not sure.... Mine was the best as far as I was aware when I got it... could be the cd700??

http://www.nakamichi.com/auto/cdplayers/cd_700.htm

Mine was supposed to have best sound quality, but then they brought out a single cd version which was supposed to be slightly better.

Does not have to go in a scoob!!!!

David_Wallis

If anybody fancys building their dream system then they will need to buy my head unit off me... Nakamichi MB100...

I think Ive had / got my dream system... Was Loud but had quality.. not really heard better yet... In my opinion... Rockford is probably too harsh for some..

Nakamichi MB100
Kenwood MP6090R
Phoenix Gold PLD1
Phoenix Gold EQ213ix + LPL
Rockford Fosgate Punch 200
Rockford Fosgate Punch 100
Rockford Fosgate Punch 100
Rockford Fosgate Punch 60
Rockford Fosgate XLC 12's x 2 Twin Chamber Sealed Box.
Rockford 6.5" Power Series Mids with tweeters from Audiophile series..
Rockford 6.5" Fanatic Q's and X's (Have both cant remember which was which... silver cones.)

May consider leaving this in for track days!! Playing a bonkers cd... that normally used to make me drive faster...

David

Well having thought about it!!

I would have the Twin unit Nakamichi Cd transport and Dac( Never sold in UK)the one with a huge volume control

Then a custom made Genesis Mono Sub amp pushing around 400 watts
Another Genesis amp maybe 4 x 100 watts for the fronts.
2 x 10.inch JL Audio Dual voice coils( Latest models...Not 10W6's Adam!!!)
For the fronts I would still have DLS's top component system Think they are the pro series.

Then I would have "Prestige" or "Sound Gallery" install complete with top cables and sound kill. But having the front speakers placed in nice sealed cabinets
well down in the foot wells.

Thats me happy!!

David_Wallis

My Nakamich Was the Second In the country... It was BBG's Own but my first was faulty so they swapped it with theirs... I had it months before the magazines reviewed it... and they reviewed the non rds one!

David

chiark

David, you don't need that 215x - flog it to me

kryten

Pretty much got there, then rolled the scoob:

Alpine 7969 head unit (no different to my 7939 sound wise, just more lights!)
Alpine CHA-S624 CD changer
Alpine PXA-H600 processor (optical links, decent DACs, Time Alignment!)
Soundstream Continuum Amp: ltd edition £1400 new! (bridged for fronts + sub)
Soundstream 804 (bridged to run rears)
Infinity 60CS rears (for the kids only)
Dyn System 240 Mk2 in door builds (System 360 was a bit too big)
Single JL12W6 in sealed box

Was considering adding a digital EQ in link with the optical connections to give 2 x30 bands fully digital EQ. Or the newer PXA-H900 with 5 x 32 bands of parametric EQ!!

Sounded excellent (but I'm biased) and went loud enough to be uncomfortable (and cause hearing damage).

For anything better, I think you really need to get into separate transport/DAC. I know one of the guys at Wentworth put a Naim transport/DAC pair in his car for a while, but they had some issues with power supply stability!

Of course, some of the expensive horn setups (ie 4k+) do sound better but cost a fortune and are a pain to fit.

Oh, I'll be deciding in a couple of weeks if I'm going to bother putting it all into the BM - if not, you could buy a complete dream system........

chiark

Hmm, ok, let's think...

Would have to audition both Focal and DLS fairly heavily to make my choice, or stick with CD tech stuff that I do like a lot...

Amp would be Soundstream Da Vinci. That'll do.

Subs - again, have to audition, but I think Diamond Audio would be up near the top.

Head unit. hmm. Hmm. Do I go for DVD with 5.1 decoding or not .

I am starting to consider a monster re-install...

audio g man

I'm quite happy with what i got

Almost.

David_Wallis

Chiark,

You can Have it if you want it... needs fixing... as one channel is playing up... but if you want it you can take it!

David

David_Wallis

Kryten... Very Nice..

Chiark I know what you mean about focal etc... would have to have both in the car back to back and then decide which you prefer... but for me its power handling and then quality... You should see the size of my 6.5" Power Series mids.. They would probably only fit in a volvo!!

David

the link

I think i have mine for now
Alpine 7969 head unit
Alpine CHA S624
Diamond audion S600s Hex components
Diamond audio MacDaddy 12in sub
Phoenix gold titanium base cube
Phoenix gold titanium EQ232
Phoenix gold titanium powercore 15farad cap
Phoenix gold titanium 600ti amp
Phoenix gold titanium 400ti amp

system based on SQ and not dB but does play pretty loud as well

Paul_M

Can't believe there's no mention of the Alpine CDA-7990R and PXA-H900 combo. OK it costs £6000 for that pair alone before you consider the rest of the system but it's pretty fecking good, 120dB SNR speaks for itself .

