Well, I took time off my speakers and finally bought Linear Audio Vol 0 so I can read the piece on the inclusive Miller feedback. Now I know why I could not get it to work in Spice. I was guessing too much. By the simulation, it has a dramatic effect. It took me so long to get the DH-120 stable, and it sounds pretty good, I am almost scared to tear into it again. Naaa, Why not! With a new CD player and new speakers almost done, I might as well step it up another notch. The worst I could do is blow it up again. I almost bought a PA-5 really just to match the CA-5 and ST-7 preamp and tuner. It is too big for the shelf though. Empty boxes are really frustrating.

To get a new CD player, I was limited to only two. NAD and Arcam. Everything else is too deep. Can't say I am thrilled with the 565 but I have to get some new speakers in here before I condemn it. Through the Grado's, I am not sure.

As soon as the paint cures, I'll be able to see if I have whipped my wife's super hearing with the new speakers and if the Parasound beats the Rotel after all. I'm pretty happy with how this pair is coming out. Maybe by Sunday. If they work, I'll do a front port version with less BSC for my office and see how the NAD/Nak/Hafler sound.

So glad a Hafler is being used . I built the preamp from kits in the old days for my customers to save them money .

DVV , I had a wonderful time ( 39 C ) . Trapan wine is big discovery ( Bruno Trapan ) . .

You raise an interesting point . I have always thought car stereo sounds better than many home hi fi's if looking at the simple inexpensive end of the market . The package supplied with the car can be researched for a room that is always the same and repeated 1000's of times ( a VW Golf for example ) . The power source is quite good . The amplifier that results is more like a 1960's push pull with op amp bandwidth . The distortion not unlike a valve amp . I often wondered if one of those with decent speakers might make a very nice home hi fi ? Klipshe Forte 2 come to mind .

My encoded analogue compression idea was not well explained . The idea is to find a compression system with a very nice sound . My guess is a dynamic range of perhaps as low as 40 dB for standard use . It could even be transcribed to CD like that . The "encoding " ( squashing ) would be to a very accurate defined standard . Perhaps a 19 kHz - 50 dB reference tone at the start to inform a decoder and calibrate the system ? The expansion could be as said before controlled by user preference and room placed microphone . The ultimate idea is that the restored analogue is as perfect as you want it to be . If a true > 100 db dynamic range is preferred then it is available . I would also use a sound field microphone so that in classical music the microphone placement can be made to move . One day I might like to listen to a Bach concerto close up , another day in the cheap seats . Soccer matches on Sky TV use them ! I was also thinking a 32 bit 250 kHz storage memory might be an idea . This would mean loosing the purity of the concept for convenience . It would store for a second or whatever to allow level data to be recorded . Digital information would then be encoded in standard 16 bit 44.1 kHz . The CD that resulted would be perfectly compatibly with standard set ups and preferable . Although all digital , the compression would be analogue with a analogue expansion if required . The idea of 32 bit and 250 kHz is to record it also in other formats at the same time . The big deal is the expansion rates will always be identical from system to system . Only quality will differ . The system would do exactly what I did when recording . It would " gain ride " . My recordings were done with a full rehearsal . The conductor even taught me to read his intentions . The performance was always louder than rehearsal ( 20 dB often ) . I was told Herbert Von Karajan was able to control micro dynamics better than others . Thus Ravel Bolero was made more exciting his way . How a man with his past could be so good with impressionist music I will never know . Leonard Bernstein was great , however his Ravel and Debussy was no match for Karajan !! Talk about schmaltz .

I'm pleased to note you're happy with your vacation, Nige. That's as it should be.

Frankly, I don't see my car as a good audio environment. Nor do I much care, given that I am too busy considering all the options the surrounding kamikaze drivers and pedestrians have on their minds. Too little capacity left to concentrate on the music itself.

So I am not complaining about the compressions used, but I do wonder why can't it replay plain WAVE files from the USB source, I see no reason why it shouldn't, even if it is a cheap car. And frankly, this is one of my surprisingly (beacuse it's a cheap car) few quibbles with it, none of which could be classed as important. Surprisingly few trade-offs. So I'll live.

@tvrgeek

Frankly, your choice of CD players is, in my view, a poor one. I never liked NAD audio much, to me they're just another wanna-be company. While their CD players (at least, the ones I've heard) will do a decent job of it, that's all you'll get from them, just a decent job. Don't expect any revelations.

Arcam I don't really know, I heard only one of their CD players lately, I forgot the model designation, but it was supposed to be their middle of the range model. Again, nothing exciting about it, it's too polite for its own good.

But that's just me.

The car is a very bad environment . However the same prescription for each is a big factor in the success of this very humble equipment . We also have a pressure sealed cabin which helps . I would say many home hi fi's do not have the symbiosis that many humble car stereos have . I heard one recently with Martin Logan and Krell . No idea what was mismatched . It just did not work . The guy seemed oblivious and very proud . He also had more hi fi than any hi fi shop . Revox amps etc . The best example of outstanding correctness was the old B&O radio ( Beolite ? ) . Mono , expensive whilst not outrageous . 9inch x 5 inch speaker looking like TV speakers ( Dalquiste style ) . Sound better than most hi fi's . Bose seem to be recreating such ideas . I doubt if they are as good ?

On CD players if available try the Cambridge . They are cheap and have a very correct sound . My brother left me an Arcam , I find it boring .

The Rega is exceptional in my friends Naim system . He has a Naim CD player also ( CDI ) . I slightly prefer the Rega .

I had an Arcam amp and cdp once, Alpha 8 or 9.

The cdp was so so and replaced by a very secondhand and ancient Studer unit for a quarter of the price but the amp was easily the worst I've ever owned.

I know there are far better CD players. But NONE of them fit on a 12 inch shelf.

Holding off on the buffer or other DAC's, and even opening the NAD until I get my next set of speakers in here.

The digitally remastered Sgt. Pepper is a lot better than the original CD.

I see round display, long sharp stylus under displa, iron keyboard on the bottom right. What is on the bottom left, system block with wires on top?
