Where are the pictures of the amps that some of you bought cases for? Let's see them!!!
BarryTom did not sell these directly?? I thought it came from his web site?If he didn't sell this direct then I really appreciate him taking the time to fix it, he's charging me for it of course but still, awfully nice
I've ordered the Connex SMPS500R power supply that avionic mentioned for my cda-254. If it performs well, it'll free up some space in the enclosure for me to maybe add a LDR kit to the dcb1...http://connexelectronic.com/product_info.php/products_id/118?osCsid=5t1u9gs3oaj7fnjenmriiqv185
I have received a few PM's asking about the smps500r. Hopefully this answers your ?? if not feel free to shoot me another pm.The smps500r sounds great. I did notice when driving a certain set of monitor speakers that I built, that the 500r couldn't keep up. The speakers are Danny Ritchies (GR Research) anarchy design. Sensitivity is around 84db . Those anarchy mids really need some power to get playing loudly. Definitely not the easiest load for an amp and power supply. Matter of fact these speakers fried one of my nuforce 8b,s. Love these speakers by the way. While playing at very loud levels I noticed that the left speaker would cut in and out. At first I thought it was maybe a bad solder joint of mine. Hooked up the linear power supply and no problems at any levels. I plan on using the smps500r for a 5 channel class d audio amp that will be driving PSB Image speakers with 93db sensitivity. I really do not think I will have any issues. All in all I am very happy with the smps 500r. It is small 4"x4" and gets rid of both the transformer and power supply board of the linear PS. Hook up is a breeze 3 wires in and 3 wires out. Just be aware if you are driving difficult loads at very loud levels you may run into some issues. Attatched is a diagram of the 500r circuit board for wiring reference.
Hm, with its specs, the SMPS shouldn't have had an issue with the Anarchy... It acted as if the smps just didn't have the capacitance to keep up. 2x63v 6800uf
I also have found a 3-4dB gain discrepancy between the 2 channels on my CDA-254. Anyone else have this issue? It is a real bummer to have the entire soundstage shifted.
@jwtrace - The CDA series does not have gain pots.
As my buddy in the U.K would say...You're F---ed mate!
Another question, which I have asked before: Has anyone come up with a tube buffer that can PROPERLY drive the CDA series amps? I'm not having a lot of success. Cathode followers and SRPP circuits mostly don't like loads under 20K and the result is a loss of extension at the extremes and some odd coloration.The CDA series has an input impedance around 7K, or so I've been led to believe.Input anyone?
