Looking for amp advice (punk, rock & reggae edition)


My current amp isn’t doing it for me. Marantz pm6005 which is class D @45 wpc. Speakers are Focal Chorus 807V. It’s very detailed but a little clinical, my biggest gripe is a lack of midbass. According to Stereophile the impedance curve dives to 4 ohm between 100 and 200 hz which is where I think I the problem lies. All indications are that more power is needed to corrrct this which seems plausible as the more volume I give it the more it fills in in that range. The problem is that apartment living doesn’t allow 100db listening sessions.

So, I’m looking for an amplifier (separates or integrated) that has the current needed to round out the sound. The speakers are staying for many more years so replacing them isn’t a viable option, plus I love the sound.

Im interested in going tube but I have no experience with tubes. I have so many questions regarding tubes it could probably be it’s own thread but it seems to me that people love these more than SS on the whole. I’m open to any suggestions though.

My budget is $2500 (used ok but prefer new)

I listen to punk, post punk, lots of reggae (specifically dub), some electronic, a little jazz and some jangle pop (think REM).

Im looking for a warm side of neutral sound with good detail that can keep its composure with fast music yet be gentle enough for jazz. I like bass, if there’s an 808 or that dubby bass guitar, I want to hear it. These speakers do a nice job when the signal is right.

My analog front end is a PDC with a 2M Blue through a Lounge LCR MKIII. All interconnects are AQ Evergreen.

Thanks

gochurchgo,

I have a pair of Nuforce Ref 9 V3 SE mono amps that now have the awesome TDSS Level 3 upgrades in it. Paid $1400 for the pair originally used and the Level 3 is out of your budget. But Bob Smith at TDSS does offer a Level 1 upgrade for $1000 for the pair that improves the sound of the already very fine Ref 9’s to a new level. Read the testimonials about the TDSS mods. 100% of the owners have raved about the improved sound. The Ref 9’s already have great drive in the bass with a touch of the sound of tubes in the mids. The highs have great detail without ever becoming harsh. The TDSS mods make them even greater. I’ve heard my Level 3 upgrades in 5 different systems with speakers such as VMPS RM40’s, Sonus Faber Futuras, a Bill Dion suped up pair of Tekton Double Impacts, and 2 different speakers that Bob Smith at TDSS made that are very dynamic and detailed. In all these different speakers and systems, the Ref 9’s with TDSS upgrades were spectacular in all ways towards recreating the sound of live music, BUT...with no listener fatigue. The bass in all were incredible--deep, with great definition and power. To stop listening is the one MAJOR problem. It’s hard to do--you know, one more cut, just one more. The Ref 9’s are 175 watts /ch. prior to the mods and they increase in power depending on which upgrade you get.
So, I’m looking for an amplifier (separates or integrated) that has the current needed to round out the sound.
@gochurchgo   I'm suspecting that is not the case. The amp you have right now is able to act as a voltage source on your speakers.  The way you describe it sounds like its more of a room problem. Have you tried moving the speakers a bit? For example, if you move them closer to the wall behind them, you will get more bass reinforcement. It may also be that if you shorten your speaker cables that you will get more impact. You might also try auditioning different cables as well, as they can have an effect.

I would certainly exhaust easy and inexpensive things like this first before buying another amp! If  you're on a budget, the last thing you need is to find that you've not solved the problem with the next amp...

Also just a FWIW: electronics really don't care what sort of music you play. The idea that there is a certain amp or speaker out there that is best for a certain kind of music is a persistent myth.
The way you describe it sounds like its more of a room problem. Have you tried moving the speakers a bit?
OMG yes. Every way I can even if it was an idiotic arrangement for a living room. I did everything but glue speakers to the ceiling. The biggest difference was starting the speakers 30" from the front wall and moving backwards in 2" increments. The thing is that I have a wall 3' on the left side of the left speaker but the right wall is 22' away (dining room). I know this drastically affects things but there's no way to fix that.

Also, I had read that if you stand directly between the 2 speakers you'll hear what they are putting out and then you need to make changes to their position to get that same sound in the sitting position. The hole in my midbass is evident when standing between the speakers.

They are easy to drive but the impedance curve drops to just above 4 ohms in that frequency range. The Stereophile review was done using a 100wpc tube amplifier so I have been looking at more power to fill in the holes.
You might also try auditioning different cables as well
 If you have some insight as to what to look for in a cable I'm all ears...
