Help with possible integrated amp change for better match with my speakers.


Hello,

I've been using a Simaudio Moon 600i V1 to power my Focal L&R Utopia B speakers for some years now. 

I have spent lots of time with power cord, and interconnect cable changes. Also different outlets (Furutech GTX-D, both NCF(R) and Gold) I've plugged the speaker ports for a less bloated sound and have the system sounding actually quite nice. BUT...... all the same I'm missing some of the fine micro details buried in the music.  

This brings me to my question to you. I've been thinking about trying eather the Luxman L-509X or the L-595ASE integrated amps. Do you think this would give me better detail retrevial than my current 600i amp does? Would the 595ASE class A amp do a better job with my speakers than the 509X?

Or is there a better choice of integrated amp than this I should consider to achieve my goal for better resolution of fine micro details? 

Thanks for your time and thoughts.

The 700i has crossed my mind, although I question how much an improvement vs a more lateral move it would really be. 

I'm using an oppo 205-disc player for all my silver disc playback. I also have a Fanfare FM tuner, and Lyra Lydian Beta cartridge/Ortofon TA-110 tonearm on Merrill Williams 101 table. That into the whest three signature phono stage.

I have different speaker cables on the way here, so will find out soon if that could be a positive influence. 

to paraphrase a saying, there are details you know you are missing and there are details you don't know you are. At your very high fidelity level, if you don't hear a detail, it may be by design. I can only imagine very minute details to not be there. 

A.I. is extremely intriguing. At least to me. The available information will only grow over time.

Don’t be afraid to call B.S. I have found the algorithm to not always be correct. 

 

The Focal Utopia Be (Beryllium) speakers—such as the Utopia Micro Be, Alto Be, or Scala Utopia—are high-resolution, revealing speakers with low distortion and excellent dynamics. They’re known to be both demanding and revealing of the electronics upstream. Matching them with the right integrated amplifier is crucial for getting the most out of them without sounding clinical or fatiguing.

 

 

Ideal Traits for an Integrated Amp Match:

 

 

  • High current delivery: They benefit from amplifiers with good grip and current, especially with the beryllium tweeter and sometimes complex impedance curves.
  • Neutral to slightly warm voicing: To balance the resolution and potential brightness of the tweeter.
  • High resolution and low noise floor: These speakers will expose any harshness or grain.

 

 

 

 

 

Recommended Integrated Amp Matches:

 

 

 

1.

Vitus Audio RI-101 MkII

 

 

  • Why: Gorgeous class AB sound with a touch of warmth, fantastic resolution, and current delivery.
  • Sound Signature: Smooth, authoritative, and rich.
  • Cons: Large and expensive.

 

 

 

2.

Luxman L-590AXII or L-509X

 

 

  • Why: Delivers refined, holographic sound with excellent tonal richness and control.
  • Class A (590AXII) or AB (509X).
  • Sound Signature: Smooth, dynamic, slightly warm.
  • Cons: May run warm; not cheap.

 

 

 

3.

Gryphon Diablo 120 or Diablo 300

 

 

  • Why: Extremely high-current and neutral with deep control and massive headroom.
  • Sound Signature: Precise, bold, ultra-dynamic.
  • Cons: Price and physical size.

 

 

 

4.

Pass Labs INT-60 or INT-250

 

 

  • Why: Pure class A (INT-60) or high-powered AB (INT-250), known for musicality and grip.
  • Sound Signature: Rich, engaging, powerful.
  • Cons: Heavy and power-hungry.

 

 

 

5.

Hegel H390 or H600

 

 

  • Why: Very high damping factor and control, smooth top end, great synergy with Focal tweeters.
  • Sound Signature: Transparent, neutral-smooth, slightly dry.
  • Cons: Less romantic than others.

 

 

 

6.

Aesthetix Mimas (hybrid)

 

 

  • Why: Tube/solid-state hybrid that brings texture and warmth without sacrificing control.
  • Sound Signature: Lush midrange with good bass authority.
  • Cons: Less known but excellent synergy.

Thank You for the follow up. Cables and Cord will have a positive influence to be sure.  Careful system matching is key.  Nice gear overall. I would consider a Simaudio Moon CDP to mate with the Integrated Amp.

 

Happy Listening!
