The power amps in the Quilter and TH500. The TH500 uses the ICEPower 250ASX2 module that outputs 500W into 8R. Slightly more  but 50W is neither here or there. Any difference you hear is likely due to the Pre-Amp implementation. 

The Aguilar TH500 puts 250w into 8ohms and doesn’t kick anything like as hard as the Quilter. For sure the preamps are voiced differently but the Quilter has simply much more juice on tap.

Are you certain about that? The 250ASX2 is a stereo module that gives 250 a side into 4 ohms or 500 bridged into 8. The Aguliar site states 250 into 4 or 500 into 8. I doubt they'd spend the extra on a stereo module for a mono head.

Their implementation is different than most others IME. It's just how they chose to use that part.

There is also a lot more to the IcePower specs than what's published, in fact most of the important information about the module resides between the lines, and requires a lot of experience to exploit safely, with high reliability.

      Genz Benz Streamliner 900 bass amp for sale with padded gig bag .. in original box with manual.
      I have owned this amp since new. It is extremely light and portable, and very LOUD. I have gigged with it in different places, with a single cab, 2 cabs, through a PA and it has delivered every time.
      The tube input overdrive is very usable and can be used to give your bass some extra punch, or, full on overdrive ... up to you
      Please see photos ... it is in good condition (a few cosmetic scratches as you expect from use) and in full working order.
      Here is some of the relevant info from the manufacturer:
      Output - 500 Watts @ 8 ohms; 900 Watts @ 4 ohms
      Weight - 2.9 Kg
      Size - 8cm x 25cm x 30cm (approx)
      The 300 volt All Tube Class A preamp design is driven by three 12AX7 preamp tubes utilising six gain stages. The preamp design features an intuitive and highly effective tone network which is a unique blend of a modified passive Baxandall network for the bass and treble along with an active tube driven mid filter with selectable mid frequencies. The versatile all tube preamp exudes a fat and rich tone that remains articulate. It can be used to simply add warmth to your natural tone or it can be dialled in to provide a wide range of natural tube overdrive.
      The powerhouse behind the Streamliner™ is a Class D amplifier and SMPS module, enhanced with our Patent Pending P.H.A.T. (Proprietary Heat Abatement Technology) topology. This delivers robust and reliable, high output performance in a tremendously compact and convenient package.

      Selling this GR BASS 700+ lightweight bass amp head. Completely Made in Italy, this is a small but very powerful bass head that delivers 350W at 8 ohms and 700W at 4 ohms.
      I'm selling this as I really don't use it much, it has seen mostly home and some live use but is in great condition. The fan is slightly noisy but it can be turned on and off, and when really needed in live situations it can't be heard at all. Features include a Sub Filter switch to remove inaudible sub frequencies which increases you speaker efficiency, a 400Hz-800Hz frequency selector switch for the mids, a dedicated DI volume which also acts as a headphone volume, an AUX input, headphone jack for silent practicing, and a handy mute button.
      Comes with a power lead and a handy Gator Cases carry bag. Collection in Hackney, London or shipping at buyer's expense. Thanks for looking!
