The Little Dot uses a Bipolar Operational Amplifier chip to do all the voltage amplification and bipolar transistors in Class B configuration to do the power drive to the headphones... the valves (tubes) are pentodes in Class A but driving into resistive loads (no matching transformer) so won't display the odd harmonic colouration so loved by Oliver, I guess they will tell you the power is on. Also the mains rectification is done on the same circuit board as the amplifer, which cannot help.
However, if you've heard one and like it, all this is irrelevant.

If you've got a better match for a SR325i at that price then I'm all ears.

^ no, just pointing out you shouldn't buy it just for the valves, all the hard work is done by transistors, (and that's not a bad thing of course), but it is a hybrid and not a valve amp unlike the Little Dot II and Little Dot III.

Right, but the unlike the 2/3, the 1+ is tailored more towards low impedance headphones, which is what the 325's are (32ohms). I just need to smooth out the harshness and tame the brightness a bit and I'm all set.

Sonically, if it sounds more "solid state", the match with the Grado may be nice (Grado sounds very warm and analogic).
But i somehow agree with Dean...if this hybrid doesn't sound valve but with all the troubles that come with valves...(replacment, etc...), is it really worth? Well, what's your goal actually? Are you looking for an amp for indoor listening? If it's the case, the Triad audio Lisa III should be considered as well. http://www.triadaudio.net/Triad_Audio/Home.html If you want something really portable as well, then it's RSA Mustang P51 or Headamp Pico, but of course it has to be powerful enough for the choosed pair of HP.

They're open cans so indoor. Supposedly the I+ synergizes well with Grados and at the low price point of the amp I don't think tube replacement will be too much of an issue. Although I've been searching high and low for the discontinued Gilmore Lite, which is my first choice.

I forgot an excellent subwoofer brand: Velodyne http://www.velodyne.com/[/QUOTE] Yes...I have been looking at a 10" model DQR10 or something like that.........Assuming I go with a bookshelf model speaker......I have been looking at a Klipsch bookshelf, but I need to find one local to go and have a listen first.
Still looking....Thanks

My setup right now is 2.1 only. It includes a Marantz receiver with a marantz cd player, v-can headphone amp, ath-w5000 headphones, 2 definitive technology proMonitor 800 speakers and a Definitive technology pro 800 sub. I'm going to replace the two speakers for a pair of Bowers&Wilkins 685s and leave the little ones for when I build my home theater set. This one is mostly for music.

Yes I know.....I have decided not to get a sub for my system.....I am still shopping for new speakers. Currently looking at B&W CM1, they have amazing bass response, EPOS and Klipsch all bookshelf models. The problem is not having a store that carries stuff you can audition. Also looking at the NAD C356BEE integrated amp. My system is old I have an Onkyo Integra TX-870 receiver (20yr old), Sony CDP302 CD deck (25yr old), ADC SS100SL EQ (20yr old), Audio Technica AT-LP120 Direct Drive Turntable (1yr old), Bose Acoustimass speakers (20yr old).....Everything works fine, but now that my kids are grown and we are not spending all our available cash on them....I am looking for new equipment. I am kinda glad I waited since technology has improved so much in the past 10yrs....

Among your electronics, the weakest part is the marantz amp |

The Nad amp and the BW speakers are good musical choices, you'd get a second hand Nad CD (any model, some are for sale at less than 100 dollars) because the Sony will not do justice to your (future) new gear. |

Of course. Another option is to gather all in on system.

Ohh I agree on the CD player, I forgot to mention I will replace that one too.....I was looking at a NAD or REGA CD player, there are some stores in Seattle that have pretty good used equipment.
....I am 100% a 2.0 channel person, always have been. The older equipment I will give to my kids for their Xbox room so they can use it for gaming audio.

Your system appears to lack one vital component Oliver.
