Higher powered but efficient amp with the imaging of a Pass XA-25?


I had an XA-25 for a trial driving a pair of Spatial X5’s (97db efficiency). That combo produced imaging depth like I have never heard before or since. But my room is big at 25 x 25 feet and the Pass couldn’t cut it at reasonable levels (too noisy). Now the Spatials are gone, using KEF Reference 1 with Rowland 535 monos. The KEFs are NOT efficient (85 db) and require some real grunt from an amp.

Does anyone know of a high powered (200-500 W/C), high current, balanced amp that is reasonably efficient (unlike Pass) and which can produce the layered depth and finesse of the XA-25? I do not want to go all tubes in my power amps. Hybrid is OK.

I have ordered a tube preamp (Rogue RP-7) to replace my Benchmark LA4. I think that will help but I doubt it will get me all the way there.

Thanks in advance.

@russ69 If I do it will be for a pair of Joseph Audio Pulsar2 Graphene, Fritz Cararra Be, Sonos faber Olympica Nova, or maybe Harbeth 30.2. As you can see I like stand-mount speakers. I think you would be surprised at what I am getting from these KEFs with the Rowland amps. The room is more energized than it ever was with the Spatials. But I know I can coax more from them.

@artemus_5 See my lengthy post from earlier this morning. Yeah, I know about Sachs and Spatial. They are excellent speakers, superb really, just can't live with the limitations. I tried.

@soix Thanks for the recommendations. I will look into them.

@jayctoy Do you have direct experience with these amps driving speakers in the Reference line? Tell me more, like sonic characteristics with these speakers.

You got that right!!!  I’m with you brother. 

Russ +. Nailed it.

Three out four of yours are good choices for new speakers.

I am buying one of them now.

I would swap the SF Olympica for the Amator Electa III.

That would be my ideal choice of those 4. Add a couple nice little RELs

and you are up by 200% from where you are now.
