Initial impressions - Little Dot I+ hybrid tube/transistor headphone amplifier - Page 2

post #16 of 20
I have the 770-250's and upping the gain on the LD I+ helped improve soundstage and bottom end quite a bit.

I already ordered my LT1364 from digikey, so we'll see if that also makes a diff.

I will be sure to use the high gain setting when I get my 250 Ohm DT150s.

I never found Sylvania Gold 408As (at any price), so I went ahead and ordered Westinghouse instead.
(There was also a more expensive pair from a company called Tung Sol, but I have never heard of them. Are they good?)

Just got my Grado 325i's today. Not broken in yet, but it seems to be a MUCH better match for the LD I+ vs the DT770's. I set it back to the lower gain and w/ the source off, it's dead quiet with the Grados.

I have shipped all but one pair of the best ones that tested "excellent" (where GM measures > 71) out to Head-fiers. This has been on a first-come / highest-quality basis through the FS forum section. I still have a few that tested "good" where GM measures <71. Highest quality ones will continue to go out on a first come basis until they are gone. After that we will have to pay eBay prices. I almost hate to post this information because eBay tube sellers are likely reading these threads and might increase prices even more.


My two headphones that sound good with this combination are both low-impedance headphones. Your Sennheiser HD-580 is a high-impedance headphone. So I would take a guess that it might not work very well. Mind you that I am only making an educated guess and you will have to seek out and ask others who actually own it.

I think you might want to read some threads on how the Sennheiser HD-580 synergize with other headphone amplifiers from Darkvoice or perhaps a Little Dot IV SE if you are seeking tube amplification with that high-impedance headphone.

How easy is it to change tubes?

If I have an ms2 would it be worth changing to a 408A?

Very easy to change,,best tubes with my 325i's so far are Mullard EF92.Didn't like 408A's ,seemed to run to hot for my liking.Prefer the sound of the ef92's, nice and smooth to my ears.
