Add to this, beautiful high-end Japanese design, and you have one of the most desirable amplifiers in the world. \u003c\/p\u003e\n\u003cp\u003eFollowing the powerful MA-1500 monoblock that uses the revered 300B vacuum tube, Phasemation launched a 300B stereo integrated amp in 2024.  The SA-1500 is a pure class-A self-biased design with an output power of 9 W.\u003c\/p\u003e\n\u003cp\u003ePhasemation made four \"commitments\" when they designed the SA-1500. Commitment 1 was that it must be pure class-A, prioritizing sound quality regardless of the effort it takes. As Phasemation puts it, \"Class-A sound is pure, with a delicate expression, and has vast audio advantages due to its low distortion.\" \u003c\/p\u003e\n\u003cp\u003eCommitment 2 was to not use negative feedback, as Phasemation's extensive listening tests showed that zero feedback made for a more dynamic and expressive sound.\u003c\/p\u003e\n\u003cp\u003eCommitment 3 required the use of triode tubes. Phasemation believes there is nothing nostalgic about the sound of vacuum tubes, and that it brings a profound sound impact that can be enjoyed even with modern music. 9 W may not sound like much, and is not much with solid-state, but with tubes and their huge current delivery, 9 W is huge, and can drive a range of loudspeakers.\u003c\/p\u003e\n\u003cp\u003eFinally, Commitment 4 was to follow a monaural design structure. By separating left and right channels, Phasemation keeps crosstalk and other cross-channel effects to a minimum, resulting in excellent imaging and stereo separation.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNo feedback design for rich, direct, dynamic sound\u003c\/li\u003e\n\u003cli\u003eIndividual left and right output transformers made by Lundhal of Sweden\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eIndependent left and right choke transformers for less crosstalk \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDirect mode allows for use as a power amp\u003c\/li\u003e\n\u003cli\u003eLow-noise, anti-vibration design featuring thick glass and rigid aluminum\u003c\/li\u003e\n\u003cli\u003eExtensive shielding on power transformer, choke, and output transformer\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eUses 6SN7 in the first gain stage, with the 300B as the output tube\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003e Input Impedance: \u003c\/b\u003e 47 kΩ\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e Gain: \u003c\/b\u003e 30 dB\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOutput Power (THD 5%): \u003c\/b\u003e 9 W \u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e Output Impedance: \u003c\/b\u003e 4–8 Ω\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e Power Consumption: \u003c\/b\u003e 140 W\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e Dimensions (W x H x D): \u003c\/b\u003e 16.93\" x 9.45\" x 14.96\" (430 x 240 x 380 mm)\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e Weight: \u003c\/b\u003e 39.68 lb.
