sorry to hear you are going to sell the DT, I love mine for what it does best, single amp patches at volume. Unfortunately, there is NO good low power tube solution. I do not believe you will ever be satisfied with a tube amp for home use at low volume settings. I suggest you consider a decent stereo SS power amp and a 2X12 cab with a stereo option. This will allow you to make full use of the POD's capabilities as a guitar solution including creating dual amp patches, using the stereo effects and you won't have to play around with the 4 cable method. You can make all your patches with full amp models and the patches you create for headphones and monitor will require only minor EQ adjustments with this setup even when you get to play live. A nice 100x100 watt stereo amp and cab will set you back not much more than a low watt tube amp and give you more capabilities for the style of play you describe and the volume levels you wish to use than a tube amp. You do not gain anything special with a tube amp other than a DT model when using the POD. In fact, other than for the specific tones that particular amp gives when cranked, I think you would be taking a step backwards.
Thanks for this, all interesting and relevant. I really love the podHD..was playing with a strat through my SRV patch today and the thing is just incredible..to the point where I agree a tube amp in some regards is not actually necessary. I may well expand my gear in the future with a SS preamp rig as you suggest.
However I don't agree with all of the above as I've already found an ideal low-"er" wattage real tube solution in the OR15H I purchased earlier this week. This thing is the dogs balls! Even in half power (7 watt) mode I do need my THD hotplate for around 8-12db volume attenuation in my flat but tone is well preserved. Single channel non-master volume all tube amp with simple 3 band EQ and no infernal tweaking required!! Plug and play. Using a sweep of either the volume knob on my guitar or the amps gain knob I'm not exaggerating when I say I can go from shimmery cleans to classic rock to Slash-esquel hard rock to heavier 80s Metallica without any special tweaks...all within the remit of a single channel. For me, usability, tone and feel are all superior to my DT25 which I've kept for honest comparison in the short term.
I've even set up a hybrid solution for playing the OR15H through headphones if I need to: amp - hotplate line out - podHD aux in through podHD Flip Top pre (very flat response) with v30 4x12 cab sim. Sounds very like the amp through a speaker. Probably a bit OTT with this method but shows what's possible.
As much as I love Line 6 for their modelling..... I'm glad to be rid of all the glitchyness, fuss and multiple patch requirements with a DT involved. Maybe if all I did was play at volume on stage but even so I genuinely prefer the Orange tones to all my best patches, as great as they are.
