I have been a very happy Luxman EQ 500 owner for about the past eight months and it matches very well with my Kiseki P.H. NS. The Luxman sounds wonderful, especially with NOS tubes!
The Hana cart has an internal impedance of 6 ohms. The EQ 500 has two impedance levels of MC: high 40Ω, MC: low 2.5Ω, so 2.5 ohms may be a bit low and the 40 ohms too high. I would therefore recommend contacting Luxman USA and ask them about the Hana cart matching their phono stage.
You are welcome lcarpediem. I should add that some people think impedance matching may be over rated. I had that experience myself when I owned a Herron VTPH 2A phono stage. I frankly had a difficult time hearing much of a difference when using different loading plugs. I also ran it "wide open" @47k and it sounded quite good. I think Keith even recommended that setting for most MC carts.
However, loading may be more critical when using SUTs, which the EQ 500 has, hence my recommendation to contact Luxman.
Thank you very much grk,
I will do. And try to find the contact of them in Europe.
What are the possible consequences, sonically, of this possible incompatibility?
According to you, this possible lack of 100% compatibility may be inconvenient enough?
Will the versatility of adjustments on the EQ-500 not be enough to overcome this possible inadequacy?
Please see this short excerpt I took from the measurements of the Luxman EQ-500, from Stereophile magazine:
"but these measured gains were affected by the interaction of the EQ-500's input impedance of 56 ohms (High) and 7 ohms (Low) with the Audio Precision's output impedance of 20 ohms..."
You can see it in here:
It gives the feeling that, in the measurements made by them, the lag is not that big (7 ohms Low) for the values of the cell (6 ohms), right? Or am I seeing this wrong?
Sorry for the bodder and many thanks for the help
"What are the possible consequences, sonically, of this possible incompatibility?"
"The audible effects of using an overly high load impedance setting can typically be a lack of low frequencies, a slightly hard or ”unmusical” sound with poor imaging. If the sound quality is somewhat veiled and lifeless, the impedance loading may be too low." https://www.mysonic.space/phono-cartridge-impedance-loading
I don't think the Stereophile measurements address the issue of whether or not the Hana is a good match.
You should also check with Luxman dealers as to what cartridges they think are a good match.
grk, that opinion article you mentioned above (very well written by the way), does not apply at all to the possible differences between the impedances of the phono EQ-500 and the Hana Umami cartridge.
These differences (as I was almost sure) are entirely irrelevant and do not apply to the one mentioned by the opinion article author.
I had already informed myself from knowledgeable people in the field that there would be no problem at all, which was confirmed by Luxman themselves.
"The HANA-Umami quoted output of 0.4mV will be accommodated by the Luxman EQ-500 “low” MC input (0.18mV minimum sensitivity) required to drive EQ-500 to full output while preserving S/N ratio.
HANA-Umami’s quoted internal impedance of 6 Ohms would be best partnered via the EQ-500’s “low” input impedance. (i.e. 2.5 Ohms)
In this case, the 6 Ohm matching of HANA-Umami coil output impedance to “low” EQ-500 input impedance is within acceptable operational parameters.
While the HANA-Umami’s published specs calls for “recommended loading” of > 60 Ohms, this would not always apply. The 60+ Ohm recommendation would likely refer to “semiconductor/ fixed resistor based phono loading”. Along with its unique vacuum tube based circuitry, the EQ-500 features independent L+R channel “transformer based loading”, having unique electrical behaviors. The Luxman EQ-500 (internal) transformers can present ideal loading when they are at OR near the MC cartridge’s actual internal coil(s) impedance. In this case, 2.5 Ohms and 6 Ohms are very close and compatible.
The employed tonearm cabling and connectors will also provide slight/ additional series Ohms loading. (before signals reach the EQ-500 input, making the Ohms match even closer.) The various other front panel settings (Capacity, Impedance, etc.) on the EQ-500 are for use with Moving Magnet, Moving Iron, or Induced Magnet phono cartridge types. These do not factor into Moving Coil cartridge performance.
While many things can be written on the Internet, what is provided to you here are direct comments/answers from the Luxman engineering staff in Japan."
Thanks any way.
Well if i was to drop 4 grand on a umami red i would want to hear it with every possible ohm load from 60 to 100. Proper ohm load will get the best out of any given Moving coil since it goes to synergy of associated phono cables. I have been reading many reviews and that cartridge is dialed in @ 2 grams, not 2.1 or 1.9. Order a Mint LP protractor for your arm and table, the umami when aligned dead nuts on is a killer cartridge. I just ordered one for my Phantom 2 / Oracle Delphi Mark Vl with 2nd generation mods.
Protrator for cartridge alignment supplied with every Reed tonearm, more than enough to adjust any cartridge on Reed. This is excellent tonearm, I have 3p "12 inch cocobolo.
I’m pretty sure you can find many cartridges at $4k or cheaper, I believe Hana is your choice not because some reviewer claimed this is the best.
You can look for top LOMC models from Shelter, Dynavector, Audio-Technica, Phasemation ...
At 5k you should look for AT ART-1000 because this is unique design.
The Link may need to be translated.
The information can be trusted as this reviewer has much experience with High End Vinyl Replay Devices.
I've got an EQ-500 too, and am also saving for the Unami Red. My deck is a Luxman PD-171 with a Jelco 850 arm. Currently it's paired with an Ortofon Cadenza Black and it has really been a thrilling combination. I was happy with it UNTIL I installed a Hana MH on my secondary 'table. I must say, the hype regarding the Hana carts really seems justified. I've been really enjoying the detailed, accurate, dynamic and musical Hana. Now I just have to have an Unami Red. So now I have to cull what I can of my stereo gear and put it up for sale....
So I'm sold on the Hana without ever hearing one, but I can really recommend the EQ-500. I've had several phono stages before, including a Parasound JC3+. The Parasound was touted by many reviewers for its extreme quietness but I wasn't impressed. I don't think my unit was faulty, it just wasn't super quiet like many claimed. The Lux, tubes and all, is just supremely quiet. Turning up the volume ALL the way (without a record playing) on my Accuphase E-470 DOES reveal its noise. And the sound is a pleasing shhhhhhh of a brilliantly designed circuit.
I'm confident that the Lux and the Hana Unami will be a match made in heaven.
I strongly advise that the Umami Red is sought out and Auditioned.
The Name Umami is suggesting it is a Opposite to another.
The term Umami is from a Culinary Perspective about opposites in taste,
i.e, Sweet and Sour.
Have Hana produced a Cartridge that is a opposite to a Sound Signature they are feeling is the Hana Sound ?
