Burn In Period Bypass For ZROCK3 / Level 2 mods?
04/15/25 at 16:24:45
 


My Zrock3 with level 2 mods, and tube regulation is on the bench now, and should be shipping soon. (perhaps next week)

Here is my question:

During initial burn in period which most likely will be in excess of two hundred hours (about 20 days + for me), is there a way to BYPASS the output where it does not affect the sound of my system during the burn in process?

My system is at a level right now where I just passed the burn in period for my new tube DAC, and it is now sounding absolutely superb to say the least. I do not want to endure another dull burn in period as I use my system now just to get a new piece of equipment up to full standard.


In other words, can I hook this unit up to be on when I listen, but set the output to zero and still get the benefit of normal burn in?

If not, then I will have to set up another system using a SS amp and a source to burn this unit in at another location in the house. I will just leave the system in constant loop on low level for a few weeks until it is ready to be placed into my audio room in "ready" status.  That would certainly expedite the burn in process.


I read another owner's comments stating that this unit sounded so horrible during the burn in process that he almost sold it with only 50 hours on it.  Then around the 200 hour mark, the unit bloomed as if it was a butterfly undergoing metamorphosis from the cocoon stage. Now it was as if a magic wand was waved and the unit came alive.

That sounds great, and I will wait patiently for that to happen.  But in the meantime, I don't want this to ruin the perfect level of sound quality that I currently enjoy using premium quality recordings.

Perhaps Steve would be best to answer this one, but any response is welcome if it actually comes from experience using the ZROCK3.


I shall be experiencing this unit very soon. Just not in a bad way.

Thank you.

No, because the sound signal needs to go through the components within the ZROCK.

I don't think you need to do that. You can just run your source through the ZROCK when you aren't listening to the main system. No need to actually run the ZROCK into an amp that is amping.

Good luck regardless. You may have a different experience than the other poster and find that even before it is burned in the ZROCK is an improvement.

You could try using a Y-splitter to split the output from the ZROCK3 to a secondary amp (or dummy load) while keeping the main system muted. This would still allow burn-in without affecting the current sound quality. block blast

Of course, unlike the previous ZROCK2, it could be bypassed with a switch. That feature REALLY needs to be re-implemented!

In my situation, I have a vast collection of premium recordings which absolutely do not need this unit in the signal path. I only bought this to help rectify the overly compressed standard issue recordings which I can't replace with premium recordings which do not use compression limiters or filtering to destroy the original master recording during the transfer process.  Telarc audiophile offerings from the 80's were a good example of this.  I have many Classical recordings under the Telarc label.  

Today, I am purchasing every HDCD, BSCD2, SHM-CD format disc that I can find, many direct from Japan where they are mastered. I have quite a few LPCD direct from master recordings as well.  

Obviously, there is zero need for any additional signal processing or "correction" factors necessary. My current tube DAC is as about as pure and natural sounding as digital can possibly get. I just want to inject the signal with lesser quailty recordings that need help.  HQ discs need to pass straight through to the amplifier to hear the DAC without any extra processing.

What I have done is to order all HQ audiophile grade parts to build a purist BYPASS box to do just that. I have some very high grade silver contact NKK DPDT  (ON-ON) toggle switches with LED indicators coming. I have a small metal enclosure to create this with. I ordered several sets of HQ Manley Labs gold plated/teflon RCA jacks for this also.  The internal wiring will be done with high purity silver wire and silver solder.

This will allow quick and easy bypass and insertion when needed at the flick of a switch.


Like stated, yes, I can simply break in the unit for now with just a source feeding a signal to it, leaving it on continuously for a couple of weeks to get it seasoned properly. OR, just insert it in the system now, simply bypassing the signal when I am actually listening.


I will be doing extensive reviews concerning the use of this new ZROCK3 using various grades of CD quality. There will be a great deal of A/B testing if you will concerning this.  I will be providing extensive in-depth details about the performance of the ZROCK3 in my system with a great deal of comparative listening.

The ZROCK3 should have shipped out from Decware today, so I hope to get it by next Tuesday.

As soon as I get it, it begins the break-in period.  I will be sure to listen to it in the fresh green stage for future comparisons as to how it improves over time.  Then it shall remain quiet in the system until it gets a good 200 hours on it. (just a couple of weeks continuous play in loop)

Yes, that is a good suggestion, but it won't be necessary with my bypass switch box coming soon. Thanks for that suggestion.


Okay, well I have this under control.  I do appreciate the feedback.  Keep an eye out in the near future for continuous reviews coming from me concerning the ZROCK3. You may find it interesting.


I will be starting a new thread in the digital section which pertains to my new tube DAC builds in the works. These will be the premium components used for the comparative testing.  I will get started on that new thread in the next week or so.


I have many new HQ Audiophile discs, and many more coming. I shall see how these compare with standard Redbook CD's rectified by the ZROCK3.



Later.
