Denon 5803 vs Sony ES9000 Receivers

<font color='#000000'>How do these two compare? &nbsp;I read the excellent review of the 5800 and mention of the Sony ES in several topics but no review!?!</font>

The new Sony Digital receivers are just coming out. &nbsp;They look very promising and we are hopeful to get our hands on one for evaluation soon.</font>

<font color='#000000'>One thing that really stands out on these new Sonys is there horrible specs (on paper). &nbsp;The new 5000ES receiver has a THD rated at .6! &nbsp;Same for the 3000ES. &nbsp;The 9000, a $4,000+ receiver is a bit better at .15, but that is about what I would expect from a $200 receiver. &nbsp;The least expensive of the new ES line, the 1000ES has the best rating (.09). &nbsp;What gives? &nbsp;Does this have something to do with the new digital amps? &nbsp;Do they somehow give false measurements?</font>

This higher distortion most certainly has to do with the digital amps and/or possibly the power supply. &nbsp;We also wonder just how good the SNR is and if the passive LC output filters will have deleterious effects on fidelity when presented with a reactive load such as a loudspeaker.</font>

<font color='#000000'>I think you have put in technical terms exactly what my concern is. &nbsp;Is this thing going to sound digital? &nbsp;When the first CD players came out we were all very excited about the &quot;clean&quot; sound until we listened more. &nbsp;It was awhile before the manufacturers started worring about the D/A conversion. &nbsp;After all we hear analog in the end.</font>

<font color='#000000'>From agoraquest.com forum. Many people reported they have hissing problem with the 3000ES/5000ES at high volume and actual power output is far below the spec.</font>
