I’m a great believer in less is more, because you can focus more on quality. If you like Dipole speakers and that wall of sound, and have plenty of power bi-amping, you could get into a pair of Maggie 20.7’s for under $10k used. They’re better value than used ML CLX’s and i’d argue sound better dollar for dollar than used Apogees.
New speakers for my system
I am currently running a bi-amped system comprised of a pair of 360° dispersion transmission lines that are tuned to 17Hz and a pair of 2 ways using Scanspeak Ti HF and 6" full range drivers. The 2 ways are crossed over at 4k with 2nd order Butterworths.
I am driving them all with a pair of Classé strereo amps. The crossovers to each amp are via a DSP.
The plan is to eliminate the 2 ways and replace them with a better imaging pair of something that will not require digital filtration but will only see the digital crossover. The crossover can be at a low enough frequency, perhaps 100Hz, so there will be no significant time alignment issues caused by the digital circuitry.
Another option would be to bi-amp a single pair and replace both speaker pairs. This is hard to justify since the T-Ls are pretty effective. In fact I’ve needed to roll them off at 25Hz. They use a pair of the old Focal kevlar cone drivers (8".)
Maybe some time-aligned D’Appolito configuration?

Fair enough. The larger Maggies do need a good size room, and even front wall for the dipole radiation. When you mentioned you bi-amp, I thought you (may) have enough power to drive them properly, hence the mention. I haven’t heard Vandersteen speakers, so I couldn’t comment on their sound. Though the consensus is they are good value speakers at their price point. Fyi PS Audio are working on some new hybrid speakers, including a 2nd top range model <$10k which will have active sub & mid-bass drivers and an array of planar magnetic drivers. Paul M has been talking them up, so they should be good. With the active bass drivers, they should be relatively easy to drive also. Here is video Paul posted fyi - https://www.youtube.com/watch?v=xa8nqlLs3wQ |
@joey_v I generally agree with you, though Arnie and Paul already did a lot of work on PS Audio’s new speakers before he passed, even producing a one-off reference shown in that video. And Paul has said he will only release a new speaker when it is ready & meets all the goals Arnie and he talked about. Also, are you aware of PS Audio’s “Trade Up program”? - https://www.psaudio.com/buying-options/trade-ups/ That said, I’ve got no bone in this. There are a lot of good speakers under $10k, incl: Magico A3’s. However I mentioned the PS speakers as they may better meet the OP’s requirements. |
@joey_v I respect you as an audiophile, so I take your point. On a personal level I think McGowan is a tool. I (used) to be FB friends with him until he took serious offence to a humorous photo I posted of a guy chomping a giant Denny’s burger. Seems Mr McGowan is a rather sensitive Vegetarian. I actually later sent him a new friend request & apologized for causing him any offence, but he was apparently inconsolable and deleted my request. That said, with Arnie having produced a full working reference speaker; the “IRS killer”, co-developed plans for replacement planar magnetic midrange drivers for the now out of production Böhlender-Graebener panels, and with all their history at Genesis Advanced Technologies, McGowan would have to be a complete jackass to screw up Arnie’s legacy. |
@tomic601 Infinity Systems certainly changed direction in terms of their speaker designs following Arnie Nudell’s departure in 1989, no longer producing boxless dipole speakers. The rights to the EMI drivers were also split between Harmon and Arnie, with Arnie keeping the Emit-R tweeter which formed the basis of Genesis Advanced Technologies’ tweeter. From there, Harmon tightened the screws leading to the departure of Company President Cary Christie in 1995, who continued on only as a consulting designer for another 3 years. A factory fire then destroyed much of the tooling for the remaining EMI drivers, hastening the end of the era of classic Infiniity speakers. Harmon were only really interested in milking Infinity to develop it’s own line of speakers. There used to be a photo on the internet of Harmon/Revel voicing a pair of Revel Ultima Gem’s with Infinity IRS-Omega speakers, but that photo mysteriously disappeared after I mentioned it in an Infinity thread a few years ago. So it was really Harmon who screwed up Arnie’s legacy, hastened by bad luck. |
