Product Description

Modwright KWH 225i Integrated Amplifier Beta Units

Save $2495 on Beta Units

"We combined solid state output stage of our Reference KWA 150SE amp, with the controls and integration of the KWI 200. We then replaced the SS preamp circuit with a Class A tube design and increased the power to 225W. The result is the KWH 225i." - Dan Wright

Features:

  • 25 watts Class A
  • 225 Watts Class A/B
  • Zero Negative Feedback Solid State Amplifier
  • 6922 Tube Based Preamplifier

The Deal:

Modwright has a very limited quantity of beta KWH-225i integrated amplifiers. These were sent to dealers and beta testers for evaluation and feedback. Modwright is now offering these beta units for sale at nearly 30% off of retail pricing. 

All run perfectly, and are cosmetically in 9/10 or better condition. However, due to these being beta units there are some minor issues. One being an error on the silkscreen on the back panel and  another being the slight bowing at the front top portion of the cover, due to an error in the mounting holes by .050.

 
All units are without options. Meaning no phono stage or DAC. They will come in full factory packaging, with a full factory warranty and full upgradeability for future updates.

Hybrid Design In Modwright's DNA

The Modwright KWH 225i hybrid integrated amp represents the culmination of years of solid state and tube preamp/amplifier design. Modwright has from it's very beginning preferred a hybrid approach to system building. Combining the natural richness of tube preamplifiers with the grip and punch of solid state amplification.

The KWh 2225i hybrid integrated amp is a natural extension of this philosophy. Combining the solid state output stage of Modwright's Reference KWA 150SE amp, with the controls and integration of the KWI 200, then replacing the KWI 200 solid state preamp circuit with a Class A tube design and increasing the power to 225W. The result is the KWH 225i. 

Our Take on the KWH 225i

This is perhaps Dan's best work yet. The KWH 225i has gobs of power for when you need it, but is biased to run in Class A for the first 25 watts. This means that for most of your quite to moderate level listening, you are in Class A mode, only slipping in to Class A/B when you turn it up to louder levels. The tube preamplifier section is dead quiet. We actually preferred the stock JJ 6922 tubes to the more expensive Ampex. Dan voiced the amp for just the right balance of warmth and neutrality. We use it with the Spatial Audio X3's in our Studio and the sound is gorgeous. Wonderful tone and dynamics, holographic soundstaging and pinpoint imaging. We rarely run it out of Class A mode due to the 97 dB efficiency of the X3's. The integrated itself runs warm, not hot at all due to ample heat sinking.

The Modwright KWH 225i closes the performance gap between separates and integrated amplifiers. You really need to hear this!

Class A Operation, Zero Negative Feedback

The Class A preamp stage, with 25 watts of zero negative feedback Class A output from the amplifier section will be a fantastic match for efficiency speaker designs. Even lower efficiency speakers will benefit from the high current 225 watts of Class A/B output.
