Wait time is.... 1 hour for us to pack and print out the docs for shipping.

Currently we plan to offer custom gain, which you can specify the gain you want between 1 to 11 (11 is default) for $5 extra to cover the labor charge. Of course, with this option, the wait time will be 1 to 2 days instead of the time we need to just pack and ship.


Thanks

I recommend gain of 1/2 for anyone with easy to drives. If you don't have your volume loud you'll find low gain is sufficient even for HD650s.

What about the K701's, also why would a low gain benefit.

the GAIN ,is it worth changing from the default 11,what benefit would I get, also I would be using headphones across all impedance's to 600ohms from grados

High gain for some users can be a problem, because that with a source that have slightly high output and a sensitive heapdhone, it can get real loud. While turning down the volume on the headphone amp does help, the "early" part of the volume pot does not often sound very good or are very balanced. Usually the volume pot performs better when it is at around 9 O'Clock position and on, before then it could have a bit of imbalance at the start, and gradually balances out when it reaches around 8 to 9 o'clock position.

Thanks

Would you recommend lowering the gain to run the Grado SR325is and AKG 701's

It depends on your source [output voltage]. 4 might be a happy place.

the source would be my laptop to D4,its line out is somewhat low at 1.5 V rms, therefore I'am not sure what Gain to go with.

What is the gain of your current RA-1 clone/CMOY? Perhaps we can figure it out from what you currently use.

This upgraded HA-006 +++ sure looks like it will be a fine amp for those looking for a great sound. Sure look forward to hearing one, perhaps at a meet.

Thank you for the current info and heads up. Dead right on the gain issue, has been frustrating me out of my mind. Thankfully ampmakers are opening up to custom for this issue.

I am very tempted towards this amp as experienced posters knowing the value of Dynalo has given their blessing. Would it be possible to present this amp in balanced mode ? Maybe H-006+++ balanced, if too far from commercial viability, would be happy to fund some experimentation if not a too far fetched thought. Ownership of prototype desired.

We can dream and ask no?

Newshade.

I feel the + marking will have to stop somewhere... You know, even C++ didn't evolve and named C+++

As for the balanced model, I'm thinking about it, but we don't have a schedule on that at the moment. However, if we do try, I do have a pair of AKG K271DF modified to take balanced input (using K1000 compatible plug, I prefer this over two XLR plugs), which should allow us to evaluate how much of an improvement does the balanced version do.


Anyways, we are currently working on other projects that should result in interesting products for those who might not be exactly interested in DynaLo. I will be able to post a bit of extra stuff once we have some concrete results.


Thanks

David
