Jimmy, I've used both the Delta-44 and the FA-66 with the 1000. As for the 5K, I can only judge by the ones I've heard on the air and my own, and whether I use a PR-40 or an HC5 cartridge, it sounds very good, with no trace of audible distortion. I listened to Jeff's recording and I agree that the second half of the recording sounds quite bad. I'm only saying that I have not heard that on the air, and certainly haven't heard it from my 5K. For that reason, I wouldn't expect that the problem is due to any inherent shortcoming in the DAC, or all FLEX-5000's would sound that way, and they do not.
Regarding the monitoring setup, I've used the Icom 746PRO set to it's 3.6K 'Sharp' bandwidth, while monitoring the audio from the rear panel (cleaner and wider bandwidth than the headphone jack) with several pairs of headphones, including (at various times) the following models: Beyerdynamic DT-880 Beyerdynamic DT-990 Grado Labs SR125 Grado Labs SR325 The monitored audio has been very clean with all of them, with no change in character regardless of whether I run 1 watt or 100 watts. I'd be happy to set up a sked sometime to run some comparative tests. 73, Dale WA8SRA Jimmy Jones wrote: > It's certainly your right to disagree Dale but I've heard the same > comments from two of the best ears that I know.
