View Full Version : Why not Transporter Home Theater Bypass Loop?

Given that the Transporter can (theoretically) REPLACE a pre-amp for 2 channel listening, why not include a Home Theater Bypass Loop in the design? That is the ONLY missing feature preventing me (and probably lots of other folks with combined stereo and home theater setups) from buying one.

I see folks (in the Audiophile section) are asking for a DIGITAL bypass loop. From my perspective, an ANALOG bypass loop would be even more useful.

Of course, there would have to be either an analog or digital switch (if not software controlled) to choose which input's/output's are active.

Absolutely right. The absence of Home theater bypass is a big mistake. How much more could a simple bypass switch have cost? I am unable to elegantly integrate my home theater with my 2-channel set up because of this problem. It's really very annoying.

Same here. If it had such a bypass, I would have owned one already

I read your post but none of you have listed what HT gear you have. You can see my list below and my AVR is the main reason why I jumped on this SB bandwagon. Both my old Pioneer VSX-26TX and my newer receiver have the ability to by pass any signal analog or digital to a direct mode. My new receiver can uncompress downloaded music back to its original state (via optical connection).

That's now twice you've made that fascinating claim. Care to back it up?

Please do give us the reference, I'm dying for a good chuckle...

Check the spec for yourself on each of the Pionerr Elite VSX 81/82/84 TX receivers

under the section covering sound retriever page 30 in manual

I looked, and didn't see anythink like your post of "My new receiver can
uncompress downloaded music back to its original state (via optical
connection)."

Where on the site is this stated?

I see nothing about restoring compressed music. I could be blind...

if you open the manual for the Pioneer VSX-81/82 or84TX check under the section that covers the sound retriever its states "When audo data is removed during the WMA/Mp3/MPEG-4 AAC compression process, sound quality often suffers from an uneven sound image. The Sound Retriever feature employs new DSP technology that helps bring CD quality sound back to compressed 2-channel audio by restoring sound pressure and smoothing jagged artifacts left over after compression."

Word for word from the manual for those who could not find it.

Sounds a lot like that 24-bit Crystalizer used in Creative's X-Fi sound cards.

That's not at all what you claimed.
"helps bring ..... back" is not the same as restores to original form.

"Sound Retriever" is clearly shown as a feature on their site.
It says nothing, and I expect does nothing, to restore the signal that
is removed during MP3 and similar lossy codec compression. These codecs
work by throwing away signal that are masked and not judged important
enough to take up compressed space.

It may be good, it may make MP3s listenable or more enjoyable, or
better. They don't claim what you claimed, that it restores it to
the original state. Using a lossless compression makes it trivial to
restore to exactly the bit perfect original.

Of course, if Pioneer published some details on what they are doing, one
could write a suitable plugin for the SlimServer....

I'd love to know what "sound pressure and smoothing jagged artifacts "
means in the real world.

Just stating what Pioneer says, and if it restore a file to CD level is that not better than the downloaded form? or are we going to go around in circles about wording of restore/original. just as in the movies when you buy a disk that says re-mastered or thx mode from master.

Er, no, you are doing more than even the Pioneer marketing dudes would
dare say.

Even here, "restore to CD level" is not justified by Pioneer's marketing
or known engineering.

If you like it, great. but its not a realistic requirement for
SlimDevices' or any other group of engineers.

The reality of lossy compression is that it loses sound. Period.
You can argue that what is lost is not important, and millions of iPod
users prove that it is not important to them. The best you can do it
recreate some of the quality of the original music. To get it all, you
have to use lossless.

I don't care to get into a discussion of whether or not is is good
enough for you, that is a personal choice that you and only you can
make. From an engineering point of view, what you have claimed is not
substantiated. Further discussion is not going to change that.

I agree fully, I was told to back up my claim and I did according to the information provided by Pioneer. If they don't go into detail how their feature works is no fault of mine. And most other companies would do the same on features of their products. This feature is one reason I was even interest in a SB, I love music and when you have to deal with less than ideal sound or find a way to improve the quality of your sound you will do so.

Now for all of you sound engineers in here, if you want to call Pioneer/Yamaha (their new flagship 2700 has direct cat5 connection for internet access and USB port for D/L music drives) and ask if they would share their information with you be my guess.


Ok, now that I have withstanded some flaming by those who have placed themselves above the rest of us plain folks. I never got my question answered to the original posting of direct bypass. And I only asked what type of audio gear (receivers) were they using that did not handle any direct mode or bypass.
