Hey Guys, been running my TH-900s out of a dB Labs Tranq DAC > Gilmore lite for 2 ish years now, sound signature is a little dry and impersonal.
Purchased a ifi Micro iDSD, sound alright, but not different enough to make me want to keep it.
Really want to try some tubes, add some warmth.
Anyone got any tube amp recommendations? (WA7 seems like im paying for a DAC I wont use and ZDSE is a little out of my price range)
I very late in responding to this post, but it may still help others that are searching for a tube amp to pair with our awesome TH-900s.
I am currently using the iFi Micro iDSD as my desktop DAC, and recently bought a used Musical Fidelity X-Can V8 amp. I am absolutely loving this combination!! The X-Can’s output impedance is just 2 Ohms, considerably lower than many amps. So it should play nicely with low ohm headphones like the TH-900 and Grados.
I only had it a couple of days and decided to upgrade the tubes and the PSU. I bought some matched Russian tubes and the "Little Pinky" SE from Mike at Rock Grotto, also known as Pink Floyd. I've had great experiences with the Mike and his Little Pinky, having owned two of them that I used with the MF X-Can V2 and V3, several years ago. Mike made a large purchase of NOS 6N23P-EB military grade tubes with chrome pins. They're branded Voskhod 6H23N (Rocket Logo) which were made in the Kaluga plant / Russia. I've never heard of them, but they sure sound good.
As most of you may know, the MF X-Can V8 isn't made anymore, but do come up on Audiogon every once in a while. MF also made a separate power supply for it, but they're even more rare. So for just a tick under $600 with the mods, I've got a great tube amp that pairs very well with my 900s. Even the Shure 846 sound pretty good on this amp.
I've cycled through a few amps trying to find a good match for the Fostex, which are my favorite cans. So far I've tried it with the Burson Conductor, CEntrance M8 and Fostex HP-8, and to my ears this is the best combination by far. This thing has gobs of power, most of listening has the volume dial just below 9:00, with 11:00 the absolute max with the right recordings. It packs quite a punch, with hard hitting bass and clean highs. It's hard to wipe the smile off my face, I love these phones even more now!
I should add that this is just my opinion based on my ears, playing my kind of music on my system....YMMV!
Happy Motoring!
