| Review: Naim Uniti Atom vs Tube Separates/Chord Digital System I can say I have not experienced any of the downsides you mention about the sound of the Atom through my Volti Rival speakers - they are 6 ohms and 99 dB sensitive but there is a lot more to matching amps and speakers than efficiency and watts. It... | |
| Review: Naim Uniti Atom vs Tube Separates/Chord Digital System @audiotroy Yes it is a great "starter" integrated/player, the easiest to use component I have ever had. To the extent that it’s a "starter" - I’ve been in the hobby for a few years and had many integrated & separates both tube and solid state.... | |
| Considering Rogue Audio or P.S. Audio Do you have any noise issues with your Rogue integrated? I constantly had hum in my speakers no matter what I did with my CM2. A shame because I loved the Rogue sound but it kept me from moving up the Rogue Audio chain. Have you thought about Line... | |
| Luxman - Shindo - Mcintosh ? I have 2 of the Luxman MQ88uSEs (basically the same as that listing from US Audio Mart). I'm running them in mono configuration from a Backert Labs Rhumba Extreme preamp. The sound is incredible, and I'd recommend you jump on that listing if you h... | |
| What does an impedance-matching issue "sound" like? Based on about 5 hours of listening tonight in vertical biamp config, I’ve gone back to running the amps in parallel.The bi-amping sounded a little smoother I think in the higher frequency. But there was an odd effect on the stereo image, seemed m... | |
| What does an impedance-matching issue "sound" like? @almarg - thanks, I have now experimented with the vertical bi-amping. It’s probably too early to have a firm opinion but as you noted, I noticed a little weaker bass, if not a smoother mid/hi top end. Also strangely enough it sounds like the ster... | |
| What does an impedance-matching issue "sound" like? Thanks Al, so this vertical biamping actually sound preferable to running the 2 amps in parallel, if I am reading correctly.So the connection from the preamp is the same as what I am using described in my post above (both L outputs to one amp both... | |
| What does an impedance-matching issue "sound" like? Thanks Al, I am curious about the vertical biamp configuration just for the sake of trying out all my options to see which sounds the best. This configuration would have benefits by running twice the output power split between the top and bottoms ... | |
| What does an impedance-matching issue "sound" like? Thanks to everyone, and @atmasphere I am glad you chimed in (was hoping you’d be lurking here :) I am using a Backert Labs Rhumba Extreme preamp with 2 unbalanced outputs (L 1 and L2 going to the left Luxman, R1 and R2 going to the right Luxman - ... | |
| What does an impedance-matching issue "sound" like? Again I have to come back to the fact that while there is a lot of discussion about what should and shouldn't be done bridging or paralleling tube amps in general, I have specific instructions directly from Luxman on how to do this, and the Luxman... | |
| What does an impedance-matching issue "sound" like? With the amp presumably now optimized for a 3 ohm load perhaps it isn’t happy driving such high impedances in the mid-range and lower treble. Or perhaps the tubes or something else in the amp isn’t well matched between the two channels, and the tw... | |
| What does an impedance-matching issue "sound" like? @georgehifi this Luxman is a push pull triode amp ... and to be more accurate I don’t want to make assumptions for the manufacturer so I cannot say they are voiced with the BP amps but they are definitely known for being paired together at shows. | |
| What does an impedance-matching issue "sound" like? Thanks guys, this is all a little confusing to me as both the speaker mfg and the dealer who sold me on running 2 Luxmans said there would be no issues. 95% of the time this sounds amazing, and I do hear the benefits of a more powerful sound and b... | |
| What does an impedance-matching issue "sound" like? Al,So if I am running the amps in this configuration to the 6 ohm speaker, you are saying based on JA's measurements and the information about the Luxman amp that it could be having a negative effect on the performance? Is it possible there is any... | |
| What does an impedance-matching issue "sound" like? Also, I confirmed before purchasing the second amp from Luxman that they could be run in mono configuration using the above setup so I am confident it is setup properly. |