I think it'll always remain a dream for me tho

David_Wallis

Paul_M,

Thing is though, without an rta meter, do you reckon there is ANYONE on here that can tell the difference between my MB100, a 7969, 7990R, Becker, Mcintosh?? Ill provide a Kenwood MP6090R and MB100 for the challenge

Mine comes with external DAC as standard however a 120db SNR is pretty good..

Anyone knows the Nakamici units I have mentioned?? I think they are only sold in USA?Japan. Very expensive and has a huge volume control dial on the front??

Luke

David

the one I am on about has a HUGE volume control in the middle of the unit. I think its just a preamp then you have a DAC/transport to go with it... When I was at BBG (Nak Importers) they said it was out of this world and cost ££££££££ But was not yet available over here.

Come on guys (Adam/Nick) someone must know..

David_Wallis

Ive never heard of owt... somebody might have but I doubt it.

David

steve McCulloch

David

I must come and listen to your set up!!!

Mines are fairly basic affair. IMHO the Dyn's are in a totally different league to the 'poor' cousin Focal components (then again I only forked out £300 for them...... nasty......)

Best set up I've heard to date for sound Quality definately Krytens - followed by Leeds Car audio for power..(RF head unit, plenty of Genesis ampage, Dyn Audio fronts and DLS subs, RF equaliser and the whole car was dynamatted!) the only system that can take on New Orders Confusion (Blade) at very high sound levels (a mate nearly passed out in the rear of the car)

David_Wallis

Unfortunatley as I got banned I pulled most out with the intention to sell it all but couldnt bring myself to do it... Ill get some photos for the an Idea though... Hang on..

David

steve McCulloch

You can listen to mine then and tell me how to improve it!!

David_Wallis

David_Wallis

Steve,

No problems, but my opinions might be different to yours! Besides I wouldnt mind having a ride in, or at least looking at your car / engine! (Need some inspiration for mine... Now its almost track dedicated when its finished!)

David

Paul_M

Probably not, but when you're talking about the ultimate sound I suppose the more accurate and clean every link in the chain is the better (even though it would need an RTA to tell the difference). Whan you get to that kind of cash/performance level improvements are really beyond the human threshold and is simply aimed at better points in competition.

Here are the measured specs of the F#1 status units, although it's worth noting that even the humble 6-disc changers have 24/96 burr-brown M-DACs on board giving 105dB snr for us mere mortals

CD SECTION (CDA-7990R)
MAXIMUM OUTPUT LEVEL: 4.5 volts
FREQUENCY RESPONSE (20 to 20,000 Hz, referenced to 1,000 Hz): +0.10, -0.6 dB
CHANNEL SEPARATION: at 1,000 Hz, 99.2 dB; at 20,000 Hz, 73.4 dB
DYNAMIC RANGE (A-weighted, referenced to 0 dB): 94.4 dB
S/N RATIO (A-weighted, referenced to 0 dB): 127.1 dB
THD PLUS NOISE (with 1,000 Hz): at 0 dB, 0.003%; at -20 dB, 0.03%
D/A LINEARITY (at -90 dB): -0.05 dB
INTERCHANNEL PHASE ERROR (at 20,000 Hz): 1.7 degrees
DE-EMPHASIS ERROR (at 16,000 Hz): 0.01 dB
MAXIMUM DEFECT TRACKING (with Pierre Verany Digital Test disc): 4,000 micrometers

OK I can't find the full specs of the H900 on the net and can't be bothered typing it up from the brochure so here are a few quotes!

*REAL TIME* time alignment....i.e. you can move that setup mic wherever you want, and it'll time align for it

*REAL TIME* auto adjustment of the 31 band EQ (one for each of 6 channels) to keep the RTA to a predetermined curve...i.e.... start adding more road noise, and the thing will keep the freq balance perfect at any volume by comparing the source signal to the mic input.

David_Wallis

Thats the thing, you cant tell the difference between cables, x overs, dac's etc but bung them all together and get 3db then your shafted!

I nearly bought a cd-max myself... sometimes wish I did, especially with the AI-Net Sh1te...

You Live and Learn

Still wouldnt swap mb100

David

It aint that fast - the stereo gear ways it down. I suspect the 0-100 is just under 10 seconds - shabby - should'nt be hugely different to CraigHardmans old car as he was running 1.5 bar on the Banzia? thrash...... on the samee turbo and some similar mods.....

0-60 suffers cos of the huge turbo.....

The Tweeters on the Rockfords are tiny... so much smaller than the Dyns! - what do I know - I know nothing whatsoever about stereo gear....

audio g man

I'd kill for the Dynaudio's and swap the car for a cd-max. hehe

David_Wallis

Chiark can vouch for the size of those mids!

David

chiark

I can indeed - 'kin hoooge.
