Sorry but you two have much to learn.
You can’t fathom it for yourselves, you just mimic what your been told by who’s selling them to you.
That’s enough .
Pass X150.5 or Odyssey Stratos monos?
After months of research and mental anguish ;) I've narrowed down my search for new amplification to the two in the title. There are obvious differences like the fact that one is a stereo amp while the other are monoblocks. Anyway, if you had to, which option would you go with and why? Thanks!

Do you think that’s all it is, driving a dummy load resistor? you have a lot to learn. And a non bridged amp will drive a 2-4ohm load better than the same amp bridged if you’d like to know. Don’t you guys think a designer like Nelson Pass would have just bridged amps like his stereo X250 to make his mono X600????? or his XA30 stero to make his XA100 monos??? |
You need to educate more, https://ibb.co/x5CGWHQ Better still find "just one amp designer" that doesn't bridge amplifiers to sell. To back bridging to have the same quality measured specs as the same amp non-bridged, into todays high end quite hard to drive speakers. |
Whatever 🤦♂️ get someone to show you on the test bench, where all decent amps are designed/measured and worked out. It’s a very easy way for a manufacturer to have a much more "powerful mono pair model" without much re-designing and tooling put into doing it, like the original stereo one usually does |
You honestly have no idea what your on about, if it were just about wattage, just go get yourself one of these 4000w!!! for $450!!! and you’ll be happy. https://www.amazon.com/Behringer-NX6000-Power-Amplifier/dp/B07JJKV6JH So what you’re arguing about is applicable for true mono amps only, not in this case, Odyssey stereo-to-mono amps."True mono amps" don’t have a problem, only stereo amps that have been bridged to be monoblocks have worse specs. As you can see this is a Stratos monoblock extreme "was clearly a stereo amp" that has been bridged to be mono, as I’ve shown with the two large left and right channel red circled, and the one set of input and speaker terminals omitted small red circle https://ibb.co/kG04kTv |
So, please @georgehifi stop BS about Odyssey if you even didn’t listen or test those amps. Sorry but obvious, if you knew but don’t, what happens to all measurable parameters that make for good amps, they all go backwards when an amp is bridged (mono'd), only the wattage is higher, everything else takes a hit. Cheers George |
why are you so negative against the Odyssey amplifiers? You really need to read more sunshine/mate/bro. I’m only anti the monoblocks that are just mono’ized stereo amps (not true mono amps at all). NEVER!!! have I said anything against the stereo amps. The gullible here think the mono’ized stereo’s are better than the stereo amp. Only in wattage being far higher are they better, no where else. Sound quality into the same speaker that both have enough wattage for without strain, the stereo amp will, without a doubt sound better! BTW: Cerwin Vega D9, 101db 8ohm load, 125db before they distort. Yep! your on the money🤦♂️ |
Hifigeorge: but anything Odyssey that he ever mentioned is negative. This is incorrect, only the stereo’s that are made into monoblocks Klaus. The stereo’s amps I’ve said sound quite good if you search. This was after my friend who was going to be your Au dealer saw had me check them out. After I pointed it out to him when he lifted the lid in the samples he got, the Monoblocks were just a pair of the stereo’s monoblock’ed, when he showed me the inside. As for the stereo sample he got at the same time, I said to him it should sound better on the speakers we had, 89db-90db but a hard impedance load, and it did. So Klaus I only put **** on the monoblock’ed stereo’s amps, not the stereo amp. George |
I’ll keep mine until I have the $20-30K to buy a Pass product. Don’t know where you buy used Pass X150.5 that we're talking about here, but they go for $1500 to $3000 all over the place. https://www.hifishark.com/model/pass-labs-x-150-5 Cheers George |
almarg Al have a close look at my first post links to the "Stratos stereo" and then the "Stratos mono", and I’ll see if I can get some better shots if you still can’t see it. This is better shot of the stereo The Stereo https://ibb.co/0yHZFTM The Mono has a transformer case and some extra PS caps around it, but it’s a bridged stereo Stratos https://ibb.co/9ZqDw18 Cheers George |
nothing wrong with a bridged amplifier if done properly!Really? then please show how to bridge this common simple Nelson Pass Threshold S300 amp "properly" so it’s just as good as the stereo version. https://imgur.com/we3VoER |
I actually owned a pair of Odyssey Audio Kahrtargo monoblocks and found they were horrible in my system. It was because of this, your Revels looked like a 2ohm load to the bridged Kahrtargo monos and probably were going unstable. https://www.stereophile.com/images/714R208fig1.jpg Cheers George |
whatsmyname OP
You make what could be a good stereo amp into a mediocre mono amp by bridging the two stereo channels together to make a mono. Yes you gain a lot more watts, but everything else that makes for a good amp takes a hit. Current ability is less Stability is less Distortion is more Damping factor is worse The ability to drive low impedance’s is reduced by half. I’m sure there are more. Cheers George |
whatsmyname No contest, Pass X150.5 as it's it's not a bridged amp, like the Stratos mono's are Stratos Stereo http://www.odysseyaudio.com/pictures/amp-stratos-st-xt.jpg Stratos Mono https://img.usaudiomart.com/uploads/large/181185-odyssey_stratos_mono_extremes_with_upgraded_red_boa...
