I've got speakers ranging from 86db to 91db and the T70 powers all of them with ease,with the Trends although its a great amp,I would'nt pair it with any speakers under 89db,but the Pop Pulse sails thru all of my speakers with ease.

The only place I know is Audiomagus which they sell online and have a 30 day trial,they sell the Trends,King Rex,and they can get any T-amp you want and they have a big selection of dacs to.Is T-amps the only amps your looking at?because it seems that you may need more conections than most T-amps provide.

There's plenty of hiend shops arond here years ago Dayton used to be 1 of the audio mecca's in the midwest.What kind of gear are you looking for? I use the wall,I've found power conditioners to limit dynamics to much.and no problem your not bugging me,by all means ask any question you need to.

i am new to the audiophile gear. i have always wanted hi end gear. i just couldn't justify it. so i forgot about it. until i heard some $30,000 Martin Logan speakers along with 2 Classe amps. i was sucked back into audiophile gear. how ever i do have a budget. i currently have an older onkyo a/v receiver and my polk rt800i speakers. i have a broken cd player and sold all of my surround sound speakers. i use a Yamaha ysp 3000 for my movies. (it's sounds ok for me) but i have never had a truly hi end music system. i really only care about 2 channels. i am trying to put together something that will sound very good for a good price. so the price and reviews of T class amps got me interested. i like the ease of using the ipod (lossless file) now i would like to try these polk speakers with a good amp. i wonder about dac's and power conditioners. also how could i give eack speaker its own amp. such as the pop pulse you have recommended.

I've bought from Audiomagus before - highly recommended. I notice they don't have the PopPulse in stock right now. You may want to give Obad Imports a look, their website says the PopPulse is in stock:

http://www.obadimports.citymax.com/catalog/item/4377302/5833179.htm

I've run the Trends amp with several different types of speakers, and while the sound quality is really, really good, it never really went loud enough for my liking.

The times where I did turn it up it got quite distorted.

Don't get me wrong, Andrew, it's not that I don't think the ipod can't sound good. It's just that I don't like Apple.

To each their own.

I think I can say I hate all the 'i' products. I-Pod, I-Mac, I-Book, I-CRAP. F#%#ing Apple man.

Andrew, congrats on the purchase man. Nice little amp.

Yeah, a lot of hate for Apple. It's proprietary, over-hyped fluff.

Yes, I do own an mp3 player. It's a Sandisk (the same guys who make all the flash memory and SD cards). It's awesome, and 1/3 of the price of an ipod.

since we are already off-topic:
not everyone hates apple.
I'm typing this on an 8 year old ibook that is a portable music server-command center (with firewire port for external lossless hard drive) in addition to being my everyday workhorse for prepping (I teach), writing (publish or perish), email and surfing. it cost all of about $1199 in 2000. how many others can say the same of their 8 year old wintel?
so, there's some hype and fluff, but it is well-engineered gear with--when you are familiar with it--a very intuitive, efficient & ergonomic interface. there's a reason ipod's made apple a lot of money, and ibooks and imacs before. this isn't a rant or attack and is totally off thread, but when I hear the word "hate" regarding anything, esp. sth. I like, I cringe.
peace

The T20 has a built-in DAC. It's probably not too shabby.

Andrew, I've used the SuperPro 707 with really good results.

Andrew -

You can't use a DAC with an iPod, if that's what you're trying to do. They don't have a digital output, well at least not in this sense.

You'd need the Wadia iTransport to get a digital signal, then feed a DAC. The iTransport is about $400 or so.

Instead of a headphone line out to RCAs, have you looked in to Ipod docks? They bypass the internal amp, which is the downfall of the iPod. They'll also give you remote control and a few other options. I haven't used one, but a few well respected ones are Marantz, NAD, and Arcam. I'm pretty sure they can be used with any system, not just their matching brand. Confirm that before you buy though.

The Arcam looks the best to me. A huge feature it has is being able to turn the charger off, therefore saving the battery. Its not good to constantly charge the battery.

i am planning to use an ipod using lossless files or just a cd player and may be a dac. i am thinking that if i like the king rex i am going get a king rex pre amp and another t20 amp bi amp my speakers then work towards the power supplies and then a new cd plaer. got any advice on good cd players.

I was under the impression Andrew would be using a PC (or Mac) to connect to the Rex, hence the need for a DAC. Never mind, my bad.

Yup, it's bad to constantly be recharging your battery. If you recharge it before the charge is completely changed you'll shorten the battery life and/or reduce the charge it can hold.

T, have you heard the Glow Amp One? Any ideas on how it might compare to the Pop Pulse T70i (other than being more expensive)?

