The Best of Both Worlds

The Massdrop CTH + SDAC DAC/amp brings two of the community’s favorite designers together in one affordable, easy-to-use package. It features the Massdrop x Alex Cavalli Tube Hybrid Amp (or CTH), built from the ground up by the founder of Cavalli Audio—a legend in the world of headphone amps. For the DAC section, it uses the Massdrop x Grace Design Standard DAC (or SDAC), a collaboration with a company long known for its incredibly accurate, transparent studio gear. The result is an all-in-one unit that measures objectively well and works with a variety of driver types and impedances, including all previous Massdrop over-ear headphones.

About the Massdrop x Grace Design Standard DAC

The Standard DAC sets a new standard in entry-level DACs. Designed with the objectivist audiophile in mind, the SDAC delivers objectively good performance meant to meet or exceed the measurements of the popular ODAC while retaining many of its other benefits. It’s equipped with the new AKM AK4452 digital-to-analog conversion chip and can process the most common file types up to 24 bit/96 kHz with no harshness or edge and the kind of resolution and detail that’ll make you want to listen on and on. It runs off of USB bus power with plug-and-play operation, which means you won’t need drivers or any special software to get started.

About the Massdrop x Alex Cavalli Tube Hybrid Amp

This hybrid amp combines a solid state section, a tube amp section, and an entirely new circuit design. A complete revision of one of Cavalli’s early DIY designs, it delivers the current required by planar magnetics, along with the voltage drive that dynamic headphones need to perform their best. It’s quiet enough for sensitive headphones like the Massdrop x Fostex TH-X00 and powerful enough for higher-impedance headphones like the Massdrop x Sennheiser HD 6XX. With the supplied 6922 vacuum tube, the sound is smooth, natural, and resolving with precise detail and just a touch of tube character.

You can check Tube Depot. I highly recommend the 5670W on a 6922 adapter, it is leaps and bounds better than most 6922, and dirt freaking cheap.Read More

Absolutely: You can use the DAC output straight to THX. I am currently using the DAC output to independently drive my powered speakers, and the CTH can be powered off too! However I did notice the...Read More
