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!

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.

I would disagree with you regarding my speakers/amp combo. Actually at the time my speakers were Dali Rubicon 6's that actually had a nominal impeadence of 4 ohms when I aquired the Kahrtargo monoblocks. The Kahrtargo monoblocks had a input impedance of 10k ohms 
My Dehavilland UV 3 had a output impeadence of 800 ohms so that was the deal breaker. At minimum my Dehavilland needs to "see" 18K ohms per Kara at Dehavilland.
Happy Listening

The bridged ones, would have been crap also into your Revels as well for the reason outlined.
And as for pre to power impedance, I don’t see 800 ohms into 10000 ohms such a bad mismatch either.

I'd go with Pass. Pass amps are recognized by MAGNEPAN, as the "go to electronics, when it comes to driving "MAGGIES" . Superlative in every respect. You might also consider PASS monoblocks and pre-amp if your budget can stand it. I am confident you will thank yourself.
I have Odyssey Kismet Monos (In Kartango Cases) & they are fabulous.  Significantly cheaper than Pass & with somewhat better Specs in Damping Factor & Slew Rate, which are important in Bass & Slam.  I do use Sub Woofers, as I am somewhat of a Bass Freek.

Pass is a Class act, but Odyssey Monos will stand up to Pass, check out this review of Kismet Monos ~ https://6moons.com/audioreviews/odyssey2/1.html

Mine are driven by an Assemblage Pre-Amp; both Amps & Pre-amp were purchased used, @ significant savings.  Amp SN's are in the 52xx range & may even have better parts than those reviewed in the link above, as Klause of Odyssey is continually improving his products.

When I got the Odyssey Amps, I used my existing 8 Foot Twisted Silver Plated Copper Cables on my Anthonney Galllo 3.1's  Later, I replaced these with 3 Foot, 20 Gauge, 5 Strands ,Twisted Pure Silver Wire with Teflon shielding  (wound myself from wire of which I had bought some 30 Years ago).  WoW did the HIGH Frequency Response Jump out!

Yes, a big advantage of Mono's comes from using Much Shorter Speaker Wires!

Best of Sound as you continue your quest for Audio Perfection.
