Alejandro here, 10 years happy with Senn 650s in music room. The chatter here encourages me to swap to new drivers and see what that does. Jazz primary ear diet. With LD1+ hybrid I get all the sound stage I need from good old Meridian 24 cd player. Very happy not to have 5 other pairs of ? When...

Thanks for a great comparison of these two mythbuilders. I have the 650s for nearly 10years. Very much a listener of jazz and classic rock and happy with them. Steely Dan is my favorite for comparing anything, headphones or speakers. I understand that Senn has updated the drivers for my 650s...

HD650 and KossUR55. The first for critical listening and the second for walkin around amidst the chaos of life! Happy with both! Alejandro

Sorry, just musing on a rhyme via Dionne Warwick's old Bacarach tune, "Do You Know the Way to San Jose" which is near my old home town of Los Altos, CA....but I'm in New Zealand....and you're in WS I reckon. No harm no foul. Thanks for the lead on the cables. Want to get a pair for my older...

Yowza! Great Price and that's the way it should be! Canare, cardas, and Furutech...all the way to San Jose! oxox Alejandro

Most welcome Shakur. Be careful...the V4 and all of Neco's stuff is mighty powerful. Watcher ears mate! Enjoy. alejandro

I have the LD 1+ which is the hybrid cheaper model from yours, rolling tubes makes a sig difference too....quite happy with it playing through my HD650s.  I use the long Cardas cable (10') but also have the shorter Charleston midline cable for computer work. Both are good and I love the sound of...

Dearest Shakur I have not heard the earlier models...I have the V4 (not the newer V4.1 which has a different opamp from mine which has the OPA627). I am quite happy with this amps ability to take what I put in my computer drive and hear in my HD650s. I know I could get a different sound with a...

As a card carrying Senn freak, I recommend you go with the Grado SR80i...because you are a metal bass freak! I am a Jazz Snob and not into head banging at all. Acoustic jazz bass is where it's at for me. My BIL likes rock and metal. Good for him. So I bought him the Grados and he is quite...

Well as a Sennheiser believer (started with HD420 in 1981 and now am quite happy with HD650, wish I could afford HD800s) I would recommend you save your dosh for that time you could afford better by that brand. For lesser money, yes the ATH M40X mentioned above, is good for cheap budgets at or...

Look into getting a Charleston Cable for your 650s. You will be surprised how GOOD...for less money! Check 'em out. Alejandro

Seriously loving my after market Charleston Cable for my HD650s...Sennheiser is just trying to suck the life out of us HeadFiers!!! Why does this happen? Greedy b'tards.  alejandro

If you must use HD650 as portable rig you DEF need an amp. They are 300ohm speakers and need amp with grunt. Look at the NECO V4 or any of his products. Super! Good hunting! alejandro

And you're right again SkyBleu...the thickening you refer to I can think of as a depth or fullness in the midrange indeed. Yep the V4 fits that quality well. And that's where that full snap exceeds the quality of my LD1+ which is a very close second in SQ. Remember, if you get a copy of Bill...
