"Mad Dog" by MrSpeakers, modified Fostex T50RP review - Page 312

Specs:

 


  • SEPP (Single-Ended Push Pull) OTL in Class-A
  • Frequency response: 12 hz~100 Khz (-1dB)
  • THD+N: 0.15% (80 mW @300 ohm)
  • Power Output:
  • 350 mW @ 300/600 ohm
  • 300 mW @ 120 oh
  • 100 mW @ 32 ohm
  • Variable Gain: 3,4,5, or 10x
  • Recommended Load Impedance: 32 ohm~600 ohm
  • Input Impedance: 50K ohms
  • Pre-Amplifier Output Impedance: 600 ohms
  • Pre-Amplifier Gain: 3-10x (also controlled via gain switches)
  • Pre-Amplifier Voltage: 10V RMS
  • Power Consumption: 30W (228V * 0.130A)
  • Pre-Amplification circuit includes both driver and power tubes

Thanks in advance for any help

 

My guess would be that it will perform fairly well up to a certain volume level.  There's a non-zero chance that it will distort more at higher volume levels.  Anyway, the best way to find out is to give it a try.  If you find that increased distortion presents itself, then you can always give something else a try.

After seeing the pics posted a couple of days ago, I'm liking the Darth look a lot more than I thought I would, those stickers really are a great match.

+5! I think raised black text would fit the overall look a lot! It'd also kinda match the sole leftover Fostex branding on the headband wouldn't it?

What is the cheapest amp+dac combination that would perform well with the MD+Alpha pads?  My budget is around $400 (including MD) but I guess I could stretch it to about $450 if there is a very noticeable improvement.

Are you in the U.S.?  If so, Modi+Magni by Schiit is probably your best bet for just over that price.  The combo is $200.  If you need it to be less, get the amp first and the DAC second (this is assuming you're playing from Mac/PC, as the DAC is USB-only).

Alright, I will sell some of my crap and look into picking that up.

IMO I'd get the Asgard 2 over the m/m stack. You could pair the A2 with the odac and have basically an end game combo right at your budget of $400.

 

gL!!

$400 including the Mad Dogs - not $400 in addition to the MDs - or at least that's the way I read it.

^^Oh, maybe I read that wrong. I thought he had a $400 budget for the amp and dac...haven't finish the first cup of coffee. redface.gif

 

m/m stack is $200 and A2/odac is $400. IMO it's money well spent though.

If I didn't own my A-GD stuff, I'd go for that.

Minus the ODAC.

It can still work out. I could relieve of that C2 and you'd be ready to go. You've had it much too long anyway. wink.gif

Can anyone comment on how the Vamp Verza would drive these?  I remember reading that the original Vamp struggled with the MD.  The Verza has more power over the original though. (150mW x 2 (USB Mode), 130mW x 2 (iOS Mode)

 

I tried the dt880/250 with the Verza at guitar center yesterday and I did have to get close to max but it still sounded pretty good.  It was also noisy and them being semi open probably contributed.

It's a matter of gain more than power in this case.

 

I can only achieve moderate volume level with the 250ohms beyer on my Fostex HP-A3 (at full volume). It's already loud @ 1PM with the Hifimans 400/500 and it has more than enough gain for the MDs as well (more or less the same volume on the dial).

Thanks. So it sounds like I should be ok since I was able to get the 880’s to an acceptable level with the gain set to high on the Verza. 

 

I really liked what I heard from the dt880’s and almost bought them but I want to hear the MD’s first.  I will be using them for mostly metal.  I like bass but from what I read a little eq and the bass boost on the Verza should satisfy that need.  Plus I have the m100s when I want to go overkill.  They just don’t do it for me with some of my metal.

As they are both 'closed' phones, in your opinion which would you say has the larger soundstage?.. the D2k or MD. 

 

I have MD's (though my Alpha Pads seem to be somewhere in the USPS's intestines, so they have Dog Pads right now; Dan's going above and beyond, though) as well as D2000s, HD580s, and AKG K550s. Amp-wise, I've tried all four on my ca. 1999 HeadRoom Total AirHead, a 2006 HeadRoom Micro Amp with desktop module, and a post-2007 HeadRoom Portable Micro Amp. I run all the amps directly off of the headphone jack on my MacBook or iPhone 4S, using those components' internal DACs.

 

The difference in stage size/width/palpability between the Denon and MD is considerably less than the improvement rendered to both in that department by an amp with well-designed crossfeed. I would dismiss out of hand any amp lacking a crossfeed circuit, and I think anyone else who doesn't primarily listen to binaural recordings should, too.

Headroom Total BitHead. It has adequate drive, a well-engineered crossfeed circuit, and a built-in DAC.
