful attention to cartridge behavior, amplification, noise control, and equalization.\u003c\/p\u003e\u003cp\u003eImagine a familiar recording revealing a little more texture in a voice, a more natural piano decay, or a deeper sense of space around the musicians. Great engineering should bring us closer to the music, not simply impress us with specifications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWe are awaiting our demonstration component.

Proper setup, loading, gain matching, tonearm alignment, and the relationship between every component in the analog chain make an enormous difference.\u003c\/p\u003e\u003ch3\u003eGain and Loading Wizards\u003c\/h3\u003e\u003cp\u003eThe Gain Wizard helps identify an appropriate gain setting for your cartridge and input, supporting dynamic range while reducing the risk of noise and overload. Gain is adjustable in 3 dB increments.\u003c\/p\u003e\u003cp\u003eThe Loading Wizard displays the measured frequency response of the connected cartridge and tonearm combination at different loading values. It is an opportunity to evaluate electrical behavior rather than relying entirely on generalized recommendations.\u003c\/p\u003e\u003ch3\u003eDedicated Mono Configurations\u003c\/h3\u003e\u003cp\u003eThe P1.5 accommodates stereo cartridges playing mono records, dual-coil mono cartridges, and single-coil mono cartridges, without requiring changes to the normal connections between the phono stage and line preamplifier.\u003c\/p\u003e\u003ch2\u003eEngineering \u0026amp; Equalization\u003c\/h2\u003e\u003ch3\u003eThree-Stage Amplification Inspired by the P10\u003c\/h3\u003e\u003cp\u003eThe P1.5 employs three active gain stages with passive equalization between them and fully discrete Class-A amplification. Compared with the original P1, its design addresses input noise, available headroom, gain flexibility, and equalization accuracy.\u003c\/p\u003e\u003cp\u003eInput noise is reduced by approximately 6 dB on the current-sensing inputs and 4 dB on the voltage-sensing input compared with the P1. These are meaningful improvements when working with the tiny signals generated by a phono cartridge.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eLess noise. Greater resolution.

Selecting an appropriate curve can help restore a more faithful tonal balance. The P1.5 implements its equalization curves with an accuracy of ±0.1 dB.\u003c\/p\u003e\u003ch2\u003eX1 Power Supply \u0026amp; P1 Upgrade\u003c\/h2\u003e\u003ch3\u003eExplore the X1 External Power Supply\u003c\/h3\u003e\u003cp\u003eThe P1.5 can be partnered with the optional CH Precision X1 External Power Supply. Separating critical power-supply functions from sensitive audio circuitry helps reduce unwanted electrical and magnetic interference, an important consideration when amplifying extremely small cartridge signals.\u003c\/p\u003e\u003cp\u003eAt Sunny's, we appreciate products that allow customers to build and refine their systems thoughtfully over time.\u003c\/p\u003e\u003ch3\u003eA Commitment to Existing P1 Owners\u003c\/h3\u003e\u003cp\u003eOwners of the original P1 have an upgrade path to the P1.5. This involves substantial rebuilding, including new primary audio circuit boards, internal backplane, display, and product identity, rather than simply a software update.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe P1.5 upgrade program is currently expected to begin in March 2027, subject to manufacturer scheduling.\u003c\/strong\u003e Please contact us to discuss eligibility, scheduling, and personal upgrade pricing.\u003c\/p\u003e\u003ch2\u003ePricing, Availability \u0026amp; Auditions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eAll CH Precision product pricing and upgrade options are discussed personally, one-on-one, by telephone or during a showroom visit.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWe are eagerly anticipating our P1.5 demonstration unit.
