Massive power, nonexistent noise

Apos is excited to now offer the SMSL SP400 Fully Balanced THX AAA-888 headphone amplifier for sale at just $541.79 — a special 14% discount from its list price of $629.99 — for this year’s Black Friday and Cyber Monday sales events. This 14% discount will last until the end of the month only (November 30 at 11:59PM PST), so don’t wait to take advantage of this hotly awaited amp! As with all purchases, when you buy from us you get the Apos Promise for Free Priority Shipping, an Extended 2-Year Warranty, a 45-Day Return Policy, and our 30-Day Lowest Price Match.

The SMSL SP400 amp has the familiar and beloved qualities from its predecessor, the SP200, but now features all the right upgrades in all the right places. The SP400 has similar signal-to-noise and power ratings as before...and that’s a good thing. The SP400 maintains a THX AAA-888 standard of clarity, the highest possible, so you can blast your music up to a brain-rattling 134dB before you hear any hiss (even the bassheads out there are saying, “please don’t do that!”). With balanced and unbalanced outputs, the SP400 can power nearly whatever you own: it drives 12W at 16Ω and 6W at 32Ω, but there is also a three-position gain toggle that can put an extra three to six decibels on top for you.

As for its improvements, the SP400 now sports a large 1.9” LCD display screen, comes with a full-function remote, and features a fully balanced output for its preamp mode. Aesthetically, the SP400 makes the perfect pair with the SM400 DAC, so you can create the latest SMSL stack.

If you know that stack is what you want, Apos has you covered: we are pleased to offer you the SMSL-400 Ensemble!
