Lyra Titan i with a Manley Steelhead....settings??


Just got the Titan-i after trading in my Helikon to Hollywood Sound in Hollywood, Fla. Sounds great!

Question...what settings/configuration of the Manley Steelhead pre-amp would be optimum?

I'm running it through the MM inputs now (on the advice of the previous owner who said this avoided step-up transformer....etc and was purer sound). But, the Titan is an MC cartridge... so?

Also, regarding gain....what are the trade-offs? I've got the gain on the Manley all the way up on the 65 setting, and there's NO problem with volume when running everything into the McIntosh C-100 preamp. It just gets quieter, maybe less 'dynamic' on the lower gain settings....but, why would anyone want less gain?

Then, there's all those Load capacitances and Z's to choose from....... Can't say I hear any differences twisting the knobs. Whassupwiddat?

Any help//advices welcomed.

Thanks, in advance.

I wouldn't agree to avoid the coils on the Steelhead, I love the coiled coupled inputs, but I have tubed system. I hooked up solid state amps a couple of times, and what sounded good through tubed amps sounded almost phosphorescent with the solid state amps, so whether you use the MC or MM might be a matter of taste or system matching or the tubes you use in the 6922 slot. I find the MC input much more delicate and refined sounding on my system.
The internal impedance of the Lyra is about 5.5 ohms, so that would match with the 25 impedance setting if you use the MC input, but probably 100 or above with the MM input. It is easy to just listen to get the setting that sounds best, don't just rely on specs, that what you got the Steelhead for is its flexibility. You can leave the load capacitance at 0 with MC cartridges.
I believe that the 50 and 55 gain settings use just one half of the small triode, and the 60 and 65 settings use both halves, so you might try 55 and see if the sound is cleaner that way. I find that the 55 setting with MC sounds best overall, but they all sound great.
Thanks, Cjfrbw....you sound well versed in using these combinations. I will try the MC inputs as you suggest and change some of the settings.

I'm surprised the "boys" here haven't stopped by to comment, and while I am no authority on neither the Lyra Titan i, or Manley Steelhead, I might be able to help, and fill in, while the fellas are absent?

If Neil (nsgarch) were to stop in, he probably suggest the 25X rule, using this number as a multiplier times the internal inpedance of the Cartridge (In Ohms)
So, with that being said, and if the internal impedance was 4 Ohms, that would mean an optimum load setting of 100 Ohms.

In regards to this, I understand there is of course leeway with a Cartridge such as virtually all of the Lyras, as well as other brands, and you'd probably find that many users do indeed load these Cartridges to 47K Ohms, just like a MM Cartridge, and are perfectly happy with the sound.

Mr. J. Carr of Lyra does stop in here from time to time, and since he designed these Cartridges, he's no doubt "The Man with the Plan", and can certainly make better recommendations than I can.

I'd probably be correct in saying at this point, with the Cartridge not having many hours on it, you'll probably notice little difference, no matter what load settings you try. This Cartridge is no doubt far from exhibiting its best sound, and J Carr, and others can give you a more exact figure when this Cartridge should essentially be fully broken in. (The Archives might help you in this department, just search Lyra under the Analog Section)

Then after break-in will be the time, to try different settings, and to note how the sound is, and the best advice I can give, is to load it to the best sound that you like, there's really no wrong one can do to a Cartridge with different loading settings. Sometimes 47K might sound a little bit too loose, and lacking control.

As for your Manley's Gain, if the Titan i has the gain that I think it does, which I've seen listed in two publications as being .5mv, then 65db Gain might be a tad too high-hot?

Don't use the volume level comparison of your CD Player to judge what will work best. If the Titan is indeed .5mv, I would think a setting closer to 58db-60db max might be a better choice. With gain set too high, things might get raw sounding, akin to like your overdiving a guitar amplifier. Listen for cleanliness of sound, best combination of quiet background from the Manley, yet with enough gain to not make the Cartridge sound anemic, and that you have to crank that Mac Pre-Amp to 79 to get loud sound.

I think good advice would be to rely a bit more on the MAc's Gain Control, rather than having it too much at the Manley, that perhaps an incorrect setting would be when the Mac's readout is at 12, you're blowing yourself out of the house!

Definitely read the archives, there's mucho info on all the Lyras. Mark
