Hi Guys,

Ears--I misspoke--I did not mean to say that you and Dmason & TheChairGuy thought the receiver sounded badly--just that out of the box it did not sound quite right or up to snuff just yet  

TheChairGuy--you're absolutely right that I will need to break it in--I just wanted to give some impressions regarding how it sounds right out of the box. I will definitely reserve final judgement until this baby burns in for a good 2 weeks--but so far I'm pleasantly suprised for $179.

Am I the ONLY one of us that finds that blue/pink glow coming out the front as being hideous?  

"It just sounds tubey"

Didn't bother me at all...but, now that you mention it....

TheChairGuy-

To tell you the truth, I wasn't even planning on trying the Dakiom's with this amp. They do a great job with my Cayin tube amp, and that's probably where they'll stay, especially given that the JVC is a class D amp. My Cayin is going to stay in the basement with my 2-channel system, and the JVC will go in the living room where I'm building a small home theater. I'll definitely swap out the Cayin for it for a little while to see how it sounds, but I really don't see it staying there even though I'd love it if the thing was good enough to let me sell the Cayin and consolidate both systems.

My f-10 has a button on the remote to turn the blarring blue down or off.
I will bet these two receivers are exactly or close to the same other than features.

Mf-10 has opened up after 45-50 hours of use and the soundstage has grown as well as that tubey sound

For ht use, I am pretty sure that this receiver will not cut it as it shut off whith LOTR playing last night whith the volume at 30 while in dd ex mode.

But for two channel, this could be a Pany alternative whith a tubey sound that is better than the H/K 2005 already.

I imagine this receiver could be used to bi amp whith also via one of the modes such as all channel stereo ect.

[TheChairGuy]

Yep, the ES1 has that same dimmer function, it's under the 'secret' door.

Glad it's sounding good to you, Ears, at no point in the first 225 hours did it ever sound awful...just more or less good sometimes.  It's a helluva' value any way you cut it.

I really should listen to it now that it has been cooking for 2 weeks to see if there have been more changes...but I am on the road traveling.  I am just outputting the FM signal from JVC to the new Exodus digi-amp and keeping both cooking for a few days.

I don't like 24/7 CDP playing, someone once told me that's a easy way to burn your CDP up.  Don't know if true, but it sounded prudent to me...spinning mechanical device and all for days on end.

[Dmason]

I couldn't resist a little cosmetic surgery on the now four days cooked F10. Here is what I did:

--replaced the captive PC with a good Belden one, soldered directly to the receptacles. Installed a few Rat Shack EMI chokes on the cord, and a good Marinco plug.

--placed it on Aurios bearings, put ten pounds of audiophool approved sand in three Ziplok baggies on top.

The overall presentation took an immediate leap forward. Gone is any stridency in the upper registers, midrange resolution and palpability vastly improved. I found the dimmer switch and got rid of the ghastly blue-ness. That is also an improvement.

It should be noted that I am using a medical grade power re-generator 25X the cost of the JVC and have no idea what effect this lends with optimal power sourcing, but I have learned that upgrade PC and lots of attention to insulation/isolation is de rigeur with ALL "digital" amp types I have encountered. A Bybee on the IC might be a good bet also.

TheChairGuy and I are hearing similar things thru the outstanding Vandy 1C, namely that this cost-effective pairing sounds pretty damn sweet.  

FWIW, I prefer this outfit's overall sound to the Panny 45 already, which is no slouch either. This is a good alternative for the people who find the TI sound not to their liking. I don't know if it could replace a good EL34 set up like the Cayin. Too different.

It may do just that for me... and I had no intentions of the sort when I ordered it. I just unpacked mine and plugged it in... man, does this thing ever sound good. And that's right out of the box with badly oxidized bare copper wire for speaker cable. The next few days should definitely be fun.

Tried the f-10 whith sacd and it is better than the Pany in that respect but not even close to my Sim i-5.

When I mentioned hearing the receiver open up, I forgot to mention that when I could get none of my speaker cables to fit, I went to Home Depot and bought some of that HD 14 extention chord that has been raved about, and this could also be part of what I am hearing break in.

Dmason, although I agree that some may like the tubey sound over the precise sound that the Panys offer, it has nothing to do whith speakers as I am using some of the best drivers in the world...bar none.
All Scan Speak whith revelators all around except the rear center which is a not even close B&W LCR speaker.
I am also using a highly modified Philips 963sa for a source and it has already retired a Denon 5900 and a Sony 9000 whith Modwright signature mods.

I still prefer the precise extremely detailed upper mids/highs, and wider soundstage of the Pany, but I do dig the tubey mids and bass of the JVC.

I am using a large Powervar conditioner on all the digital recievers I have tried, except the H/K dpr 2005.

[Dmason]

Sorry for your misunderstanding; I was only suggesting that TheChairGuy and I were "hearing the same thing." ie: hearing the same speakers (1C) providing a somewhat identical sonic. I would never dream nor feign objectivity or anything of a conclusive nature when we ALL hear decidedly different things, through different ears, and hearing is non-linear. I am always interested as much in the variance in the human hearing experience.

Beyond that, I am hardly a hair-splitting audiophile, but a musician with a good sense of what actual instruments sound like. BTW, interestingly, the fellow I sold my Panny 45 to has compared and prefers the different presentation of the 45. I believe the Tripath approach does not excite my tinnitus, an inconvenience the result of playing in loud and fun rock bands for years before I had to get a real job.

