I have had most of them and still have about half ūüėČ C.A. as @muon*¬†said is a competent player and I fixed 3 of them. Good, solid engineering. Faults were¬†mainly trivial. I do have two Sony C

He Lampizator is entitled to his opinion.  The Stable platter mechanisms offer much advantage, vs no support of the disc whilst rotating, as the player then has far less error correction duty.

Okay, so over sampling is trying to turn a regular cd from 16/44 into a hi rez format, is that right ?

Okay, so what is the correct term for what I am describing ?

Well i was not clear.

 

over sampling is used to improve resolution and signal to noise performance.

 

Earlier I gave the reason why they used it with the TDA1541, which is pretty much the same as they were using it to improve noise performance by shifting the high frequency noise to higher in the frequencies.

 

I'm not sure what you were trying to describe, if it was players that state 'Up Sampling" then they might be players using higher resolution DAC chips. Having the ability to 'up sample' a signal 44,1 to a higher sample rate.

 

I was taking it that you meant over sampling which was used with older DAC chips.

Yes there is.

 

Might be better to link Glen to explanations of each one.

Okay, I am just trying to understand it all myself, so, are there, getting a bit off topic here, no matter, any cd players and/or amps that try to, ah, maybe this is the correct term, up convert ? a 16/44.1 to make it into a hi rez  ( 16/44.1 into a 24/96 ) signal/sound ?

Yes, probably any modern one.

 

I'm likely not one to ask as I kicked the up sampling habit a while ago :D

I used to have a Behringer SRC and i preferred the sound with it set to not up sample, but with Dithering engaged.

 

Edit: i find up sampling to sound different, some like it and some like myself do not. For myself it smooths the sound but at the cost of a little bit of dynamics. Pick ya' poison.

 

MattyW has a DAC that uses Philips first chips the 14bit/44.1kHz TDA1540D operating in non over sampling mode, so no over sampling and definitely no up sampling. I would put it up against any modern DAC or player where being feed red book is concerned.

 

Edit: oops! I left out the 'k'

Morning Ian,

‚ÄėI will profess to being of the same school as you.

I am not a fan of up-sampling and have listened to a lot of devices that allege to do it well.

I consistently find a sense of ‚Äėwhiteness‚Äô is added to the sound and the natural harmonic decay in notes is¬†negatively impacted. ¬†
I would describe the end¬†result as ‚Äėmore detailed‚Äô but in an artificial and un-natural way.

(your description above is apt )

i have a Chord Hugo TT2 and the associated upsampler for it which I am babysitting for a friend and I personally find the upsampler to be terrible.  Using straight Redbook as input and using the built-in output stage as the amplifier (approx 18W output) it doesn’t sound too bad.

Add the upsampler to the combo and it sounds White, Bright, and artificial.  I was staggered to hear the difference.

Still prefer the sound of the KDAC with TDA1541. The transport I use runs in NOS mode.

More natural and musically engaging but the Chord is very good when fed as an analog output into SE valve amp.

Cheers

Rawl

ps We are going to catch up in the early months of this new year??...

what are you using as a transport, a modified Marantz 94?

This is what unmodified CD-94 MK2 SPDIF output looks like... Not ideal.

All Marantz players appear to have such output

If Rawl is using a 94 as transport it will be highly modified and will not have any compromises like that.

 

In fact he is may be feeding the Killer via i2s.

Hi Ian,

You are pretty close.

I have a 94 which has had extensive power supply mods,, complete clock replacement running I2S as you expected in NOS mode.

On the other system I have a Wadia 3200 with full power supply mods, full clock replacement (using a car battery to power the clock) also running I2S.

I also have a 94mkii , similar PS mods running a zenelectro Zen-clock which has oven controlled oscillator and full reclocking circuitry.  Also running I2S but this one also outputs spdif if desired.

Fun to change them around.

They all have their own slightly different signatures.

 

I am slowly getting off my butt to finish Axiom 80 system but this last year has been crazy busy for me.

I so feel for folks in tourism and a lot of small businesses that have been crucified by the lock-downs and related measures.

I have all the bits to build a Type 50 SE amp (or PX4) for the axiom 80s but not enough time or energy.
I have a nice little 2a3 as a possible interim for said system

It will have a KDAC plus one of the Marantz’s.

Am also experimenting with USB  To I2S input with full buffering/reclocking to be built into the KDAC (supporting up to 192 or possibly 384 in simultaneous mode) but nowhere near enough hours to finalise this yet.

 

Too many projects, not enough life.........

Lovely stuff, Rawl :thumb:

 

What's your opinion on the CD-85's, the OP in this thread is looking for something TDA1541 based and one option while not cheap is a recapped CD-85 with NOS mod

 

I've read they are nearly as good as the 94, but you have heaps more knowledge on these players than I do.

Hi All, I am not singling out any Dac/chip in particular, I am after something that is quality, sound and build wise and the one’s that I have mentioned is what I could buy now, as they are available.

