Default Additional digital output on Teac VRDS players

Hello,

I think most of you are familiar with the Teac VRDS cd players/transports. They are also used by Wadia in their cd players.

Currently my cd-playback is far worse than vinyl playback, and my turntable is very old. So, time to upgrade.

I really would like a seperate cd-transport with a teac vrds transport. Unfortunately, a second-hand wadia is a bit too expensive for me. So, I might opt for a Teac VRDS-10 or -7 (or a T-1).

My question is: Is it possible to add an true AES/EBU digital output to Teac VRDS players? As wadia uses the same transports, with AES/EBU outputs, I think it's very likely that it can be hooked up somewhere. I would like to know if any of you know if this is possible, and if so, how.

If anyone can give me information on what vrds player to avoid, or to get, that is also appreciated.

And oh yeah, I'm planning to run it with an outbord dac, a parasound dac-1600hd, if I can find one..

Thanks in advance,

Terry.

Terry,

I use a 10 for 8 years now. I'd reccomend a T1 or a 10. i modified many TEACs, for friends and customers. They are great machines but need attention.

At the risk of being too commercial: I offer a new clock board with additional reclocking to add a secondary digital output.

regards

Thanks Guido,

Do you know if the T-1 is transport-wise the same as the VRDS-10, or are there huge differences? If not, I think I'll get the 10, as I don't have a dac yet.

I am also curious why they need attention? Do they have a lot of untapped potential in their unmodified form?

A new clock would also be very nice, but if the dac has a reclocking feature this wouldn't be necessary? Also, is this digital output a aes/ebu balanced version, taken from the transport as soon as possible?

Hi

The T1 has a spin off transport from the 10, like used in the 8 and the 9 (avoid the 9, terrible to work on constructionwise)

Off the shelf, I prefer the sound of the 1 over that of the 10, small difference though.

These drives can be made to something that realy smokes aCEC, to mention one.

Reclocking SPDIF is ALWAYS helpful, the lower the jitter that enters the DAC, the better.

The digital output is SPDIF, 75 ohm. AES / EBU is only used in studio's, uses XLR for RF transport, niot my cup of tea......

I propose true 75 BNC connectors and interface for digital, in home use. Works very fine when done right.

The signal is taken of the decoder, then reclocked and buffered, goes through a transformer and is then ready to enter your DAC.

all the best

Thanks,

You are right about using 75 ohm BNC plugs. But I have seen a lot of (expensive) transports and dacs that use the AES/EBU interface.
I might opt for the SPdif interface then.. I still think a balanced connection will provide more benefits, if properly implemented.

Speaking of balanced.. Do you know if the 10 has a balanced analog output?
Also, do you have a site with information about your clock?

Hi

Audio industry is a weird industry. They run after standard applications of semiconductors industry and put price tags on it - no guarantee for good sound...........

The 10 has a single ended output which sound lousy to my ears (that is why I designed my own DAC and clocks)

My experience is that the extra electronics needed for balancing spoils the overall performance.....

No website yet, but mail me offline for more info

Consider the VRDS 20 also. Built like a tank. Mine sounds v good with LC Clock.

Hi

A 20 is "just" a 10, some more expensive components, as far as I know.

If you look for a drive only, I'd go for a T1 or a 10, do not pa anything more than that.

The LC clock I measured looks like an FM receiver........

best regards

Guido

This may go against the "audiophile rules" but try using your computer as a transport and take the digital outs off the sound card into your hifi's DAC. I have the T-1 and D-T1 combo and this sounds good.

I had read a few times in hifi news about the benafits of using a PC to replay digital audio. (This is only if you use something like Windac to copy the CD to your harddrive and then something like FooBar2k as a player). It all revolves around the way a computer handles data, it buffers it all then uses it. Im not 100% sure about the pros but its something like it gives a jitter free and perfect data stream with no errors to the dac. Anyway I tried this using a PC as the transport thru the D1 and the difference was clearly there the PC sounded better no arguement.

I copied strauss 4 last songs and some Ella Fitzgerrald and then played it for my mums consumption. When I make some simple minor changes to the hifi I can hear them and she cant. Basically she commented on how stupid the hifi industry is as the total PC cost 300 and the TEAC 550, but the PC clearly sounded that much better.

The best bit is that you all have PC's and most will have a digital out. FooBar2k and windac can be d/l for free so this little test doesnt cost you a penny. Oh and btw if u use the standard 3.5mm to phono lead you need to use the left channel (the white one plug) into the DAC or no sound will result or if that fails the right :P. One other comment soundcards upsample everything to 48K then send it to the DAC. Soundblaster lives are shoddy upsamplers. FoorBar has a real time upsampler that uses your comps power to do this so the soundcard doesnt have to. One problem with this tho is it takes a reasonable ammount of power. The comp I use atm is a 300megahtz and cant do the upsample, the comp im typin on is 900 and can. But the 300 still sounds better then the T1 regardless of its "shoddy" upsampling.

Using my PC isn't really an option, it's mostly being used by my girlfriend. Also, I'd need to buy a bigger harddisk (laptop eh), to fit a few cd's on. That'll be about as expensive as a t-1..
