Improvement over 2002 Denon AVR-3802 for 2 Channel Music System


I currently have a 2002 Denon AVR-3802 that I am using for a dedicated 2 channel audio system.  My room is a converted garage bay, about 15'x24' (with a bunch of guitars and amps and such in it - multi purpose room...)  I have Revel Performa3 M106 stand mounted speakers, and an SVS 3000 Micro sub.  I am streaming using Roon (Qobuz and Tidal as well as DSD "rips" of my SACD collection) into a Ropieee loaded Raspberry Pi 4 into a Geshelli Labs JNOG2 (with AK4493).  I have a Sony BDPS-5100 for playing CDs via coaxial out into the Geshelli (also used for ripping SACDs).  For vinyl. I am using a late '70s JVC QL-A7 with an AT VM540ML cartridge into a Schiit Mani2 pre.

Anyway, overall the sound is really good.  However, I am being tempted by the idea of separates, and what I can do to best improve my experience.  I am thinking middle-of-the-road for now.  No Mark Levinson or Mac (yet).  Candidates include the Parasound P6 pre with either the A21+ or the A23+ power amp, or maybe the Anthem MCA 255 Gen 2 (not going to go all the way to the Anthem STR).  Another extremely interesting idea is the Benchmark AHB2.  For budgetary purposes, I would likely buy an amp first, and continue to use the Denon as a pre for the time being.  I use it in Direct mode, WITH bass management (speakers set to small - sub set to on). Eventually, I would want a pre with Bass Management as well.  Not super interested in a pre with a built-in DAC, but most seem to have this (Including the P6).  After that, a better phono stage...

My quandary is, what will I really gain here with a new amp?  The amp section of the Denon is solid- does not seem to be lacking much other than lower volume push / punch / control and (of course) definition at more extreme SPLs.  I feel like the A21+ would be a significant improvement, but not sure I want to drop $3k on an amp when the current situation is pretty good. 

I guess I am wondering if a lower wattage (closer to that of the Denon's 105 WPC), lower $ amp (like the A23+ for example) will get me any significant (audible) benefits over what I have, or do I need to bite the bullet and go with the A21+ or Anthem.  I know that eventually the Denon will give up the ghost, but I bought it brand new in 2002 and it has never failed me yet.  I just want to get ahead of its inevitable demise.  I know it seems like I am answering my own questions here, but I think I need some affirmation from like-minded folks. 

I'd hate to drop a few grand and be nonplussed with the results.  Not a unique situation, I know. 

Talk me into it.

I wouldn’t spend a penny on gear until you acoustically treat your listening room and get the target listening curve you like. As for separates I would get a good pre/dac combo that bundles room correction software first, new cables second, and a new amp last. You may like the improvement from a treated room with a new pre/dac and cables you don’t need a new amp.

Thanks.  Some great advice - totally get that!  This room is, however - if not "untreatable" it is at the very least "difficult to treat" in its current form.  For me.  I have done what I can , but there are so many things getting in the way of that.  Below is a pic of when I was taking measurements with an old Spectrum analyzer.  It is from directly behind where I put my chair to listen, when the room is in that "mode":  It is a combination practice room, YouTube Studio, and listening room.  I am only afforded this one space for all these endeavors.  It is really tight, and houses a bunch of stuff.  Even more junk is behind the camera...

You can see the Revels to the left and right of the guitar amps.  The PA speakers are going to be taken out, so there is probably opportunity for corner bass traps or some other treatment there, but that is the backdrop for my YouTube channel, so not sure what to do, exactly.  Believe it or not, the sound is pretty good in the listening position, and I have EQ'd the sub to the extent I can using the analyzer and the SVS app.  I know it will never be acoustically perfect 
(or even close).

even in an untreated room the difference will be audibile a mass produced avr like your dennoni s built as cheaply as possible so rhr preamp stage and amp are not great

 

so upgrading to a better integrated will give you a

far better sound 

we have a perfect amp for you

Thanks!  More interested in separates.  I am looking for "old school" - Class AB amp - separate pre / power / phono / DAC.  Not really looking for anything with "big tech" like room correction etc. I want to keep it simple and with the least amount of stuff that requires software updates in the core components.  I work in IT and want to leave the complexity there  - not in my audio chain., if that makes any sense.

Wow, you sound like me about 3 years ago. I had a highly rated Denon AVR which I switched from using as surround-sound, which sounded fine, to use as a two channel. It was awful. I had several very good two channel systems in the past, and the Denon was the pits. I saved up and went with a Luxman integrated. They have lots of choices. There are many other great integrated amps, but for me the Luxman had all the right features and sound. And I wanted great sound but didn’t want to get into total separates or tubes. Amazing difference, just lovely.

Many new integrated amps have built in DACs now, I would suggest to go with separates for a DAC, they really do sound very different.

Hope this helps. By the way, I've been in IT since 1993, just retired. So I know what you mean. 

 

My quandary is, what will I really gain here with a new amp?

That’ll get you halfway there, but as long as the Denon’s preamp section is in the signal chain it’ll be a significant bottleneck to much better sound.  Not sure why you’re against an integrated as they can be a great value vs. separates, and for $3k you could get a very nice integrated and just be done rather than then having to search out a preamp that synergizes well with an amp.  Just a thought, and best of luck. 

Black Ice Audio has a product that is designed for rooms like yours that can't be treated in the conventional way. I would start by checking out their preamp:

 

Thanks, to all.  The Black Ice stuff looks nice.  I am not big on processing the signal though.  I can only think of aural enhancers like the 'ol BBE Sonic Maximizer...  Not my bag. I realize that this is an antiquated example, but every time I have heard something that purports to fix audio issues using an algorithm or some sort of processing, I am skeptical.  

My Denon, being a 2002 has a MUCH better power section than the AV receivers of today (IMHO).  Anecdotally, I know this as I replaced the 3802 with a 2018 AVR-3500h in my Home Theater system.  The 3500 is ok, but does not have the "authority" that the 3802 had.  Especially with 2 channel content.  TI do know that maybe a more fair comparison would be a 6500 series or something.  But the 3500 was at a similar relative price point to what I paid for the 3802.  That said, the 3802 is getting old.  Also, to many of your points, the Pre in it was never "audiophile grade", but built mostly for AV use.  Totally get that I need to replace it.

To answer some of the above questions, I like separates for serviceability and signal isolation.  I like the idea of "older school" design in most of the components as I do NOT want to be upgrading an entire integrated amp each time technology changes.  I'd much rather have an outboard DAC and Streamer that I can swap out at much less expense and keep the pre and power sections.  Another reason - Budget / Cashflow.  I can better rationalize getting a Power Amp for $2-3k now, a pre for $ 2k 6 months or a year down the road, and then a better phono stage for $1-2k in 18 or 24 months, rather than spending $6-7k all at once.  Replacing my existing components bit-by-bit.  Just a process that makes sense to me.

for years i had a denon 4802 (one model up from the 3802) and it had a damn good amp section--i passed it on to a true audiophile buddy who was also surprised by how good it sounded. however, your revels need a lot of high-current power and i would go for a parasound amp (coincidentally, i power my revel performa f30s with a parasound hca150 and it's a significant improvement from the denon).

Thanks. I forgot to mention another amp I am looking at is the Outlaw 2220 Monoblock (pair). Or maybe the Emotiva XPA-2 or the monoblocks (XPA HC-1).  Too many choices...