Off topic but I found a type 50 ST shape in my tube stash the other night and it looks so darn¬†sexy. I mistakenly took it as a 2A3 foraging through all the ST shape bottles I had in this¬†box. Re the 2A3, I have a Sun Audio SV-2A3 that sounds brilliant and is slowly pushing it's way ahead of my two 300B amps and 845 amp. ūüėĀ

Hi, I had indeed a thread specifique to TDA1541 players but as this one is more generic, I am posting here instead. 

I was looking at modified TDA1541s, but at the moment there's nothing specific I am able to get fixed on, plus there's a risk with buying from the UK (due to Brexit there's a lot of confusion and people get charged extra taxes for buying in the UK despite the agreements made). Have decided for now to buy a non-modified player and star there. 

 

Yesterday I bumped into a Rotel RCD971 with the BB PCM63 DAC. According to accounts I read, this is also one of the legendary multibit DACs, and for 200 EUR this looks an interesting opportunity. Anyone had this player?

Welcome, I have read your thread, continue here, no, I have not heard the Rotel that you mentioned, maybe someone else can chime in !?

I had the more upmarket one, RD-991 with the same DACs but also PMD-100 HDCD chip, adjustable dither, full of Black Gates, Nichicon Fine Golds and Muse, WIMA, 

It looked like the best made CD player inside and I bought it because it was the cheapest balanced player available at the time.

Sadly the performance was pretty average and at the time of sale I finally found that it was not balanced at all. The cold outputs were merely inverted by a set of op-amps.

Inside looks great but pretty average.

I'd just up your budget a bit and grab a Rega Apollo and be done with it.

I have thought about the Rega cd player's, a lot of reliability issues, that I have read about though, doesn't happen to everyone, but it seems to occur more than not

Somewhere in a friend's loft back in the UK I have a mint first generation Marantz 63 I see a recapped one going for ¬£1999¬†ūüėĶ. I bought s/hand in 92 a Marantz 63 KI used it for 26 years. So I like the Marantz sound.

 

Are you set on buying a vintage CDP ? Here's my suggestion - the new Marantz CD6007 it's a blinder. Completely walks all over my old 63KI. What your buying is 3 pieces of gear in one box. It's a big piece of gear and it needs to be as it has 4 separate boards - PSU, analogue,digital and h/amp. The mech is absolutely silent in operation. Marantz describe the h/amp section  as audiophile quality and I'd agree. Dead black background, a stunning sound stage, bass is multi layered and using Oppo PM 2 h/phones I have never experienced before the feeling that I'm not listening through h/phones and after listening for a few hours no ear ache. the Marantz and the Oppos make a perfect combo (for me).  It didn't take many hours to convince me to sell my 2 heavily modded Dark Voice  and Bada PH12. h/amps. Listening through my Heybrook Sextet Mk 1V speakers, CD has never sounded this good.

 

The digital board will accept virtually all types of input. I hav'nt used it yet, waiting to buy a Puffin as part of digitising my LPs but I'll bet it's on a par with the h/amp. I get so hacked off when manufacturers use in your face LEDs, there is a tiny red LED  over the on/off push button and when on, another tiny LED in the corner of the info screen.

 

Find a Marantz dealer and take a listen,¬† one of my best audio buys ever. I've read lots of opinions on new v old CDPs¬† and I'd agree that a lot of the current CDPs¬† are streets ahead of the old ones. I paid ‚ā¨415 for mine.

 

Take a demo and come back with an opinion.

I am yet to meet anyone who has any knowledge on the matter who would suggest that current players are better (let alone streets ahead) of the players from 80s and 90s.

Look, this guy is trying to buy $2000 player for under $200 and you are suggesting that he buys a $399 one? Admittedly it has a competent AKM DAC chip, but it still is Sigma-Delta one coupled with $10 mechanism. Which works nice and quiet, because it is brand new. Wait a couple of years and it will be due for replacement.

Thanks for the suggestion, I have decided to buy something like a Oppo or a Cambridge Audio all in box solution, then save a bit more for something really special as a stand alone CD player.

¬†You talk about knowledge, I'm talking about what I hear and not only with the 63KI but other 20 year old plus CDPs. I hear details and instrument separation¬†¬†that I have never heard before. The 63KI I bought was already 2 years old and the only part to fail was the on/off button. The CDP being touted is just that, the¬†6007 is 3 pieces of gear in one, I can vouch for 2 of these. Does the OP want to use high res download¬†format, he can with the 6007¬†So, a CDP/h/amp and a digital player for just over ‚ā¨400, I ¬†all that good value with a great sound.

 

Also there are 2 British makes being considered but as at least one poster has said be careful about quality control and longevity. Sadly quality control with many British products and not only in audio is a foreign concept that a lot of British companies havn't got a handle on yet after decades. There is another thread I have to get back to soon where I mention how atrocious some aspects of the construction are of my Heybrook Sextet speakers, a great design by Peter Comeau before he left Heybrook but where were the inspection points and of course final inspection.

 

Hats off to Marantz they don't turn out badly made gear ever. The one negative with the 6007 is the top plate, it's very tinny, tried using a 20mm deep piece of polished slate and a piece of chipboard - the chipboard had the same damping effect which surprised me. The OP can as I've said can find a Marantz dealer  and use his ears. It would be good if he did that and got back to the forum - theory from practice - nothing better.