I have noticed that the tuner is quite sensitive and very very musical sounding as well A total bonus.

[Ears]

Dmason, no reason to be sorry as we hear what we hear.

And I beleive were all hearing similar, and good things.



A mixture of the Pannys precise revealing highs and upper mids combined whith the JVC'S bass and tubey sound would be fantastic imo.

I am mainly trying every digital receiver I can get my hands on to have one modified anyway for H/T use... and maybe 2 channel also.

I am interested in everyones take on the JVC, whether they have Paradigm monitors, Theil 7.2's. or even better speakers is all I meant, sorry if I mis-read your post.

And I am not an audiophile.....well maybe an audiophool, and since I bought a dlp projector, maybe a videophool also.  

[AphileEarlyAdopter]

Dmason/Ears,
Are you using analog or digital input into the JVC ?
Dmason, did you see any Tripath chipsets inside the JVC ?

[Dmason]

I am using analogue only.

This is a hybrid analogue amp: the output devices are analogue. It has a good sized power supply, and ALOT going on in this little box. I did not see specifically Tripath chips, but did see the lowpass filters typically found adjacent to these and other hybrid architectures. It could well be such though, based on the sonics, and could also be something to do with Tripath new "Godzilla" architecture, purported to be a more efficient, more elegant design. Who knows. My gut tells me however that this is JVC's own baby, and I like their take on things.

I could see where there might be some room to work, but it is tightly packed, a testament to the design team from the Sharp minded MotherShip. Current caps would be high on my wish list if they could fit, better output wiring, real speaker taps and input RCAs, ...just replacing the PC made a very tasty improvement.

Tonight the separation in congested orchestral work is apparently improving. I have been sampling high quality big budget soundtrack type stuff to allow it to do its widdow best, with the below mentioned, sounds really nice. Very musical.

[gary]

Does that mean that you're using the DVD input and running in Direct mode? I had been using DVD input, and I thought things were going pretty well. CD's were sounding great, but for some reason my turntable just didn't sound the same. With the Cayin, I preferred vinyl to CD, no question - even though I have a $1500 analog front end (Clearaudio Emotion & Bottlehead Seduction pre) and a digital front end that cost much more (Philips 963sa, PT P1-A w/ SOCS, PT P3-A Modwright II). With the JVC, the opposite was true and by a large margin.

Then, just before heading to bed I was going to put the receiver on FM and let it run over night and I happened to hit the Direct button. Didn't have time for critical listening, but I could have sworn the CD I was listening to sounded much better. And since then I've been wondering if in regular mode the analog signal gets converted to digital and processed through the DSP whereas in Direct mode it goes straight to the amp. If that's true, it might explain why my turntable sounded less than impressive. Unfortunately the manual wasn't much help, guess I'll have to wait until tomorrow when I can do some more listening. Any thoughts?

[Ears]

I have tried both the digital coaxial and analog ins and my modified 963sa, sounds more detailed from top to bottom and the soundstage is deeper and slightly wider using the analog in.
I used the digital in for HT sonics, but may try it whith analog for grins.....or better yet, maybe better HT sonics.

I have also heard the fairly loud fan, kick on in this thing more than once.

I can't even stand listening to the Panys analog section, so the F-10 is definitly superior sounding in this regard.

[TheChairGuy]

Dr. DMason,

Congrats on the successful operation!  As I mentioned, I haven't spread the patients rib cage open yet....is it THAT tight in there?  No room for a large pacemaker in there?  I am so glad the power cord 'stent' opened the congested arteries up so well  

Ears, you must play louder than I (or have less efficient speakers than the Vandy 1c) 'cause I didn't even know this little sucka' had a fan.  Back to some of yesterday's comments, I may not have caught some of the high distortion folks heard as I don't think I turned the juice up on the JVC past about 25 or so.   It's plenty loud, in my room, at this level.

The fan was running after, and possibly during a flick whith dts-es sound running 6 speakers in the large mode that are all 6ohm 88 db except for my B&W rear center which is 8ohm but can dip to 3 ohm.

The JVC was being run at 28 at the time.

It is plenty loud for music but it did shut down once during a dynamic peak while watching a movie at 30.

Thanks Doc and Ears,
It looks like the JVC is a hybrid, operating with an analog waveform input, but possibly, amplifying using some digital/pulse techniques.
My current interest is in mainly digital input amplifiers. This is to avoid the requirement of a high end CD playback.
The JVC could be a good alternative people with a good CD playback equipment.  I will probably try it, but most likely will try the XR70 first. The expected September data for it, is not so far away, especially when I have the XR50 to play with currently.

I don't know about the slightly cheaper cousin, but the RX F-10 says digital hybrid right on the front of the receiver.

I have tried a 25,45,HK DPR2005 and the rx-10 so far whith a Kenwood 7100 on order that also uses the TI solution.

I am fairly certain the H/K, and all other current digital receivers besides the Panys And Kenwood are hybrids.

The Sony es models may also be a digital direct.

[ABEX]

Gee I missed this whole adventure!

Will be interesting to read what the final findings are!

[TheChairGuy]

Oh, ABEX, you got a whole lotta' reading to do bro....

This is the adventure that NEVER ends.
