A Reference LE Class Multi-Channel Amplifier
The NuPrime MCH-K38 is a Reference LE class multi-channel amplifier designed for uncompromising home theater and music listening. With its quality parts throughout and an advanced 550kHz switching amplifier operation, the MCH-K38 delivers a full 210 watts into 4 and 8 Ohms per channel. Each pair of output channels can be bridged to double the power to 400W at 4 and 8 Ohms. The NuPrime MCH-K38 comes with 8 sets of RCA and true balanced XLR inputs. A self-resonant design, the amp's 550 kHz PWM switching frequency constantly adjusts to the input signal, output current demands, and loudspeaker impedance variations. Exemplary speed, accuracy and exquisite dynamics nicely describes NuPrime's signature sound.
The MCH-K38 amplifier is derived from the ULCAM (Ultra Linear Class A Module)+Class D design first introduced in IDA-8. By joining a powerful high impedance single-ended amplifier circuit in the preamp stage with a well integrated Class-D power stage, the MCH-K38's rich tube-like sound and tremendous speed is sure to impress audio enthusiasts. By utilizing a 1000W power supply and CMA capacitor array, the MCH-K38 fully exploits the Class A+D design's ability to deliver massive amounts of power and speed when needed by a single or multi channels.
The NuPrime Sound
- Vast soundstage
- Wide, lightning-fast dynamics
- Ultra-low distortion and noise
- Music emerges from a pristine background, with delicate details and nuances intact
In summary, NuPrime's sonic character stands well apart from - and indeed above - the soft, cushy sound we often associate with most tubed amplification or the dry, edgy sound we often associate with solid-state and switching technology. Rarely does an amp achieve an ideal balance of richly textured timbres and harmonics, bottom-end authority, startling dynamics, exquisite low-level detail, and a fully revealed, fully dimensional soundstage against a backdrop of mile-deep silence.

Buy&Try applies to the entire Aune, Auralic, Quadral, Sbooster & Taga range.
Buy & try gives you as a customer the opportunity to try out the product in your own home environment, instead of standing in a stressful store and trying to form an opinion. Rooms behave very differently and affect the sound in different ways and we give you the opportunity to demo the product for a full 30 days, in your own home.
If for some reason you feel dissatisfied, just contact us and we will help you with the return shipping, you can also take advantage of our shipping agreements with lower prices. Costs that will be charged to the customer are the shipping to the customer and the return shipping to us at MYC HiFi. For return approval, the item must be returned in new condition and in the original packaging.
Regarding speakers, be aware that speakers may need a long recording time to come into their own. After a couple of hours you can usually get a taste of what to expect, but a speaker deserves 100h+ before serious listening. The speakers we sell with ribbon tweeters need several hundred hours before they start to sing. So feel free to leave the speakers on around the clock so you can quickly accumulate hours.
If you have any questions or concerns, do not hesitate to contact us.
- Buy & Try applies to goods that are normally kept in stock and not to order goods, unless otherwise agreed.
