Accuphase vs Luxman

https://forum.audiogon.com/posts/2841538

Glad to meet someone from Toronto!

The C-3800 was introduced in 2010, replaced by the C-3850 in 2015, and then the C-3900 in 2020.  Accuphase is replacing the C-3900 with the C-3900S as of October 2025.  The C-2900 was introduced more recently - I think around 2022ish?

Accuphase makes incremental improvements to its products and releases a new model every 5 or 6 years.  Accuphase is a small company of fewer than 100 employees that only makes 5-6000 components annually - all assembled by hand with strict quality control and obsessive attention to detail.  They have 26 engineers on staff working on R&D (and I imagine quality control) etc.

Accuphase makes incredible power supplies - I have a PS-530 and a PS-1250 for my amps.  They clean up the crappy power with high distortion in may old downtown neighbourhood and regenerate perfect AC with very little THD.  A PS-550 would work well in your system.  When I had an A-48 amp I had it plugged into the PS-530 and it made a huge difference.

So, pre-amp and power supplies are areas to explore for potential improvements to your system, and Accuphase offers some good options.

As far treating room, checkout Q7D Diffusor for your bare walls and first reflections,

@lalitk I actually saw this site Gika Acoustics that you mentioned late last night actually.  I'm not sure if they ship to Ontario Canada.

But I stumbled across this local company closer to home.  It's in Ajax Ontario about 45 minutes north of Toronto.  This lady makes these incredible wood diffusers! All custom and very unique!

@toronto416  I'm definitely going to look into these Accuphase power supplies. Also, seeing that you have incredible experience with Accuphase,  is it better to upgrade the preamplifier or the processor- from the C2300 to the C2900 or from the DC-37 to the DC-1000?

@fire_water, no reaction to my suggestion to look at changes other than electronics to scratch your itch.

While I second the idea for some room acoustic upgrades, my initial impression was that you're pleased with the esthetics of your room so may not want to change much there.  So hopefully you can find some changes without diminishing the visual and physical comfort of your room.

Regarding speakers, here is an explanation of the improvements from your AL5s to the current AL6.  Yes he's a salesman, but I think he does a reasonable job here identifying the upgrades.  If interested there are other reviews of the newer version as well.  https://www.youtube.com/watch?v=E87NIzNgGAA

I'm not pushing Klipsch, there may be other speakers which could make a greater improvement than an electronics change.

Good luck.
