It has begun!
I put the MPH's over a box for a few days. Big improvement in fit. Maybe my heads shaped like a box? I've been running the Philips non-stop for a few days too. They are sounding really good out of the PC HP jack. Sure would like to try them with the ModiMB.
As I said elsewhere, I have several nicer sets of phones but for the main types of music I listen to, I could easily live with the 9500s as my only set.
I've got the original Fulla.
This still brings a smile every time I use it.
Drives my Sennheiser 598's very well.
Update on the system. The Vali 2 is here. Now this is getting the SQ right. I'm using a ModiMB/Vali 2 with the SHP9500S. It's a great combo.
Could the vali 2 replace my Cambridge Audio 551 Azur as a phono preamp with the Marantz 4400? Would there be a point?
It would be nice to have a tube headphone amp that can also serve as a preamp.
The Vali 2?
It's a headphone amp, not a phono preamp.
On their website its mentioned that it could also be used as a preamp, but since its not its main job I'm guessing it wont be any good at it.
There is a difference between a preamp and a phono preamp. A phono preamp is meant to amplify a signal from a turntable (which generally is very weak) to line level (a standard line out from a CD player or tape player or whatever). This often involves 100-1000x amplification depending on if you are using MM or MC.
The other thing that a phono preamp does is correct the RIAA EQ curve. In my understanding, because of the very physical nature of vinyl, it is possible for heavy bass to drown out higher frequencies. To compensate for that, the recording put on the vinyl generally has the lows dampened and highs accentuated. When the signal is passed through a phono preamp, the reverse EQ is applied to balance it out (i.e. it boosts the lows and dampens the highs). This is why rumbling from noisy platters or other low frequency vibrations occur with vinyl sometimes; those unintended and external low frequencies are getting a boost.
The Vali, on the other hand, works as a preamp in the sense that it sends a signal that powered speakers or a power amp could use. Assuming it is like the Valhalla 2, which I have, that preamp signal is affected by the volume knob on the headphone amp, so if you hook it up to the Marantz, you may get to play with two volume knobs, trying to find the best setting. However, it will not function as a phono preamp.
If you want a phono preamp from schiit, they have the mani which is a stand-alone, or the Jotunheim and Lyr 3 have the option of having a phono preamp added to them, but both of them cost a bit more than the Vali.
Yeah, I have the Mani (and a couple other ~$100 phono preamps) and it's a pretty nice little piece.
You can use a turntable into a phono preaml into a headphone amp into your headphones. I don't usually do that but I've had such a system hooked up in the past.
I use that set up. My phono preamp has two outputs so I was able to use one for the headphone amp and one for the integrated amp. Now I use a Realistic Tape Control Center (fancy name for a box with four inputs, four outputs, and switches so you can select which input goes to which output, within reason).
Thanks for the detailed responses!!The Lyr3 looks promising if it can indeed serve as a dac/phono/ and headphone amp plus the tube.I will consider it.
The Lyr3, to my understanding can have a DAC or a phono preamp, but not both. Like the Jotunheim, there is a spot for a module that they can swap out to either be nothing (and this is just a headphone amp), or have a dac or have a phono preamp:
That picture is one with the DAC. They did not have a picture of one with the phono preamp installed.
While I am sure they exist, finding a headphone amp with dac and phono preamp may be a challenge (I admit I have not looked too hard).
