Marantz CD63 & CD67 mods list

Awright boys....

...found some lovely hifi pr0n over at 'the tent'.

hifiwigwam thread

There's a Marantz CD-7 with no clothes on page 2, just for those that go cold and shudder at the mere mention of the word HDAM. There are eight of those shiny little b*stards staring back at you.

By the way, if anybody wants to see the insides of an Arcam Alpha 7SE, let me know. Just fixed one for a mate (new laser was needed). One interesting thing I noticed was that there are no electrloytics bypassing the op-amps (which are NJM2114D a la CD63 by the way). It sounded quite lively but very coarse. Easily bettered by my 67 and also a lightly-modded 63 I have lying around.

Laters.

Some nice gear there.

Here are some pics of the Arcam CD73 I modded PIC1 & PIC2

I found the overall design fairly limited with regards the psu and rail seperation but they used some good quality caps. The sound was crisp with decent timing but lacked soul and balance (as with so many cd players).

By the way - and seriously OT - I'm trying to figure out the best way of getting music from PC (lossless) to DAC. (Squeezebox Duet vs Apple AE with iPod touch as controller, etc.)

So I started looking at starter DACs to use... Cambridge DacMagic and Beresford TC-7510. Everyone goes on about the fact that Stanley Beresford will give you your money back if you don't like it, so I checked with him.

He himself told me he doesn't do that anymore. He could have left it at that, but he actually told me to go and buy the Cambridge instead!

Just thought I'd share that as it made me laugh!
 
Ooh... I wonder if I could squeeze a few of those Twisted Pear boards (stacked) in the far corner of the amp?

S/PDIF receiver + Buffalo (ESS Sabre) + IVY (I/V stage) + Reg board....
...plus a couple of small transformers.

Remove the phono board (no TT these days) and use that input.

Silly?

LOL! That's wonderful, what a guy.

BTW, that stuff on Wigwam is RAZZLE-grade top shelf material. The Copland CDA288 made me come over all funny.

The Cambridge got a good review in what hifi but it is £80 more than the Beresford and also looks nicer

You could try it, although there is minimal room to add stuff.

Also I noticed you have not modded the amp, get a second KI tx added, makes a large difference and also put in some nice input caps as the silmics are poop!

Cheeky Stan lists his prices without VAT and delivery.

I work near the London Bridge Richer (the original and still the worst!) so wouldn't need that delivered.

A black Squeezebox 3 (aka 'Classic') atop a black Dacmagic would look OK actually as they are practically the same width.

Fair point! Although I don't like modding two things at once as you kind of lose your reference point a bit.

I'll get around to tarting it up one day.

I think the SB route handles internet radio better than the Apple route, and I'm quite into that these days.

By the way (major OT alert) I'm currently using a cheapo £35 Curry's 'Logik' internet radio adaptor that I bought to experiment on. It uses the 'Reciva' database. It was the worst sounding thing I'd ever heard! Loud mains hum, really muffled, and it sounded like it had some kind of 'megabass' switched on. I literally laughed my c0ck off when I heard how bad it was.

I noticed it had a Wolfson WM8721 DAC in it, as used in the first few generations of iPod (they now use Crystal DACs by the way), and can these early iPods sound great with the right material.

I completely removed ALL of the analogue circuitry and hooked up the outputs of the DAC itself to my amp. No hum, no megabass, but still muffled. Firmware bug had de-emphasis on! Managed to hack the firmware (long story) to disable de-emphasis. Now sounded quite good, but lacking oomph. Made a small buffer board (LM317 and a BUF634 open-loop buffer per channel) now sounds bloody marvellous! Listening to it right now actually. I went a little overboard on the buffer (Pan FC on reg, Muse KZ on buffers, BG NX i/p to buffer, Silmic on o/p!). I had all of these parts lying around anyway.
