Amp Preamp Advice


I am fairly new to the forum and perhaps someone has already had this discussion. If so, please forgive me.

I currently have a Parasound Halo A23 amp, Parasound New Classic 2100 preamp, Marantz 8006 CD player which can also be used for streaming, and Focal Aria 926 speakers. Overall, the system sounds pretty good. But are we ever really completely satisfied with the sound? I have been considering various options to improve the sound quality-more depth and clarity, bigger soundstage, etc. and wanted to see if I could get some advice before I make another purchase. Here are some of the options that I have considered:

1) Upgrade to a Parasound A21 amp which will increase the watts from 125 to 250 and the amperage from 45 to 60. If I go with this option, I will eventually upgrade the preamp, probably to a Parasound P6.
2) Upgrade the preamp to either a Parasound P6 when some are back in stock or to a Musical Fidelity or NAD C165BEE now. I would keep my current amp at least for now.
3) Gift my current amp and preamp to my son to start his first "real" stereo system and purchase an integrated amp which would replace both my amp and preamp at the same time. I know that there is a whole conversation to be had about which are better separates or integrated. But the integrated amps that I am considering are the Parasound Hint 6, the Musical Fidelity M5si and the Musical Fidelity M6si. In a way, I feel that the first two might be lateral moves from where I currently am although they would increase my wattage slightly and probably give me a better DAC than I currently have. The last one is probably more than I wanted to pay for an integrated at the moment, but I might could swing down the road.

What do the people say who probably know infinitely more about building a good sound system than I do? Or should I go with my last option and just be content with what I have? Thank you for your responses.

I have had a Parasound 23 for a few years. It was just OK but I had a crappy room so I did not care. I am getting a used A21+ today. It is for my headphones in the long run but I will listen for a week on my hard to drive Thiel CS3.7 speakers.

This amp is going to be pairedwith a CODA 07x preamp but is in for repairs so I will be using a Topping pre90 preamp to test it this week. Hopefully they are compatible. The Topping is a bit difficult to pair with amps.

I can post my impression of the A21+ next week.

The following is an incredible integrated. It is being compared to $13450 Boulder 866 and some D’gastino integrated for $40K (on Stereophile). I also own this unit and it is exceptional.

Just got the A21+.

Nice amps (John Curl design) both the Halo A23 and the A21 they only need 1v in!! for them to give their max wattage output. And most sources today give more than 2v output some even 4v and 6v!!!
So you need a preamp with next to NO gain, or go direct from the source if it has a volume control.

For preamps that have low gain look at the Schiit FreyaS with remote control!! and balanced, at $599 it gives you the choice of being used as passive, active tube or active solid state.

Even cold and traveling though the current Bomb Cyclone from Oregon to California the A21+ is so much better than the A23. More bass, way more clarity, not so veiled on top as the A23. This unit is still cold too.

The $599 Topping pre90 works great with the adjustable gain on the A21+. For, the $3K I paid in total for the A21+ and Topping pre90 this is heck of a good sound.

I have had 2 amps work with the Topping pre90, the Parasound A21+ and Benchmark AHB2. Both have adjustable gain.

I also had 2 amps that were awful with the Topping pre90. The CODA #8 and the LSA Voyager 350 GAN. The amps sounded way too loud.

If you can make the Topping pre90 work with your amp then it is a screaming bargain. It has similar character as the incredible Benchmark LA4/HPA4 preamps.
Must of us with great systems got there over decades by upgrading one component at a time… reaching each time to get a significant upgrade. I always go at least 2x in investment on a new component.. 3x is nice if you can manage it. I always try and trade in.

I see two obvious courses… preamp or speakers. If you are happy with the overall sound of the Focal, then think of the 948’s. This will get you a big upgrade. If they are just fine, then do some auditioning. Open minded listening until something really grabs you.

The preamp is also a big opportunity. Here I would really recommend going used… so you can get into the $6K range. If you want more musical, then go tubed preamp. Be careful on detailed versus musical. It can be seductive to go for components like Benchmark that are very detailed, but can rob you of the emotional connection.

To get a firm direction. Find a couple of dealers and listen to a few systems way beyond your means… what appeals to you. Pay attention to the emotional connection. If you can get a firm idea of where you want to go. Then the dealer, professional reviews, and advice can get you there over time.
If you stick with the current amp/preamp or not, a powered subwoofer or two with the 926's would be beneficial in helping you reach that depth and clarity you are looking for.
