    Thumbs up Lepai LP7498E Bluetooth

    DIY world. I just got the Lepai amp. And, I have to say this is better than the Topping Tp-60!! I own all t-amps PE has sold and others on the market these days. This amp has a punch that delivers. The price is good. If you haven't seen this amp, check it out. This amp has so much potential. So many people can hook up with Bluetooth at home or outside camping. I want to thank PE for add these amp to there product line. I'm happy as can be. This amp is what most t amps are laking, soundstage with reserve power.

    BR,

    Bart Oetken.

    Have you had any issues with the bluetooth connection dropping out? I purchased one of the bluetooth modules from PE a while back - the white one that's about the size of a tic-tac tin - and it would cut out every 30 seconds or so and sound a loud thump through my speakers. Plus, it put one of the speakers out of phase. So I'm interested in a different bluetooth solution. Sure, bluetooth audio doesn't offer superior sound quality, but it is good enough for most budget builds. And most people I know still listen to MP3's. I recently converted to FLAC

    I don't know about the TA2022 in the TP-60, but I think the TA2020 sounds VERY good.

    You state the LP7498E has "a punch that delivers", but how do the mids and highs sound compared to the TA2020?

    Most of the Class D stuff I've heard(Crown included) sounds a little too "crisp" for my taste.

    Thanks...

    I can get up to about 25 feet away. Until the single dies out. I got them on a pair of vaiston 8" full range with the round Beston ribbon tweeters and they will drive you out of the room. I thought the speakers were junk until this amp. The miss are mellow and highs are clean and detailed. The build of the amp is very light. I was kind questioning the amp but when turned on. OMG man!!!! Try it out. The TA2020 is a good amp. But this is a very clean amp with awesome bass. Try it out you'll love it. I thought this brand was alright until I tried this.

    Hi Belnton, were you using an apple "i" device? There was an issue with the iOS where if you had both BT and WiFi on it caused this issue, if you turn off the WiFi it should resolve the issue.

    Ahhh hahh... I see. Thanks for the tip! Yes, I was using my iPhone. Unfortunately, it would be quite inconvenient for me to turn off my wifi. Now, if only I could figure out the out of phase speaker issue (and no, it's not my speakers. Every other source is in phase).

    I've finally got to use this amp for an outside application. A diy friend said that the bluetooth is worth a darn. I've have not had an issues yet. The more I listen to this little amp it's perfect for big woofers to tiny speakers. I'm getting away from the solid state amps. Still this amp isn't bad at all. There are amps that I've had that are twice to 3 times it's value and they don't even come close to the sound quilty. I've bought alot of worthless buyouts from people and a lot of things that I'll never use. I've compares this amp to 5 different t amps. And this is the winner. I'm not a bluetooth guy but it works. If you guys got a bad signal with the bluetooth and can't seem to find a solution then send it back and get a different one.

    BR

    Mine only cuts out when my kids stand directly in front of the amp. The amp is also surrounded on all sides with equipment so my kids standing in front completely blocks the signal. Otherwise signal is great. I'm about 15-17ft away.
    I ditto Bart, the amp has a lot of headroom. Even when being sourced by the low output of my phone. Nice mids and clean highs. And a much better soundstage than my Onkyo AVR's amp.
    I'd like to try the Indeed TDA7498E amp. Looks really nice and read some great reviews but at $140 with PS or $100 without, the Lepai is so much cheaper.

    This one should sound almost just as good but with better Bluetooth reception: or more power but without Bluetooth.

    Ooh, I want that bluetooth antenna from that FX unit. I don't think the second is more powerful...they both use the same chip and same power supply. At 36V, the chip itself is capable of 128W/4ohm at 1% THD and 80W/8ohm at 1% THD, so any claims above that are bogus anyways.
    Seems the TDA7498E chip is getting pretty popular.

    Yeah., it sells very well... also good feedback on TDA 7498E from Aliexpress many happy customers. There is also a new version of this amp too.

    And this amp is with Bluetooth4.0 Chip, Bass and Tremble adjustment.

    Here is also a nice version and 2

    It would be good if someone could compare them all.

    Do you think if you get a better power supply the amp will sound better???

    Wow there are a lot of amps using that chip. There's several versions of the chip too but the E version is the most powerful. Every other version is lower power for specific applications.
    I don't know how much improvement you'd get from another SMPS. If I were to spend more money on a better PS, I'd make a linear supply but that counters the efficiency and weight savings of these small class D based amps.
