Denon

In exclusive partnership with top-tier modification house Parts ConneXion, Underwood HiFi is proud to offer the following carefully tested performance enhancement packages for Denon universal players: DVD-3800BDCI, 5910 / 5900 / 3910 / 2910 / 2900 / 2200 / 1920

We also just added a modification to the DenonAVR-3805 and AVR-4308ci receivers. By virtue of selling consumer-direct, we can offer these super-charged, brand-new models for a better price than the same modifications

Denon 4308The Denon AVR-4308ci is an excellent A/V receiver feature laden with all the most up-to-date video features. It decodes all the new hi-rez formats and offer multiple v1.3a HDMI inputs. Our receiver mod is for the audiophile who wants a one-box solution but also the sound quality that approaches quality separate audio components.
Denon 3805Our brand-new Denon AVR-3805 receiver Level 2 modification We have played with the Denon AVR-3805 receiver and believe that it is a superb value for its $1200 retail price. It outperforms all the $1500 models from the competition.

Denon DVD-1920 The Denon DVD-1920 has progressive scan processing using the DCDi Faroudja circuitry. It also uses digital bass management. This player offers HDMI upconverting video outputs that are HDCP compatible. It will take standard DVD and output a 720P or 1080i High Def signal.

Our Level-1 modified DVD-2200 is a wonderful entry level multi-player for those audiophiles that want to spend less than the 2900 The Denon DVD-2200 starts life as a universal (CD Redbook/SACD/ DVD-Audio) multi-player that is an exceptional progressive scan video player and uses some of the best available digital parts (Burr Brown 1790 series) for audio. The 2200 uses the DSD-1791 DAC. The analog-stage however is a major disappoint-ment. The results are an excellent video player that's mediocre on audio.
