Audio Note Ongaku amp on Kharma Mini Exquisite speakers

Well, well, well… it is working a heckuva lot better than anticipated.

Actually, it sounds really excellent.

We are really performing two tests here:

Can the little Kharma fill our large room with sound? Yes.

Can the Ongaku integrated drive the Mini Exquisites. Yes, for the most part.

The highs and mids are extremely lovely. We have not heard the Kharmas sound like this before. The 6C33C tubes on the Lamm ML1 and ML2 amps, and even the 300B on the audio Note Kegons, just do not have the amazingly seductive quality of the 211 tube on the Ongaku. Combined with the Kharma’s natural seductive qualities, along with its very, very high resolution in these frequencies – it is just a joy to listen to.

As for the bass – the bass is present – and satisfactory. Enough to not take away from the rest of the frequencies. But seriously, bass is not why a person has these littler Kharmas nor a tube amp. So I would give it a ‘B’ for bass. An A+ for the rest.

Finally – there is some slight congestion during very loud, complex passages… this started to diminish over time, so perhaps the amps were still warming up from when we turned them off to hook them up. We’ll hear how far things have improved in a few days….

The upstream components… mostly using the Emmlabs CDSD/ DCC2 combo, with the Audio Aero Capitole stepping in for comparison purposes.

The Best the Acoustic Zen Adagios will ever sound

We had somebody come by who wanted to hear the Adagio loudspeakers in a larger room… and it was easiest to bring them upstairs…

.. and put them on the Audio Note Ongaku integrated amplifier…

… driven by the Emmlabs CDSA single-box CD / SACD player.

After we got over the initial shock of how much efficnet these speakers were than the Audio Note speakers they replaced…

They sounded pretty darn good!

We know some system builders like to put cheap amps on expensive speakers… well, this is the other side of that coin.

And in this case I think it worked better, as there weren’t any nasties… mostly just limitations on dynamics, mostly midi- and micro-dynamics, and various subtlties that we in the high part of the fi like to have along with our music.

Optimizations Ongaku

Things have been a little in flux here… which gave us a chance to listen closely to the Ongaku in several different configurations – primarily:

1. On the Rix Rax Outpost amp stand with a $2 OEM black power cord

2. On the Rix Rax with a $1600 Elrod Signature 3 power cord

3. On HRS Nibuses on an HRS M3 Isolation Base on the Rix Rax Outpost amp stand with the Elrod PCs…

And the winner is… 🙂

I wanted to try out #1 because that is what some of the diehard AN experts suggest sounds best, and we will try this again in a system cabled with just AN cables and with AN components, but….

Adding the Elrod PC:

a. Removed some of the compression. In some of the guitar notes on Sailing to Philidelphia, really simple notes by the way, with the OEM PC they sounded hardened near the top of the note envelope, like the note just ran into a wall – splat. With the Elrod there was a smooth rollover as the note went from getting louder to getting softer.

b. The Elrod revealed more harmonic content

c. The Elrod removed an ‘scratchy agreessive edge’ that the sound had had. As expected. A lot of people associate this edge with ‘immediacy’ (quickness, speed, etc.). If they don’t here it they may think something is missing. It is unfortunate that it is often the case that to get immediacy one has to accept this edge. In this case it did not seem to me to be the case, however, as I listened carefully for just this sort of tradeoff.

Interestingly, some people will sacrifice everything to get a little more immediacy, real or IMAGINED(!) (like AvantGarde owners :-)) and some will sacrifice everything to get rid of the ‘edge’ (like PS Audio, MIT, and SRA owners…. etc. etc.). The latter group significantly out-numbers the former, in my experience.

d. Finally, the Elrod brought EMOTION to the party. The music became engaging,. Enough so that it was much more difficult to listen to the sound because the music kept distracting me.

Presumably this was because some of the nuances were being lost with the cheapo power cord – or perhaps the ears were shutting down / shuttoing out nucance to protect themsleves from the ‘edge’ and ‘comrpession’ artificats.

When we added the HRS under the amp… first, what a tower, looks very Chinese ….

a. the first thing was very much improved bass response. Everything tightned up – but it was mostly the bass that now had a degree of slam that was quite … impressive.

b. the next thing I noticed was that HRS has a ‘sound’. Not sure what this sound is, but with 9 HRS bases here, and after trying them under everything (usually not in soup-to-nuts HRS setups though, but we are gaining more experience here as well), there is a quality to the sound that is recognizable. This is a sound that is hard to do better than – but it is becoming hard for me to analyze anymore – the old noggin just shuts down…. I could convince myself that this was less, the same, or more emotionally satisfying than the previous setup.

Perhaps over time it will be easier to settle this – and one should spend some time evaluating system mods like this – especially if one is subject to emotional swings on a minute by minute basis [aka doing system setups with one’s spouse :-)].
