Don Sachs 2 vs. deHavilland Ultraverve 3

There seem to be quite a few discussions and reviews on these preamps, but I haven’t seen any direct comparisons (I have done several searches).

Both are octal / 6SN7 tube line stages, include similar inputs/outputs, have similar features including optional remotes, place the tubes above the case, and are similarly priced. I would be grateful to hear about how they differ regarding their:

  • Sound (reviews of both say they are detailed and also include aspects of the traditional/warm tube sound, but I can't tell how they compare to each other) and

  • Design and Performance (ie the impact of design differences such as 4 6SN7 tubes in the Sachs as opposed to 1 in the deHavilland or the 48 step Khozmo remote ($200) vs the 32 step deHavilland remote ($500), etc.)

I have seen at least one thread where a member discussed experiences with both preamps, but I could not see any comparisons (such as the Sachs was more [fill in the blank] than the deHavilland).

Obviously it would be great to hear from members that have heard both preamps. There may be members that have not heard both, but may have insights into the potential impact of their design differences, and I'd be interested in hearing from them also.

Thanks in advance for any thoughts!!

My point-to-point wiring comments were based on my understanding that the Sachs was based on the SP14 board from Roy Mottram at Tubes4hifi; whereas the Ultraverve is point-to-point hand wired (no board).  Also, the tube compliment that comes with the Ultraverve contains quality NOS tubes tested and specifically selected for the preamp -- at least mine did.  They are very nice quality tubes.  The 6sn7 will most likely be the only one that you may end up rolling if you are trying to tailor the preamp to your taste.  Mine came with a very nice vintage Sylvania that suits me just fine-- no need for me to roll at this point.  Just curious, what amp and speakers are you using and what type of music do you listen to?

4hannons,

Thanks for trying to place these on a spectrum and giving greater context by including other preamps. I agree that we can’t represent such complex sounds by a number, but in the context of a lot of other details (like those you gave), it can help as another piece of the puzzle.

If you have time for another comment…you mentioned the deHavilland as being “slightly warmer/darker”. Have you found it has more mid bass/low mids OR less treble/high frequencies...or both?  I guess I’m wondering if there is any sense of a veil or muted high end…

Gotog,

I get your comments now regarding the deHavilland’s wiring. Apologies as I think my question came from ignorance. Your post helped me to understand so thank you for that!

BTW, do you know if the deHavilland has anything that can help the user know where they are in the volume ladder (the Sachs has a digital readout for this)?

My amp is a McCormack DNA 0.5 deluxe and my speakers are Gemme Audio Tantos. (I'm a bit of a noob at hifi.)  For music, my first passion is jazz (Miles, Coltrane, Jarrett, etc.), my second is classic rock/blues/folk, and I also love classical and a lot of other, diverse stuff.  How about you?  Also curious if there is a genre (or speaker type) you find especially suited to the Ultraverve?

Swing,
Nice system...The Gemme Tantos are really nice..We have exactly the same taste in music..in the same order of preference.. As far as knowing where you are on the volume ladder, the Ultraverve doesn't really tell you.  For instance, when you use the remote to change volume it does not move the knob on the panel.  If you manually change the volume using the knob after using the remote, it will just increase or decrease the volume from where it was previously set via the handheld remote. I think it really comes down to what you are looking for to compliment your other gear and room.  The Ultraverve imparts just enough warmth (tube flavor) for me.  My room is a little bright and my speakers are really detailed, and it just smooths things out a little (not too syrupy), especially on recordings that may not be the best.

I haven't had experience with either of these units, but I have a friend with Don's preamp, and have heard nothing but praise from him.  His experience paved my decision to buy Don's custom phono preamp, which I love,

I am however, on my second 6SN7-based tube preamp.  My experience with both is that the tonal nature of these type preamps can be widely altered with tube choice.  To a perhaps an even greater degree, selecting different input tubes changes the character as well.  Have fun with either choice.

As to how tubey a unit sounds, I have found that the most tubey sounding preamps are tightly tied to coupling caps, and those more SS sounding work to minimize that or eliminate them entirely.  My current unit is likely closer in sound to Don's.  I love tube sound without any cap or transformer haze getting in the way.
