Most "holophonic" 3D sounding tubes for my MKIVse?
I've had my MK IV SE for about a week now. It came with CV4010 tubes which I found very neutral sounding, very SS like, which isn't exactly what I was looking for, so I bought some Russian 6Zh1P-EV tubes. BIG difference, I definitely like them better, but of course the upgraditis bug strikes...- MatthewK

Am I the only one who hates all these bright LED lights??
EVERYTHING has bright LED lights now. My computer, monitor, keyboard, cable modem, router, E-mu 0404 USB has a ton, Aphex 204, heck even the power strips. Those blue LEDs are the worst, they are always super bright. Then you've got the blinkers, like the ones in routers. I've got those pesky...- MatthewK

Tubes with the most bass?
My LD MK IV SE is in the mail, and it will be my first tube-amp. It's supposed to come with 6H30Pi Gold Pin power tubes and M8100 driver tubes. I also have some 6Zh1P-EV tubes coming in the mail from the Ukraine which will probably arrive a bit later. What driver tubes can you recommend for...- MatthewK

6H30Pi Gold Pin vs 6H30P-DR
So what is the big difference between the 6H30Pi Gold Pin and 6H30P-DR besides reliability and expected life? How big of a difference is there in sound quality?

Mod the LD MKV into Balanced?
I was thinking, the Little Dot MK V is almost a perfectly balanced amp, except for the output (1/4) and the inputs (RCA). I don't have enough know-how to do a mod myself, but I thought maybe I could get a conversation started. Is this mod even possible and/or practical? Here's a convenience...- MatthewK

Does anyone use a Little Dot MKV + Denon D2000/D5000?
I'm considering the Little Dot MK V Dual-Mono amp, but I'm concerned it might not adequately power such a low impedance 'phone as the D2000/D5000 (25 ohms).. Does anyone have any experience with this combo?- MatthewK

Desktop Amp for Denon D2000
The impedance for these 'phones is 24 ohms, and the input rating is 1,800mW. The source will be the E-mu 0404 USB's balanced line out. Can anyone recommend a good desktop (non-portable) amp for under $300? Thanks in advance.- MatthewK

My 0404 USB is in the mail (I'll probably receive it Monday or Tuesday). I'm thinking of replacing the power supply with something of a higher quality.

Looking for non-portable DAC/Amp
The Zero looks interesting. I wish it had two mono/single DIP sockets though instead of using dual-channel chips. Are there any alternatives that are under $250? It's fine if it doesn't have USB, as long as it has SPDIF inputs. In fact, I might even prefer that over USB. Another requirement...- MatthewK

OPAMP with the most bass impact?
What 8-DIP opamp (single channel) has the most bass impact in your opinion? Thus far, I've tried the OPA134A, OPA627AP, LME49710NA, and the AD8610. I would have to say the AD8610 seems to have the most bass impact of those listed. I also like it's lively sound. So I'm wondering if there's...- MatthewK

What determines impedance in an amp?
I ask because the manual for my PD XM5 portable amp says it supports headphones with an impedance rating of 24 to 600 ohms. Do the opamps determine the headphone impedance it supports? Thanks.- MatthewK

MiniBox-E+ ...or... iBasso P2
MiniBox-E+ or iBasso P2 Which one is better? Why? I'm narrowing it to these two because they both have a bass boost option, and I've read good things about their sound quality, but I'm still open to other portable amps with bass boost.- MatthewK
