  1. Just purchased my first DSP. Wrote a little mini review or just shared some of the initial hiccups I encountered and remedies which hopefully may help others.

  3. hi there is your amp still for sale? and will you post to uk ? thanks Oz

      Hi, I no longer have the amp. After contacting Emotiva they allowed me to return the amp to them. 

  4. Spent a few hours tonight listening to the Parasound Halo A31. By the end of the night I realized these two amps are totally different. The sound from Parasound is like warm butter spread over soft bread whereas the Emotiva is like cold butter spread over toast. If the Parasound "colors" audio then I love the painter of Parasound. I'm in audio bliss at the moment.
  5. Just a note Emotiva has wonderful customer support and service. They allowed me to return the amplifier by making an exception beyond the trial period. The Emotiva DR3 is no longer for sale.
  6. Price reduced by another $100.00 dollars. That's $1400.00 a savings of $600.00 on a less than two month old Emotiva DR3!
  7. Selling one Emotiva XPA-DR3 that was purchased on January 27th 2020. No manual but original boxing and birth certificate. You pay shipping and insure if you wish but you arrange pickup [easy through UPS]. Amp is in perfect condition. I prefer Zelle payment from your bank to my bank [no fees] but I will accept PayPal. I'm located in Idaho, Nampa and if you need exact address for shipping please message me as I will provide my address. Asking price $1500.00 [Transferable warranty]. Amplifier sits underneath an AcInfinity cooler. Full Specs available here: https://emotiva.com/collections/amps/products/xpa-dr3 Power Output (all three channels driven): 450 watts RMS, per channel, into 8 Ohms, at <0.1% THD. 600 watts RMS, per channel, into 4 Ohms, at <0.1% THD. Power Bandwidth (at rated power; 8 Ohm load): 20 Hz to 20 kHz (+ / – 0.1 dB). Broad Band Frequency Response: 20 Hz to 50 kHz +0/-2 dB. THD + noise: < 0.008%; at 100 watts RMS; 1 kHz; 8 Ohms. Signal to Noise Ratio (8 Ohm load): > 120 dB; ref FTC rated power; unbalanced input (A-weighted). > 96 dB; ref 1 watt; unbalanced input (A-weighted). Minimum Recommended Load Impedance (per channel): 4 Ohms (which equals one 4 Ohm load or two paralleled 8 Ohm loads). Damping Factor (8 Ohm load): > 500. Input Sensitivity (for rated power; 8 Ohm load): 2.0 V. Gain: 29 dB. Input Impedance: 33 kOhms (balanced). 23.5 kOhms (unbalanced). Below is a picture of the DR3 as is at the moment. The amp went directly from delivery box to this location and never has been moved. The amp is in perfect shape. I want to sell this amplifier so if you see it not selling and want to make a reasonable offer please message me. That is, I'd like to sell this amp and not sit on it. Thanks, William
  8. Thanks firedog, That'd be ideal. My only hesitation is being locked [ethically] to the local dealer which is demoing me the amp. I'd feel bad if I demoed their equipment and bought elsewhere online for lesser price. Though, demoing the equipment might save me money if the seller I'm looking at this time doesn't have a return policy to demo the equipment. I'll ask. Thanks Shawn, The reviews I have read said there is no audible difference between the A21 and A31 only another channel. As far as dynamics that's what I'm hoping for. I prefer class A and I think the Parasound A31 is class A up to 7 watts. Have read conflicting information on this as two different reviewers stated 7 and 10 watts. Either way I am prepared already having a dedicated powerline for the amp on a 20a circuit. Besides the various remote turn on options I like the variable input sensitivity of the Parasound. Thanks for the feedback fellas, William
  9. Hi, I currently own an Emotiva DR3: https://emotiva.com/collections/amps/products/xpa-dr3 I'm in the middle of purchasing a Halo Parasound A31: https://parasound.com/a31.php The manufacturer of my speakers [Tekton] seemingly love Parasound and I've run into many positive reviews about them. Actually, there's a lot of "familiar language" when reviewers describe the Parasound amp that was used for the Tekton Ulfberhts. And I also note that most reviewers don't compare the Parasound to lesser costing amps but moreso including the likes of McIntosh. I have to admit I'm looking for a bit of verification. In so doing I thought to drop the audiophilestyle community the topic question and get your thoughts on these brands and specifically these amps. Thanks a bunch! William
  10. Hi, There's a few songs in my collection that sound wonderful. I'd like to be able to play the song on my computer and analyze the song because I'm curious to where the bass frequencies are. Of course these are from Youtube but the CDs sound excellent on my system and since they sound much better than "other" recordings I'm curious as to why. If you could recommend any freeware software I can download into Windows 10, play, and watch a spectrum analyzer in order to point me at the frequencies I'm hearing that'd be great! Jesse Cook, Album: One World, Track: TOMMY AND ME That'll give the subs a work out. The album is very well recorded. Jesse Cook, Album: Beyond Borders, Track: Skip the moon The track just sounds wonderful in the midbass to midrange though there is a sense of "eerieness" about the song. I enjoy the "springyness" of the nylon guitar strings and the resonance from the guitar body. I actually love this song for SPL. When the guitar begins "climbing" upwards in scale I've had listeners leave the room as the hairs stand up on the back of their necks. Jesse Cook, Album: Beyond Borders, Track: Call to Rythm. Love the bass drops. Let's Tango. The room is spacious.
  11. Probably a no brainer to most here. Amazon Music HD was continuously disconnected until I performed a simple Wifi channel change. Began by observing what Wifi channels my neighbors were using: https://www.disqus.social/2020/03/tip-stop-amazon-music-hd-streaming.html

    Found a cooling solution to help keep the amp within desirable temperatures and extend its life:

    Newbie to REW

    Hi, I'm looking to install REW and use it from another room to the listening area. Thinking about a calibrated microphone and 50 feet of USB cable. I'd like to measure the listening room as well as the entertainment system with the program to help make adjustments. Question, for output of a test signal what's the best way to send a signal to my entertainment system? 3.5mm to RCA? Any suggestions for a newbie that might make life easier or learning REW more simplistic? Thanks, William
