upgrade from Audio Physic Spark



I recently upgraded my amp to McIntosh MA2275 tube integrated amp and want to upgrade my Audio Physic Spark speakers as well. Due to space constraints, I need a low profile floor standing speaker or a bookcase speaker. I'm currently considering Wilson Audio Duette and Sonus Faber Guarneri. Will I see a drastic improvement in sound with these upgrades? Any other speakers I should consider around 10K range? Thanks.

10K is a *lot* of money, I don't care who's spending it. What's your room like? These days, at that price-point you could buy almost anything and it would sound amazing. These days most 2k speakers sound amazing. I mean no disrespect in asking, but I'm just emerging from the same cart - before - the - horse frustrations (albeit at a smaller budget), and in my case a set of room treatments and slightly more attentive placement are doing amazing things. And you know what they say about recent converts.

So, not knowing whether you've already got some uh-MAY-zing listening room, all custom bass traps and corner tunes and whatnot, or just a rig parked in the middle of a family den, my visceral reaction to the question, based on my own experience, is to audition some comparatively easy-to-drive speakers at a fraction of your intended budget, and spend the rest on dedicated power, cabling, and room treatments.

Again, I mean no disrespect when I make this suggestion. For all I know, you could "lose more money than that, runnin' for the bus," as Mickey from *Snatch* would say, and your room could already double as a speaker-testing lab. But after the experience I've just had, I can't imagine a speaker out there that's worth the extra seven grand over a Spendor s8e or a Devore Gibbon 8 or a Joseph Audio RM25si-mkII, with that kind of quality amplification and a really optimal room setup.

...You could also spend some of the leftover money on a new front end, if you're not already SOTA, there.

ALL of that being said, the price-is-no-object speakers that most impressed me in various shops were made by DeVore and Audio Physic, with the DeVore's doing a better job of soundstage and the AP's sounding just a tad more musical.

But I still think you should spend three grand on the speakers and the rest on the room and the associated gear -- a reaction worth exactly what you paid for it, no doubt.
Dog or man thanks for you comments. To give you more color, my listening room doubles as a library and the room dimension is about 12'x11'. Currently I'm running:

- McIntosh Tube Integrated MA2275
- Rega Apollo for red book with Nordost Blue Heaven interconnect
- Marantz SA-8001 for SACD with PS Audio Xstream Resolution interconnect
- Audio Physic Spark speakers
- Nordost Super Flatline MKII speaker wires
- PS Audio prelude AC power cable
- Transparent power conditioner (Power Bank 2)

Given that I have a bookcase behind the speakers, the speakers stand about 3' from the walls and the bookcase helps with reducing reflections. I just upgraded my amp from solid state integrated MA 6300 to the tube and saw a huge improvement in how music sounds much more natural and easy to listen to for hours. I wasn't sure if I'm short changing the amps by using substandard speakers compared to the amp. But I agree with you. I've auditioned many speakers ~10K (Wilson Audio Sophia, Duette, Sonus Faber, B&W, etc.) range but I haven't seen as clear improvements as my previous updates (I just got into this audiophile game early last year). However, Wilson Audio Watt/Puppy was amazing but it's out of question at this point.
The three speakers you mention are very different but they share in common being nice WAF friendly furniture...is that what you are looking for...something aesthetic?