No,I havent Christopher,the Glow is only 5 watts its a SET,good for single driver and very efficient speakers.If I had a pair of Omega's or good horn design I would'nt hessitate to get the Glow its a well respected amp,and very underpriced.I thought about a pair of Omega's and a Glow a few months ago,but I started saving for a big amp.

I've got a pair of Tekton (Fostex FE127E) 4.5" SDFR that are 91db and sound real nice with my Trends, but the Glow Amp One, and now the Pop Pulse T70i, have me curious.

I read a couple of not very favourable reviews of the Glow Amp. Even on in the AudioMagus forums there was mention somewhere that there were "issues" with them.

"We agree -- the DAC is not the GLOW Amp One's strong suit. We've mentioned it to the guys at GLOW and I'm sure they'll look for a solution."

In the same thread there is mention that it is shy on bass.

That's the problem with Internet-Direct products, you have to trust someone else's "unbiased" opinions.

The safest bet I guess when dealing with interet-direct is ensure they have a generous return policy.

The Glow amp does look really, really cool, though, and AudioMagus is a reputable company - I've ordered from them before.

The Glow Amp return policy is 30 days what I gathered from a friend's experience. I did not test it in the best environment for it, but I did surmise that it could work better if you messed around with changing out tubes. YMMV. The glow thing was more a nuisance than a feature IMO.

I wouldn't do it.

$500 for 5 watts seems like a lot too.

But what do I know? I'm a solid state kinda guy.

You should know why you are buying the Glow before you order one. In other words, what's your attraction to this amplifier? Because it got a good review? Because it's single ended? Because it's cheap? Or just because it glows?

I ordered the Glow amp a few months back after the marketing guy for Glow saturated the forums with his ads. According to him I am the only person who has sent this amp back for a return of money.


OK


But surely I can't be the only person who ever heard the faults I observed with the amplifier.

If you are looking for a SET, this is not your amplifier. First of all, it is not a SET. The EL84's used as outputs are small pentodes and they are run as pentodes - not as triodes. This is not a single ended triode amplifier. Big difference IMO. There are some decent sounding single ended amplifiers that do not use triodes but this isn't one of them from what I heard.

If you are wanting the "magic" of single ended triode operation, this isn't going to get you there, I think you would be better off with a good UltraLinear amplifier if "triode on the cheap" sound is what you want.

There's no information included or supplied by the manufacturer's web page to guide either the novice or the experienced tube user. No mention is made of the output impedance of the various taps - 4 and 8 Ohms labeled - which is a small matter to some but something I consider very important since any tube amp will undoubtedly interact with the speaker load and the frequency response will vary from flat response according to the amplifier's output impedance working against the impedance load of the speaker. This approaches the Bose attitude of "you don't need to ask that sort of question" territory in my book.

The amp is rated at 5 watts with no real indication of what the amplifier can actually produce into a load with a minimum THD spec. I would say this amp is on the very puny side when compared to any other amplifier I've had in the house. The two T-amps I own are rated at one more watt (with a full 1% T.H.D.) than the Glow (with no specified T.H.D.) and they provided substantially higher levels into the same speakers. The Glow is a wuss! Be prepared to buy 100dB speakers if you consider the Glow 'cause I don't listen that loud and my current speakers are running at about 93-94dB @ 1watt input.

The Glow did a few things very well, but not enough things and not well enough for me to even consider keeping it. It has a nice amount of subtely with vocals giving an interesting nuance to familiar material but it lacked that ever popular PRaT which I have to have before anything stays in this house. In the area of integration of players and just plain playing the tune, the Glow amp is one of the worst I've ever heard. The T-amps stomped it in this area - even the stock $39 plastic model.

And the glow feature is just stupid!

The company was very good about the return and I received a cash refund within a week's time. So they are deserving of praise there and they are still offering the 30 day return policy if you still want to try the Glow amp. I wouldn't waste my time if I were you but I'm not you and you might not be bothered by the same things I found lacking in the amp. But I would strongly suggest you look elsewhere if you want a SET, if you want a cheap amp and if you want the system to play the music.

As usual, Jan cuts to the quick.

I'm fairly certain that what got me curious about the Glow Amp was the same thing that motivated you to place your order, namely all of the those GLOWing reviews (pun intended).

I have never owned a tube amp, SET or otherwise, so am curious, but yes, it is a bit pricey for 5W, but all watts are not created equal, and if Jan says the these are crappy watts, then I suspect they're crappy watts.

Anyone else hear the Pop Pulse T70i?

For me, yes. But I learned long ago I don't listen the way most others listen and the amp might work for you. None the less I still find the "glow" crap stupid and distracting. You have 30 days to decide and they will refund your cash, so you'll only be out the shipping cost back and forth.
