Hey guys, Just trying to see if there are any people out there who have experience with the Demeter VTHF-300M namely with the HBP-1 Preamp, but the VTBP-201S will work as well. There's a few threads already out there, but I thought I'd like to see if people are still using some of these amps with the Class D's becoming so popular. I've got the opportunity to go own a HPB-1 / VTHF-300M and was curious if there are any experienced users that could offer some comments. Not many threads on this combo, but any I've read have been very positive. The Aguilar DB680 / DB728 seems to be more sought after piece in the rack mount all tube setup. Very heavy, like the Demeter, but with a whole lot more tubes under the hood and 400W of tube power, crazy! I really don't have need for 400W, but you know having a little more with bass always tends to help. A little more background info, I've got an Ampeg SVT-2Pro and a hot-rodded Mesa 400+. I like the Ampeg, but the Mesa is now my favourite as it now has an adjustable bias installed, some new Groove Tube JJ Power Tubes and Sovtek 12AX7's. Sounds fantastic. I really do like 6L6's for bass. The new Mesa Strategy Eight : 88 is on my list as well to check out, just waiting for one to make it up North. 465W of power seems deadly……but man that amp would be more expensive to re-tube than my 400+ these days. I have a feeling that the Demeter rig might be more what I'm after as I'm looking for a little more cleaner and hifi sounding amp. I will be using Aguilar Cabinets with whatever I choose to go with. Curious to get any feedback. Interesting thing that Aguilar has discontinued there pre/pwr all tube rigs years ago, yet Demeter is producing the VTHF-300M, and oddly enough hasn't integrated Speakons yet! Thanks for reading.
