Name: Aural Twenty Plus // Mid-Century Modern Streaming Stereo Console / Custom Restoration
Brand: Aural HiFi

Availability: OutOfStock

Mid-Century style with truly audiophile performance. This set started its life as the KLH Model Twenty Plus. The only things now shared with the Twenty plus are the cabinets and stands. All of the original (very much MidFi) electronics and drivers were removed to make way for modern HiFi components. This was truly a labor of love, and no expense was spared. We restored the cabinets, powder coated the Saarinen style tulip stands, designed a custom ported speaker system utilizing Seas drivers & Crossovers from Norway, and CNC'd new baffles for them to rest in. For the turntable, we fitted a custom isolation stand for the Pro-ject T1 BT which has a built in phono preamp so that it could run directly into the 125 wpc Sonos Amp in the center console. Everything you see and need is included. This modern reimagining of an iconic vintage console is our idea of Audiophile Art, and is 1 of 1.

Liner Notes

The D'Appolito configuration offers a number of advantages over standard single-woofer designs, including: controlled vertical directivity in the midrange which reduces the effect of floor and ceiling reflections; excellent imaging and spatial characteristics; higher system sensitivity; lower distortion; and increased bass output.
