jdm56 Posted July 31, 2003 Share Posted July 31, 2003 Sony is bringing out a new line of ES receivers. In fact the bottom model is available now at Crutchfield, and I've seen the bottom two models on the J&R website. At least some of the top models in the new line (STR-DA3000ES, 5000ES and 7000ES) have "digital drive" amplifiers which I assume are indeed digital, or "switching" amplifiers. Is this correct? And, is it just me or does there appear to be a bit of a trend towards digital amplification in the "mass-market" A/V receiver category, what with Harmon-Kardon's and Panasonic's digital offerings of late? And speaking of the H-K digital receivers, what's up with their on again / off again appearances on the Crutchfield site? Has anybody else noticed that? One more question: Do digital amps have a signature sound? I've never heard one myself. Really the last question: How in the heck does Sony reconcile analog-out only SACD with digitally amped receivers? Is that moronic or what?

marksdad Posted July 31, 2003 Share Posted July 31, 2003 i do not know much about the new products, but it seems to be typical sony hat tricks, anything for a dollar Quote Link to comment Share on other sites More sharing options...
jnorv Posted July 31, 2003 Share Posted July 31, 2003 For $100, I bought an 8 watt/chan TriPath digital amp evaluation board. Input is 12 volts DC. Sounds pretty good. I use two of them to biamp my horns. http://www.tripath.com/audio.htm Jim N Quote Link to comment Share on other sites More sharing options...

jdm56 Posted August 1, 2003 Author Share Posted August 1, 2003 I do recall a very positive review of a $10,000 Sharp digital amplifier, that appeared in Stereophile a while back. For 10k, I guess it ought to be good. Sony hat tricks? Come now, you know Sony is only interested in advancing the state of sound reproduction for discriminating audiophiles! H-K has had a couple of digitally amplified A/V receivers that have been playing "now you see me; now you don't" on the Crutchfield website over the past few months. Hence, my question. My presumption was that perhaps they were having some problems with them, but I don't know. Sow how does Tri-Path digital amp "sound"?

jnorv Posted August 1, 2003 Share Posted August 1, 2003 Well they dont really have a sound. Do a search in 2 channel on tripath. Leok has done extensive work with them. He suggests some mods to the eval boards for better sound. I am just running them as they came from the factory, since I am an ME and am electronically challenged. I use them for background music during the week. For serious listening I use a 300B SET for the HF and a Rowland 5 for the LF. I think that that sounds better but not by much. Idle power is 0.6 watts. At 100 db, using 288s on 1005s and 515Bs in 828 cabinets, I see maybe 2.4 watts draw. Jim Quote Link to comment Share on other sites More sharing options...
