I ordered two LM6172's. Should I have ordered 3 and replaced all the opamps on the STX? I have an HD650 and HD600 and hoping the LM6172's give me more focused sound stage (right on stage with musicians), warm sound and high extensions. At least that is the op amp I am looking for. Any recommendations anyone? Should I get a tube amp? Little Dot III or DarkVoice 336.
I have the ST and recently got the Little dot MKIII. Its...meh...ok I guess, I don't like it very much. Used with K701, HD650 or T1, it lacks resolution and fidelity compared to the STX output. It doesn't sound as clean and natural. Its soundstage is slightly bigger, but whole tonality of the sound is shifted. I would not call it warm exactly. In fact, to my ears, its highs are quite prominent, it sounds brighter than STX headphone output. In my opinion its now worth the money. Its just not as good as the STX technically. Now, if you'd like to tube roll and find a darker sounding tube...might work for you, but don't expect miracles. A cheap tube amp is always a hit and miss.
IMHO entry level SS amps sound far better. Like the Musical Fidelity V-CAN MkII for example...nice smooth, non-fatiguing sound, but still very clean and detailed.
